Embodiment 1
[0039] Embodiment 1 A kind of North China larch (Larix principis-rupprechtii) plantation density configuration method based on soil moisture and vegetation carrying capacity
[0040] A kind of North China larch plantation density configuration method based on soil water vegetation carrying capacity, comprising the following steps:
[0041] 1) Determine the soil effective water capacity under the specific site conditions of the slope;
[0042] 2) Determine the relationship between the annual evapotranspiration of a specific stand and its annual maximum leaf area index (LAI);
[0043] 3) Determine the relationship between soil thickness and LAI under specific site conditions;
[0044] 4) According to the relationship between stand LAI and its density, calculate the reasonable stand density.
[0045] The method for determining the soil effective water capacity of the North China larch plantation land in the half shade slope 1) is:
[0046] A=(F-W)×T=0.3527×T (1)
[0047] In t...
Embodiment 2
[0061] A method of tiger hazel (Ostryopsis davidiana) bush cover configuration based on soil moisture and vegetation carrying capacity
[0062] A method for configuring the coverage of tiger hazel bushes based on soil moisture and vegetation carrying capacity, comprising the following steps:
[0063] 1) Determine the soil effective water capacity under the specific site conditions of the slope;
[0064] 2) Determine the relationship between the annual evapotranspiration of a specific shrub and its maximum leaf area index (LAI) in a year;
[0065] 3) Determine the relationship between soil thickness and LAI under specific site conditions;
[0066] 4) According to the relationship between shrub LAI and its coverage, calculate the reasonable shrub coverage.
[0067] The method for determining the effective water capacity of the soil in the Yangpo tiger hazelnut irrigation forest land in the described step 1) is:
[0068] A=(F-W)×T=0.3258×T (6)
[0069] In the formula, A is th...
