Description
Technical field
The utility model relates to forestry, botany and ecological study field, specifically a kind of trees radial growth monitoring device.
Background technology
Quantize exactly arboreal growth speed, not only can analyze the growth rhythm of seeds, the dynamic change of research forest biomass, yield-power and accumulation, can also carry out correlation analysis with meteorological data, seeks the impact of environmental change on trees yield-power.By standard measurement tools, as assize diameter of a cross-section of a tree trunk 1.3 meters above the ground chi, the diameter that trees are measured at the 1.3m place that makes progress on ground is current universal method.And by trees radial growth monitoring devices (abbreviation growth ring) are installed, trees radial growth is carried out for a long time, located, continuously, accurately measurement is subject to increasing attention.But, there is following shortcoming in conventional growth ring: first growth ring measurement window is difficult to control, because the difference of individual trees diameter need to be calculated according to the diameter of target individual the size of estimating measurement window by formula, the labour intensity that increases installation personnel, has reduced work efficiency; Secondly, growth ring is just attached to tree around, easily comes off, and after coming off, is difficult for returning to origin-location, and before and after causing, data can not be mated, and affect measurement accuracy.
Utility model content
The measurement window control difficulty, the caducous problem of growth ring that in order to solve existing growth ring, exist, the purpose of this utility model is to provide a kind of trees radial growth monitoring device.
The purpose of this utility model is achieved through the following technical solutions:
The utility model comprises mounting strap and spring, and wherein the two ends of mounting strap are connected by described spring, and by the elastic force of described spring, is connected to the trunk surface of monitored trees, is the measurement window of monitoring trees radial growth between the two ends of described mounting strap.
Wherein: the two ends of described mounting strap have the hole being connected with spring, arbitrary end of described mounting strap is fixed on the trunk of monitored trees by drawing pin; The overall length L of described mounting strap is that the girth of described trunk deducts 10cm; Distance between described mounting strap two ends, be that the length of described measurement window increases with the radial growths of monitored trees.
Advantage of the present utility model and good effect are:
1. the utility model is installed fast, be connected closely with monitored trees, and difficult drop-off, monitoring variable data are more accurate.
The utility model simple in structure, save material, measure conveniently, greatly improved sampling efficiency, can realize the object of long-term, location and Real-Time Monitoring.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
Fig. 2 is the structural representation of the utility model mounting strap;
Fig. 3 is that the utility model is arranged on the working state figure on trunk;
Wherein: 1 is mounting strap, 2 is spring, and 3 is measurement window, and 4 is trunk, and 5 is A hole, and 6 is B hole, and 7 is C hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figures 1 to 3, the utility model comprises mounting strap 1 and spring 2, and wherein the material of mounting strap 1 can be stainless steel, is shaped as strip; Arbitrary end of mounting strap 1 has A hole 5 and B hole 6 along its length, and the other end has C hole 7, and this C hole 7 is arranged symmetrically with A hole 5; Distance L 1 between the A hole of the present embodiment and C hole and mounting strap 1 end, two ends is 5mm, and the distance L 2 between A hole and B hole is 20mm.The two ends of mounting strap 1 are connected by spring 2, and by the elastic force of spring 2, are connected to trunk 4 surfaces of the monitored trees of selected good installation site, and the overall length L of mounting strap 1 is that the girth of trunk 4 deducts 10cm.A hole on mounting strap 1 and C hole are the tie point with spring 2, and B hole is for being fixed on one end drawing pin of mounting strap 1 the drawing pin point of fixity on the trunks 4 of monitored trees.Between the two ends of mounting strap 1, be the measurement window 3 of monitoring trees radial growth, the length of this measurement window 3 (being the distance between mounting strap 1 two ends) increases with the radial growth of monitored trees.
Principle of work of the present utility model is:
On the trunk 4 of monitored trees, select behind good installation site, first with file, remove exocuticle, with drawing pin, one end of mounting strap 1 is fixed on again to the surface of trunk 4, the other end was wound around trunk after 4 one weeks, and between described one end, form the measurement window 3 of a 5～15cm, by spring 2, connect, utilize spring 2 mounting strap 1 to be tightly fitted in to the surface of trunk 4, trunk 4 growth meeting stretching measurement window 3, by the big or small change conditions of this measurement window 3 of vernier caliper measurement, reflect the growth change situation of tree diameters.
