Description

The invention relates to dendrometry, for example, in a component analysis of a forest stand, as well as to engineering ecology in the study of the component ecological balance of a forest stand, and can be used in the conservation and protection of the forest ecosystem, the arrangement of the forest landscape, ecological monitoring of the forest environment within the forest stand, technological monitoring processes of natural regeneration of woody plants and the forest as a whole, taking into account annual changes in the distribution of the diameter of the root part of growing trees, undergrowth and undergrowth, overgrowth, shrubs and shrubs.

There is a method of analyzing a tree trunk, including measuring the butt part (see, for example, the textbook: V.K. Zakharov. Forest taxation. 2nd ed., Rev. And add. - M.: Timber industry, 1967. - S.301, 304), including two private processes: a) field operations for the selection and measurement of trees; b) cameral processing of field materials. According to the first part, the analogous method includes actions: selection of a planting site and its characteristic, selection of one, several or all trees with a description of their taxation indicators.

The advantage is that according to this technical solution, the selection action of all trees of the stand is possible.

The disadvantage of this method is the constant height of 1.3 m measuring the diameter of the tree trunk and the same degree of thickness for all measured trees. As a result, trees with a diameter of only 6-8 cm or more are measured (4 cm or more abroad), that is, not all woody plants are measured. For example, undergrowth is not included in the taxation process, which receives a characteristic only by the number of trees.

There is also a method of analyzing a tree trunk by measuring a tree lump with a diameter at a standard height of 1.3 m from the root neck and further according to Patent No. 2201593, which includes selecting a test area, selecting a tree on a trial area, describing the properties of the selected tree and its place of growth, establishing a location the neck of the root, measuring the distance on the trunk from the neck of the root.

The advantage is that the distance from the root neck is taken to be of multiple lengths, but starting from a standard height of 1.3 m.

The disadvantage is that in this case, the multiple length refers to the trunk section above the standard height of 1.3 m and thus the difference in the thickness steps of all sizes of woody plants growing on the selected trial area is not determined. The diameter measurement at a standard height is possible only for forest trees with steps of a thickness of at least 8 cm. Therefore, the disadvantage is the impossibility of measuring at a height of 1.3 m the thickness of the trunk of small woody plants of undergrowth, undergrowth, shrubs and shrubs, overgrown on stumps. Existing methods for measuring the diameter of trees are not aimed at woody plants, but at adults for making round timber from them.

The technical result is the expansion of functionality and improving the accuracy of the analysis of the trunk in the butt part of any sizes of woody plants growing on the trial plot.

This technical result is achieved in that a method for measuring the lump of a woody plant, including selecting a test area, selecting a tree on a trial area, describing the properties of the selected tree and its growing location, establishing the location of the root neck, measuring the diameter of the stem from the root neck at a standard height of 1.3 m, characterized in that the selection is performed for all types and sizes of woody plants growing on the selected test area, the diameter of the trunk of each woody plant is measured without destroying it I, at the same time, the section of the trunk from the root neck to the calculated height, which depends on the diameter of the trunk at the same height, is taken as a comet of a woody plant, and with an increase in the diameter of the trunk of a woody plant, the upper section of the butt is taken to be not less than the standard height.

To take into account all biological species of woody plants of different productivity in wood, for the butt of a woody plant, take the trunk section from the root neck to the estimated minimum and maximum heights, depending on the diameter of the trunk at the same height along the lower and upper boundaries of the confidence interval according to quantitative data from the following table :

With an increase in the diameter of the trunk of a woody plant, the upper section of the butt is taken to be at least a standard height according to the formulas of the boundaries of the confidence interval:

; $${\text{h}}_{\text{D}}^{\text{min}}=\text{one}\text{, 3 (1}-\text{exp (}-\text{0}{\text{, 064732D}}^{\text{one}\text{, 12520}}\text{)))}$$

According to the results of measurements to take into account biological species of woody plants for low and medium wood productivity, mainly in forests of middle and high latitudes of Russia, the trunk section from the root neck to the estimated minimum height depending on the trunk diameter at the same height over the lower boundary of the confidence interval, measurements of woody plants on the trial plot are performed according to the distribution of the steps of thickness and height of measurement, depending on the diameter of the upper section komlya on the groups given in the table:

with the symbols of the trunk diameter groups of woody plants:

1 - small seedlings and seedlings (step thickness 0.01 cm);

2 - middle seedlings and seedlings, undergrowth, shoots (0.1 cm step);

3 - large seedlings, small undergrowth, shrubs, shoots (0.2 cm);

4 - middle undergrowth, shrubs and shrubs, shoots (0.5 cm);

5 - large undergrowth, trees, undergrowth, large shrub (1 cm);

6 - forest trees (step thickness 2 cm);

7 - forest trees (step 4 cm thick).

To form a continuous scale for measuring the diameter of the trunk of woody plants, taking into account the accuracy of measurements by groups of values of the diameter of the trunk, measuring tools are used: 1 - micrometer; 2-4 - vernier caliper; 5-7 - measured fork.

The essence of the technical solution lies in the fact that taking into account the division price of measuring instruments, a continuous scale of diameters is created, from which the height of measurement of a given barrel diameter is calculated by the mathematical function of the growth limit.

The essence of the technical solution also lies in the fact that measurements can be carried out on woody plants of any biological species, age, shape and size.

The positive effect is that the proposed measurement method allows you to integrate in a complex way all the elements of the forest on woody plants, without isolating trees from the plant community. This will allow us to switch to the ecological taxation of woody plants and, on the basis of variable measurement heights for various trunk diameters, to evaluate the component ecological balance of a complex forest stand with the inclusion of undergrowth, undergrowth, shrubs and shrubs, and shoots. An analysis of the components of such a complex system more objectively allows us to evaluate the indicators of environmental sustainability and instability of individual tree species and to give predictions on succession processes. The greatest effect will be achieved by modeling the dynamics of succession of elements of woody vegetation on the trial plot after a series of long-term measurements on the proposed continuous scale of the diameter of the trunk. Moreover, the method is applicable in any forest growing conditions, which in the future will allow us to evaluate the influence of forest soil and other subsystems of the forest ecosystem.

It is also positive that the proposed method is applicable to the existing practice of taxation of trees by thickness steps, which was shown in detail in our book (Mazurkin P.M., Dolgikh M.V. Component equilibrium and stability of the stand. Yoshkar-Ola: MarSTU , 2011. 164 pp.) And is briefly explained using an example from the specified book at the end of the description of the invention. For well-known taxation tables for measuring the diameters of forest trees by thickness steps, only the right side of the continuous measurement scale for this method will be applied.

A significant novelty is the measurement of the integration of the forest stand with undergrowth, undergrowth, shrubs and bushes, tree pnea and root shoots. As a result, the method allows you to form a common subsystem of the forest under the name "tree cover" or "woody vegetation". As a result, a truly part of the forest ecosystem is formed, taking into account all species and age distributions of woody plants in the selected trial area. This eliminates the narrow understanding of woody plants only as a source of wood and raises the level of forestry and forestry to a scientifically sound level.

The proposed technical solution has significant signs of novelty, a positive effect and the prospect of expanding the areas of practical application of dendrometry in environmental engineering in the component analysis of the complex phytocenosis of forest stands, as well as environmental monitoring of conservation and protection of forest areas in specially protected areas and technological monitoring in environmentally responsible growing of forest trees and forest stand in forestry.

From the scientific, technical and patent literature, materials discrediting the novelty of the proposed method were not found.

Figure 1 shows the measurement scheme of three woody plants of different sizes of the trunk; figure 2 is a table of changes in the height of the measurement depending on the measured diameter of the barrel at the lower minimum and upper maximum boundaries of the confidence interval; figure 3 shows graphs of the boundaries of the confidence interval and the formula of these graphs;

The method of measuring the butt of all trees on the trial plot of a complex stand of different ages includes such actions.

Initially, a trial plot is selected on a forest plot for measurements of all woody plants located on it, for example, for a component ecological analysis of woody vegetation. If the studied woody vegetation on the trial plot is distributed mosaic, then a territorial ecological analysis of the forest is possible.

Then, according to the sequence of measurements, the measured woody plant is selected on the trial plot, a heuristic description of the properties of the selected woody plant and its place of growth is performed. Moreover, the measurements are subsequently carried out without destroying the woody plants, that is, any individual from the vegetation on the trial plot. Therefore, the paths of the researchers are planned in advance and the outline of the test area is compiled indicating the places where trampling of forest soil is possible.

The location of the neck of the root is established on each tree plant, and at the same time, the trunk section from the root neck to the calculated height, which depends on the diameter of the trunk at the same height, is taken for the butt of a growing tree plant, and with an increase in the diameter of the trunk of the tree plant, the upper section of the butt is taken to be not less than the standard height .

To take into account all biological species of woody plants of different productivity in wood, for the butt of a woody plant, take the trunk section from the root neck to the estimated minimum and maximum heights, depending on the diameter of the trunk at the same height along the lower and upper boundaries of the confidence interval according to quantitative data from the following table :

16.0 1.0 6.0 1.0 - - 16.0 1.3

With an increase in the diameter of the trunk of a woody plant, the upper section of the butt is taken to be at least a standard height according to the formulas of the boundaries of the confidence interval:

; $${\text{h}}_{\text{D}}^{\text{min}}=\text{one}\text{, 3 (1}-\text{exp (}-\text{0}{\text{, 064732D}}^{\text{one}\text{, 12520}}\text{)))}$$

5 - large undergrowth, trees, undergrowth, large shrub (1 cm);

6 - forest trees (step thickness 2 cm);

7 - forest trees (step 4 cm thick).

To form a continuous scale for measuring the diameter of the trunk of woody plants, taking into account the accuracy of measurements by groups of values of the diameter of the trunk, measuring tools are used: 1 - micrometer; 2-4 - vernier caliper; 5-7 - measured fork.

The data are recorded in a journal and then processed to obtain tables of source data in the office environment for modeling by distributions of the diameter of the barrel and its height. If other taxation indicators of each plant from the whole woody vegetation on the trial plot are measured, then two-factor patterns of the influence of diameter and height of measurement on other parameters of woody plants are revealed by statistical modeling.

A method for measuring the lump of woody plants, for example, only forest trees, for component analysis of the formed stand by thickness steps of 8 or more centimeters according to the existing Russian forestry methodology for measuring trunk diameter at a standard height of 1.3 m, includes such actions.

Initially, a trial plot is selected on the forest plot for measuring the trees located on it, usually in future plots for calculating the volume and commodity valuation of forest tree trunks by marketability classes in the form of business and wood trees. A huge number of such measurements are performed, but environmental information is not extracted from the obtained source data tables. As a result, after cutting trees in the cutting area and selling assortments, the results of measurements and subsequent calculations are simply discarded. And they could serve, albeit once, for an environmental assessment of the component equilibrium in a cut down forest stand so that further forestry measures can achieve high production of the future forest stand.

It is especially necessary to carry out, at least on forest stands in the form of stands, a counting of trees by thickness steps at a standard height of 1.3 m in specially protected areas in order to carry out sanitary and other types of felling of renewal and reformation trees. And thus, to prevent forest lands from perishing, for example, nature reserves transferred to forest enterprises, national parks, hunting farms and other forest areas, which have ceased economic activity, in particular, harvesting of wood and other raw materials.

According to the sequence of measurements, the measured forest tree is selected on the trial plot in the form of an allotment or a future plot, a heuristic description of the properties of the selected tree and the place of its growth is performed. In this case, measurements, for example, by continuous enumeration, are carried out without destruction of the measured trees. In addition, such a simplified measurement involves ignoring the undergrowth, undergrowth, shrubs and shrubs, and shoots.

According to existing measurement methods, they have no economic value. Therefore, only adults and valuable individuals are taken into account.

On each tree, the location of the neck of the root is established, and at the same time, the trunk section from the root neck to the standard height of 1.3 m is taken for the comel of the growing tree plant, which in this simplified version of the proposed method does not depend on the diameter of the trunk. Then, the diameter values of all measured several hundred trees in office conditions are distributed according to the steps of the trunk thickness or are subjected to statistical modeling without grouping.

Example. It is adopted according to the continuous enumeration of trees from our book (Mazurkin P.M., Dolgikh M.V. Component equilibrium and stability of the stand. Yoshkar-Ola: MarSTU, 2011. 164 pp.). To assess the indicators of component equilibrium and stability of mixed pine, a specific cutting area was adopted at the Nolinsky forestry (Table 1) in the southeastern part of the Kirov region.

Table 1 Continuous counting of trees of all species on sections 12 and 1 square. 106 The degree of thickness d, cm Number of trees business N _d N _{wood, etc.} total N 8 0 0 0 12 0 0 0 16 97 22 119 twenty 75 twenty 95 24 55 fourteen 69 28 61 fourteen 75 32 one hundred eighteen 118 36 70 6 76 40 25 8 33 44 eleven 5 16 48 3 0 3 52 5 0 5 56 0 0 0 Total 502 107 609

The results of the analysis of measurements and modeling by identifying stable biotechnological patterns will be fairly reliable, but still not ideal. As a result, the example implements the proposed method only in a simplified private form.

In the table, the number of trees is grouped by steps of thickness and commodity groups. This approach is called stem wood taxation.

The number of business trees is about five times the number of wood trees, which is an indicator of the environmental situation in the area. A significant amount of 96.6% conifers, the percentage of pine to the total number of trees is 74.7%.

The maximum number of business trees of three species is 100 pcs. at a step of 32 cm. However, due to the maximum number of wood trees, the total number of 119 plants of the two status categories is at the 16 cm thickness step. The second maximum of 118 is visible at a thickness of 32 cm. The maximums in business and the total number of trees seem to change places . This is the result of external influence on the stand. The share of business trees is 100 × 502/609 = 82.43%. This indicator is applicable for comparing different stands with each other.

The coefficients of stability and instability. The sustainability coefficient K of _the stand, in our example mixed pine on the trial plot, is calculated by a simple formula

$${\text{K}}_{\text{at}}={\text{N}}_{\text{d}}\text{/ N}\text{,}\text{(one)}$$

where N _d - the number of business trees of different species, pcs.,

N - the total number of business and wood trees on the trial plot (in our example, 8.8 ha in the cutting area), pcs.

The instability coefficient To _dr forest stand by the presence of trees of wood quality is also determined by a simple formula

$${\text{K}}_{\text{dr}}={\text{N}}_{\text{dr}}\text{/ N}\text{,}\text{(2)}$$

where N _dr - the number of wood forest trees of different species, pcs.

The ratio of the number of wood trees to business trees gives a fundamentally new indicator - the coefficient K _n instability

$${\text{K}}_{\text{n}}={\text{N}}_{\text{dr}}{\text{/ N}}_{\text{d}}\text{,}\text{(3)}$$

All tree species receive the data shown in table 2.

In general, for the stand in the lower row of Table 2, we obtained the values of indicators that are applicable for comparison with other mixed stands.

The pine stability coefficient is K _y = 0.8243.

The pine instability coefficient in terms of the number of wood trees of all three species is equal to K _dr = 0.1757.

The pine instability coefficient in relation to the number of wood trees to business trunks is equal to K _dr = 0.2131.

The effectiveness of the new method is manifested in the fact that it allows you to analyze any tree communities, including the results of the existing forest taxation of the trunk diameter by large uniform thickness steps at a standard measurement height of 1.3 m.
