Natural preservation area management effectiveness quantitative evaluation method and system

Abstract

The invention discloses a method and a system for quantitatively evaluating natural preservation area management effectiveness. The method comprises the following steps: obtaining environmental and ecological data of a natural preservation area by measures such as a remote sensing satellite and field survey and the like, determining a natural preservation area management effectiveness quantitative evaluation indexes system by utilizing an analytic hierarchy process and an expert scoring method, determining index intension and a quantitative measuring method of the index intension so as to be convenient for quantitative evaluation of the future preservation area; conducting inversion to index values of NPP (net primary productivity), vegetation coverage, a typical habitat dominance and habitat degradation indexes and the like by utilizing the remote sensing data; measuring management measures and social impact rule layer correlation indexes by utilizing ground investigation data; determining all index permissions by utilizing the analytic hierarchy process, and conducting weighting summation to measure all natural preservation area evaluation values; and determining an evaluation criterion, and conducting evaluation grading to the natural preservation area based on the standard. In the invention, the natural preservation area evaluation quantitative performance and representativeness are realized, so as to be beneficial to realization of on-line evaluation to the natural preservation area subsequently according to the category of the natural preservation areas.

Description

technical field [0001] The invention relates to the technical fields of ecological environment protection and remote sensing, in particular to a method and system for quantitatively evaluating management effectiveness of nature reserves. Background technique [0002] With the development of nature reserves in my country, higher requirements are put forward for the management of nature reserves, and a set of scientific, easy-to-acquire, and quantitative management effectiveness evaluation index system is urgently needed to evaluate the management effectiveness of nature reserves. nature and science. [0003] At present, most researchers use WB / WWF tracking tools and other methods to divide the evaluation indicators into several state descriptions, and assign certain scores from poor to excellent (or poor to excellent), so that qualitative problems can be converted into quantitative assignments. Then calculate the total score, and then evaluate the effectiveness of protected a...

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that the traditional evaluation index system has at least the following technical defects: the quantification of the index is relatively artificial; the ecological function feedback protection effect is insufficient in the evaluation of management effectiveness

The reason is that the traditional qualitative evaluation model is easier to implement, and more evaluation indicators focus more on the evaluation of management methods, focusing on short-term management effectiveness

However, the management effectiveness of nature reserves should reflect long-term benefits. If the ecological functions and species resource protection effects are not reflected in the management effectiveness evaluation, it may lead to short-term effects and discontinuity in the evaluation results; if there are more human factors, May lead to inaccurate evaluation results

so as not to achieve the purpose of evaluation
