Embodiment Construction

[0013] The preferred embodiment of the spatial configuration method of the water conservation forest in the reservoir catchment area of ​​the present invention is to use the landscape ecological planning method to design the spatial pattern of the water conservation forest in the reservoir catchment area, including water conservation in the reservoir catchment area. Horizontal and three-dimensional configurations of forest species.

[0014] In the spatial layout design, at least one of the following indexes is selected as the quantitative index:

[0015] Landscape diversity index, dominance index, uniformity index, landscape separation index, fractal dimension of inlay, fragmentation index of inlay shape, fragmentation index of inlay number;

[0016] Let pi be the proportion of the i-th type of mosaic in the landscape of the study area to the total area of ​​the landscape, p1 to pm are arranged from small to large; m is the total number of mosaics in the landscape of the study...

Abstract

The invention discloses a space preparation method of a reservoir water-collection area water conservation forest. The landscape ecology programming method is used for designing the space configuration of the reservoir water-collection area water conservation forest. The landscape diversity index, dominance index, evenness index, landscape separation index, fractal dimension of wedging body, breakage index of wedging body shape, breakage index of wedging body number are used as quantification indexes and the horizontal arrangement and solid arrangement of the reservoir water-collection area water conservation forest is designed. The space configuration and structure of the water conservation forest of the reservoir water-collection area are designed, thus the water-source protection function of water conservation forest is exerted to the greater limit.

Description

technical field [0001] The invention relates to an afforestation technology in forestry science, in particular to a spatial configuration method of a water source conservation forest in a water collection area of ​​a reservoir. Background technique [0002] According to the natural and geographical conditions, we can establish a comprehensive forest system and achieve a reasonable forest coverage rate for each forest species and their configuration, as well as obtain good technology for the structure and configuration of water conservation forest belts, tree species selection, and forest management techniques. Effect. [0003] In the existing technology, through the analysis of the occurrence and development of disaster types and the degree of damage in different areas, especially in areas with severe disasters; the site classification and site evaluation of different areas where water source forests are built; the ecological benefits of water source conservation forests, es...
