Woods working group and the matching process of bottom class specifically include:
Step 101: obtaining the working group judgment matrix in region locating for forest management unit.
For a forest management unit (such as forest farm), different Forest management types only implement to specific small
Class is just able to achieve the transformation from theory and technology to practical operation.Bottom class is the minimum list for carrying out orest management, tissue wood producing
The basic unit of position and Investigation and Design.It is in operation area that land occupation condition, stand facters, the style of cutting, Operation Measures are identical
A bottom class is divided into the standing forest of logging systems compliant.Bottom class's boundary is by logging system based on natural regionalization.One bottom class
Area is generally advisable with 5 hectares or so, and maximum is not to be exceeded 20 hectares.
Forest management types should be the set of multiple orest management units (bottom class), these orest management units should have
There are same or similar operations objective (seed of forest), same or similar land occupation condition (height above sea level, thickness of soil, humus, the gradient
Deng), same or similar stand characteristics (age group, density, composition).According to " (2016- is planned in national orest management
2050) ", for a certain tree species X, what Forest management types can be concise is expressed as " the X+ seed of forest (the sub- seed of forest)+operator
Formula ", and the seed of forest (the sub- seed of forest) and the corresponding relationship of operation mode may be expressed as:
The corresponding relationship of 1 seed of forest of table (the sub- seed of forest) and operation mode
For example, if it is Commercial Forests (seed of forest), working group includes: poplar+fast-growing, high-yield woods for poplar
(the sub- seed of forest)+general clear cutting system method, poplar+general Timber stands (the sub- seed of forest)+shetterwood strip system etc.；If it is public good
Woods, working group type include: poplar+forests for water and soil conservation (the sub- seed of forest)+alliance shape selection method；Poplar+scenic forest is (sub-
The seed of forest)+protection operation working system etc..
It, can be by the sub- seed of forest (7 kinds of shelter-forest, special type according to corresponding relationship shown in upper table 1 in the case where tree species X is determined
7 kinds of purposes woods, 3 kinds of Timber stands, a kind of firewood forests, 5 kinds of economic forest) and working system (7 kinds) be combined into a variety of forests of the tree species X
Working group.Wherein working system include general clear cutting system method, inserted clear cutting system method, shetterwood strip system, umbrella gradually
It cuts down working system, alliance shape selection method, single tree selection method and protection and manages 7 kinds of working system.Shelter-forest includes water source
Self-restraint woods, forests for water and soil conservation, forests for windbreak and sand-fixation, farmland Protective Forest in Rangeland, protective belt along an embankment, protective belt along a road and totally 7 kinds of other shelter-forests；
Forest for special purpose include forests for national defence, experimental forest, seed forest, environmental protection forests, scenic forest, the scenic spots and historical sites and revolution memorial forest, from
Right totally 7 kinds of woods of protection zone；Timber stands includes short circulation phase raw material of industry Timber stands, fast-growing and high-yield timber forest, general Timber stands totally 3
Kind；Economic forest includes fruit tree woods, edible raw material woods, woods chemical industry raw material forest, Medical forests, totally 5 kinds of other economic forests.
As the land occupation condition (height above sea level, thickness of soil, the gradient) and standing forest condition (age group, density where target tree species X
And composition) difference, in the case where the seed of forest determines, the operation of target tree species X of land occupation condition and standing forest conditional decision
Type and recent Operation Measures.
In the present invention Rule of judgment of working group be ai (i=1,2 ... n), bj be condition ai grade (j=1,
2 ... m), and the land occupation condition and standing forest condition where the tree species X determine the judgement square of the K kind working group of tree species X
Battle array:
Wherein XaibjFor judgment matrix XKThe element of i-th row jth column；Wherein ai indicates to judge for i-th the factor, i=1,2 ...
N, n are the quantity for judging the factor；Bj expression judges j-th of grade of the factor, and j=1,2 ... m, m are the number of degrees for judging the factor
Amount.
Specifically, as shown in Fig. 2, in the embodiment of the present invention, select height above sea level, thickness of soil, 3 land occupation conditions of the gradient and
3 age of stand, density, composition standing forest conditions are used as and judge factor i, therefore n=6.Its intermediate altitude, thickness of soil, the gradient 3
In land occupation condition:
Height above sea level be divided into high (>=800m), in (400m~800m), low (≤400m) 3 grades；
Thickness of soil be divided into thick (>=60cm), in (30cm~60cm), thin (≤30cm) 3 grades；
The gradient is divided into steep (>=25 °), slow (5 °~25 °), flat (≤5 °) 3 grades.
The age of stand, density, in tree species this 3 standing forest conditions:
The age of stand be divided into children (≤20a), nearly (20~30a), at crossing (>=30a) 3 grades；The age of stand, unit a represented year；
Density is divided into height (>=2500n/hm2), in (1000~2500n/hm2), low (≤1000n/hm2) 3 grades；
Composition is divided into that pure (a certain composition ratio >=80%), half mixed (a certain composition ratio is between 50%
Between~80%) and a kind of 3 grades of mixed friendship (without composition ratio >=50%).
The regional climate characteristics as locating for different operating units are managed degree and are had differences early period, and specific grade scale can
It is determined according to operating unit's actual conditions.
Therefore in the embodiment of the present invention, if a1 is height above sea level, a2 is thickness of soil, a3 is the gradient, a4 is age group, a5 is close
Degree, a6 be composition (Factors of a can also increase according to the actual situation certainly, equally can in judgment matrix table
It states)；If b1 be each judgement height of the factor, thickness, it is steep, at cross, the biggish grade of values, the b2 such as close, pure are grade placed in the middle, b3 is to take
It is worth lesser grade, i.e., the grade quantity m=3 of each judgement factor.
Therefore for a certain tree species X (such as poplar), existing land occupation condition and standing forest condition can use XaibjCarry out table
Show, wherein i=1,2,3,4,5,6；J=1,2,3, the matrix of composition is the judgment matrix of tree species X:
Then the corresponding working group decision condition of tree species X can be write: High aititude+BC soil thickness+abrupt slope+
The combination of Fast-growth phase+high density+pure forest (a1b1+a2b2+a3b1+a4b3+a5b1+a6b1).
Step 102: obtaining bottom class's observing matrix of the forest management unit.
For the bottom class of the forest management unit, the land occupation condition and standing forest condition of locating bottom class can use Yaibj'
It indicates, i ∈ { 1,2 ... n }, j ∈ { 1,2 ... m }.N=6 in the embodiment of the present invention, m=3.
Set that a1 as height above sea level, a2 is thickness of soil, a3 is the gradient, a4 is age group, a5 is density, a6 is groups of tree species in the present invention
At (Factors of a can also increase according to the actual situation certainly, can equally state in observing matrix).Due to item in bottom class
The value of the part factor is specific value, and grade can state b1 ', b2 ', b3 ', grade sequence standard same b1, b2, b3 as.
If Yaibj'For the ai factor of bottom class Y, (i=1,2,3 ... 6) bj ' a grade point (j=1,2,3) are then small
The observation matrix of class's Y criterion are as follows:
Y=[Ya1bj' Ya2bj' ... Yanbj'] (3)
Wherein Yaibj'J-th of grade point of the factor is judged for i-th for the Y bottom class, i ∈ { 1,2 ... n }, j ∈ 1,
2,…m}。
Then in the embodiment of the present invention, observing matrix Y are as follows:
Y=[Ya1bj',Ya2bj',Ya3bj',Ya4bj',Ya5bj',Ya6bj'] (4)
The conditional combination of bottom class Y can be write: High aititude+BC soil thickness+abrupt slope+Fast-growth phase+high density+pure forest
The combination of (a1b1 '+a2b2 '+a3b1 '+a4b3 '+a5b1 '+a6b1 ').
Step 103: bottom class and working group are determined according to the working group judgment matrix and bottom class's observing matrix
Distance.
The observing matrix obtained using the specific factor information of bottom class, judges the shortest distance of bottom class Yu target working group K.
If wiThe weight of the factor is judged for i-th, then the specifically on the spot k-th orest management with standing forest condition and tree species X of the Y bottom class
The distance value L of typeYKAre as follows:
During the present invention is implemented:
LYKIt is the Y bottom class at a distance from the K kind working group of the tree species X.Since different factor dimensions are different, institute
To seek calculation distance LYKBefore, the grade point to all factors carry out the normalized of dimension.
The judgement factor ai ai factor relevant to working group in bottom class Y is identical, and difference is judgment matrix XKIn
The value of grade bj is defined number value or range, and the grade bj ' in bottom class's Y observing matrix is specific numerical value, so
When calculating bottom class occurrence b1 ', b2 ', b3 ' by formula (5) or (6) at a distance from b1, b2, b3, b1 is taken respectively in calculating
Judge to be arranged in the larger rate range of the factor equivalence (i.e. height above sea level take 800m, thickness of soil to take 60cm, the gradient take 25 °, the age of stand takes
30a, density take 2500n/hm2Etc.), b2 takes each intermediate value for judging factor rate range placed in the middle, and (i.e. height above sea level takes 600m, soil
Thickness take 45cm, the gradient take 15 °, the age of stand take 25a, density to take 1750n/hm2Etc.), b3 takes each judgement factor smaller respectively etc.
Grade range in be arranged equivalence (such as height above sea level take 400m, thickness of soil take 30cm, the gradient take 5 °, the age of stand take 20a, density to take
1000n/hm2Etc.).
Judge the weight w of factor ai for i-thiJust refer to factor ai to judge its for the importance of specific working group,
Such as during water and soil conservation public good forest zone judges that bottom class Y becomes working group K, what the importance of height above sea level and the gradient accounted for
Specific gravity is higher than the importance of the other conditions factor, then the weight of height above sea level and the gradient is bigger.
Distance matrix LYKBefore calculating, the grade point needs of each factor are normalized, to realize cancellation dimension, and
The different factors have additive property.
