Ecological risk assessment method for nature reserve

Abstract

The invention provides an ecological risk assessment method for a nature reserve. The ecological risk assessment method comprises the steps of S1, identifying ecological risk types of the natural reserve and constructing evaluation indexes of different types of ecological risks; S2, respectively calculating the weight of each evaluation index corresponding to different ecological risks of the natural reserve by adopting a mean square error weighting method, and metering the weight of the natural reserve harmed by different ecological risks; S3, visually evaluating the ecological risk indexes of different types of ecological risks of the natural reserve by adopting a GIS software platform to obtain an ecological risk index spatial distribution pattern diagram of different types of ecological risks; and S4, multiplying different types of ecological risk indexes of the natural reserve by the hazard weight of the ecological risk indexes on the GIS platform to obtain a comprehensive ecological risk index of the natural reserve, and grading the risk indexes to obtain a comprehensive ecological risk grading graph of the natural reserve. The method has the advantages of being accurate, scientific, comprehensive, systematic, wide in application range and the like for the ecological risk of the natural reserve.

Description

technical field [0001] The invention relates to an ecological risk assessment technology, in particular to an ecological risk assessment method for nature reserves. Background technique [0002] The ecological risk assessment of nature reserves is the basis of the research on the environmental safety of nature reserves and the necessary prerequisite for the targeted implementation of environmental management of nature reserves. Natural reserves are a necessary prerequisite for maintaining regional species diversity, maintaining the service functions of regional natural reserves, and ensuring the coordinated development of regional economy, society, and resources and the environment. The direct or indirect damage to nature reserves caused by human social activities is an important reason for the decline in the area and quality of nature reserves. Therefore, the ecological risk assessment of nature reserves is essential. At present, the environmental management department of...

AI Technical Summary

Problems solved by technology

At present, the environmental management department of nature reserves in my country does not involve in the assessment of the risk type, intensity and harmful effect that human activities may cause on nature reserves in the regulatory system and policy formulation process of nature reserves, which leads to the general lack of regulatory measures for nature reserves Problems are targeted and spatially indicative, so that the formulation of regulatory countermeasures for nature reserves lacks forward-looking and predictability, and it is difficult to achieve precise ecological supervision of nature reserves
