摘要
生态地质环境质量评价,实为生态地质环境的适宜性评价。本文以地貌类型、森林覆盖率、人口密度等16个指标为主要影响因子,确定了生态地质环境质量评价指标的单因素评价模型和评价指标体系。采用模糊数学方法,对阜新市生态地质环境质量进行了综合评价。结果表明阜新地区生态地质环境质量总体良好。经验证,定量评价与定性评价结果较吻合,证明该套基于模糊综合评判技术的生态地质环境质量的定量评价是切实可行的,结论是可信的。
The quality evaluation of geoecological environment is actually the geoecological environment＇s suitability evaluation. This paper uses landscape types, forest cover, population density and so on （in all 16 indicators） as the main factors to determine the quality of geoecological environment, then indicators single factor evaluation model and evaluation index system, Geoecological environment quality of Fuxin was evaluated by fuzzy mathematical method, The results showed that the geoecological environment quality of Fuxin region is generally good. The fuzzy judge way is applied to evaluation, and fuzzy mathematical method is effectively adopted in picking up （indication） value and making chart. Through verification, these evaluation systems are viable,
