Abstract

The invention discloses a vegetation ecological quality index construction method based on vegetation NPP and coverage. The method includes: according to the climate adaptability principle of vegetation growth and the importance of ecological service functions, on the basis of calculating vegetation NPP and coverage, calculating an annual vegetation comprehensive ecological quality index of a local or concerned area by weighting the weight; calculating the ratio of the current-year vegetation NPP to the historical highest value; determining the weight of the vegetation NPP and the coverage inthe comprehensive ecological quality index; converting the current-year vegetation NPP is converted from gram carbon/square meter * year to a ratio of relative historical highest values, wherein the value is between 0 and 1; and matching the vegetation coverage with the numerical value of 0-1. The problem of comprehensively and quantitatively calculating the vegetation ecological quality is solved, the method is more objective and comprehensive compared with single use of vegetation NPP or coverage quantitative expression vegetation ecological conditions, the method is suitable for estimationof the vegetation ecological quality of the whole land ecological system, and important technical support is provided for monitoring and evaluating the vegetation ecological quality and developing ecological meteorological services.

Description

technical field [0001] The invention relates to a vegetation ecological quality index model, in particular to a vegetation ecological quality index construction method based on vegetation NPP and coverage. Background technique [0002] Vegetation net primary productivity (NPP) and vegetation coverage are the two most basic service functions of terrestrial ecosystems, which have been extensively studied at home and abroad. However, at present, the research and application of its separate estimation method are basically focused on at home and abroad, and there are few models and methods based on the two estimation methods for estimating the overall ecological quality of vegetation. In fact, the level of vegetation ecological quality in a place cannot be expressed by only one of vegetation NPP or vegetation coverage, but also needs to comprehensively reflect the level of its vegetation ecological quality. [0003] At present, the research focus of existing technologies is how ...
