Abstract

The invention discloses a natural reserve ecological environment evaluation method based on a high-resolution remote sensing image, and the method comprises the steps of constructing natural reserve ecological environment evaluation indexes which comprise a first-level index and a second-level index, wherein the first-level index comprises an ecological system pattern, a climate response system and human activity ecological stress; the secondary indexes included in the ecosystem pattern comprise a landscape diversity index, a landscape aggregation degree index, a landscape connectivity index and an ecological land area proportion; the climate response system comprises secondary indexes including annual precipitation, average surface temperature and vegetation coverage; and secondary indexes included in the human activity ecological stress comprise a comprehensive human disturbance index and pollution gas emission; the method further includes performing grade division and weight division on the evaluation indexes; and constructing an evaluation model based on the grade assignment and the weight to obtain the ecological environment quality grade of the natural reserve. The inventioncan achieve the quick evaluation of the ecological environment quality of the natural reserve, and facilitates the quick mastering of the ecological environment condition of the natural reserve.

Description

technical field [0001] The invention relates to the technical field of nature reserve evaluation, and more specifically relates to a method for evaluating the ecological environment of a nature reserve based on high-resolution remote sensing images. Background technique [0002] Nature reserves are based on representative regional natural ecosystems, rare and endangered wild animal and plant species, special significance natural relics, and other land and water areas where special protection objects exist, and delineate a certain area for special protection and management. It is an important carrier for countries to promote the construction of ecological civilization and build a national ecological security barrier, which is of great significance to human survival and well-being. [0003] However, in the past 30 years, due to the impact of climate change, population growth and human development, coupled with poor management of protected areas and the absence of conservation ...
