Embodiment Construction

[0015] A method for measuring the spatial environmental effects of forest vegetation is different from existing methods, specifically in that:

[0016] 1) Select the appropriate scale value a, design a×a=a 2 is the research space of the grid;

[0017] 2) Determine the forest vegetation coverage value C of each grid by means of remote sensing image data extraction or ground survey i and biomass value W i , forest vegetation includes trees, shrubs, vegetation, crops, etc.;

[0018] 3) Obtain the value q of each grid environment parameter, the environment parameters include: PM 2.5 , PM 10 , temperature, humidity, rainfall, negative oxygen ions, SO 2 , HF, C1 2 equal factor;

[0019] 4) Build a model q=∑C i W i d r (r≤-1), and determine the value of forest vegetation spatial environmental effect index r;

[0020] 5) The model determined in step (4) can be directly used to determine the value of a certain environmental factor.

Abstract

The invention relates to a calculating and measuring method for space environment effect of forest vegetation. The calculating and measuring method comprises the following steps: designing a research space taking a proper scale value as a grid; establishing a forest space effect model; determining the parameter values in the model by means of extraction of remote sensing image data or ground survey; calculating the vegetation space effect of a research area according to the model. According to the calculating and measuring method, the defects that space environment effect data of the forest vegetation are difficult to acquire, the quantified calculation and measurement is difficult to realize, and research on environment factors is simplex are overcome; the efficiency and precision are improved; accurate measurement on the vegetation environment effect with multi-factor environment parameters is realized.

Description

1. Technical field [0001] The invention relates to a method for measuring the spatial environment effect of forest vegetation, in particular to a method for measuring the spatial effect of forest vegetation based on a grid method and a multi-directional method. 2. Technical background [0002] It has become a consensus in today's society that forests have three major benefits: economic benefits, ecological benefits, and social benefits. However, the quantitative research on the spatial environmental effects produced by a tree or a piece of vegetation and how it spreads in space has always been an international problem. In recent years, my country and Beijing have attached great importance to the construction of the ecological environment and achieved remarkable results. However, it is still difficult for these forests to guarantee their effectiveness in improving the negative effects brought about by the deterioration of the ecological environment. How to create vegetation s...
