Ecological environment quality evaluation method and device

Abstract

The embodiment of the invention provides an ecological environment quality evaluation method and device, and belongs to the technical field of ecological environments. The method comprises the following steps: calculating vegetation net primary productivity, vegetation coverage and geographic distribution based on remote sensing information; calculating potential vegetation net primary productivity, potential vegetation coverage and potential geographic distribution based on meteorological conditions;calculating actual and potential vegetation ecological quality of vegetation net primary productivity, vegetation coverage and geographic distribution based on remote sensing information and meteorological conditions; calculating the actual vegetation ecological quality variation based on theremote sensing information and the potential vegetation ecological quality variation only considering the meteorological condition change influence; and calculating a meteorological contribution rateand a human factor contribution rate of the vegetation ecological quality change. According to the embodiment, the ecological civilization construction performance of nationwide scale, provincial scale, county scale and any evaluation area in different time periods can be evaluated, and meteorological condition contribution rate evaluation and thematic map manufacturing of the ecological civilization construction performance can be carried out.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of ecological environment, and in particular to a method and device for evaluating the quality of the ecological environment. Background technique [0002] The construction of ecological civilization is an important project to promote the improvement of the quality of the ecological environment. At present, the quality changes of the ecological environment are affected by both meteorological conditions and human conditions. Meteorological conditions and the impact of human activities on the ecological environment are often entangled and difficult to separate. In related technologies, when evaluating the quality of the ecological environment, it is mainly based on climatic factors and remote sensing information. evaluate the relationship between them. However, changes in the quality of the ecological environment are not only subject to natural factors such as climate, but also to h...

Problems solved by technology

Existing climate models and remote sensing inversion models cannot distinguish and quantify climatic factors and human factors in the change of ecological environment quality, so the evaluation results are not accurate enough
