生态环境质量评价现状分析及展望

Current Status and Prospect of Eco-environmental Quality Evaluation

针对多样性和复杂性的各类生态环境,要达到合理、精确地对其进行生态环境质量评价的目的,关键在于评价方法、评价模型的选取。文章在对层次分析法、熵权法和主成分分析法三种单独评价方法进行了利弊分析的同时,也简介三种综合评价方法的原理和优势,并从改进评价方法和进行综合评价两个方面提出改善建议。PSR模型和RSEI模型作为现行的主要评价模型,对生态环境指标体系的构建具有指导作用,依附于内在逻辑的普适性,仍具有广泛的适用性。

The selection of evaluation method and evaluation model is the key to achieve the objective of evaluating the ecological environment quality reasonably and accurately for the diversity and complexity of various ecological environments. In this paper, the advantages and disadvantages of the threeindependent evaluation methods of analytic hierarchy process, entropy weight method and principal component analysis are analyzed. The principles and advantages of the three comprehensive evaluation methods are introduced and suggestions for improvement are put forward from two aspects of improving evaluation methods and comprehensive evaluation. PSR model and RSEI model, as the current main evaluation models, play a guiding role in the construction of ecological environment index system, and are still widely applicable depending on the universality of internal logic.
