基于AHP-PCA模型的煤炭城市生态环境质量评价

Eco-environmental Quality Evaluation of Coal City Based on AHP-PCA Model

  • 摘要: 为了更加科学合理地评价煤炭城市的生态环境质量状况,基于生态敏感性—生态恢复力—生态压力模型,选取自然地理、土地覆盖、植被、环境污染、地表灾害和社会压力等方面的20项评价指标,采用AHP-PCA权重模型构建煤炭城市生态环境质量的评价指标体系,得到的煤炭城市生态环境质量结果表明,该方法能够客观定量地揭示出煤炭城市的生态环境质量等级和空间分布特征,评价结果符合煤炭城市的现状,对煤炭城市生态环境治理和产业规划具有重要的实用价值。

     

    Abstract: In order to more scientifically and reasonably evaluate the eco-environmental quality situation of the coal city, 20 evaluation indexes including the physiography, land cover, vegetation, environmental pollution, surface disaster, society and so on were selected based on the ecological sensitivity-resilience-pressure model, an indictor system for the eco-environmental quality evaluation of the coal city was established by using Analytic Hierarchy Process and Principal Component Analysis model. The comprehensive evaluation results of the eco-environmental quality of the coal city showed that this evaluation method can objectively and quantitatively reveal the quality level and the spatial distribution characteristics of the eco-environment quality of the coal city, the evaluation results confirmed to the current situation of the coal city, so it has important practical value for the eco-environment management and industrial planning of the coal city.
