Embodiment Construction
[0029] Below in conjunction with accompanying drawing and example, the present invention is described in further detail.
[0030] The control methods of rocky desertification are mainly closed hills for afforestation and grass cultivation, artificial afforestation, etc. Therefore, "vegetation coverage + leaf area index" can be combined to quantitatively and systematically evaluate the effectiveness of rocky desertification control. Specifically, from the perspective of vegetation coverage and physiological conditions, the present invention constructs a multi-index evaluation system based on vegetation coverage and leaf area index, systematically evaluates the implementation degree and effectiveness of rocky desertification control, and solves the problem that the current single index is difficult to systematically reflect rocky desertification. governance effectiveness and other issues.
[0031] Among them, the vegetation coverage (FVC) refers to the ratio of the vertical proj...
