蠡湖增殖放流适宜地评价*

 以蠡湖可持续健康发展为前提，建立了蠡湖增殖放流适宜地评价体系，包括1个总目标，4个分目标和15个具体指标。应用主成分分析法筛选因子，结合利用层次分析（AHP）法和鱼骨图法确定权重，并利用地理信息系统（GIS）栅格模块和分级模块，完成蠡湖增殖放流适宜地的等级评定。结果表明：蠡湖增殖放流适宜地评价为最高等级的区域面积为0.4005km2,蠡湖增殖放流适宜地评价为较高等级的区域为6.0075km2，蠡湖增殖放流适宜地评价为高等级的区域面积为1.2015km2，蠡湖增殖放流适宜地评价为一般等级的区域面积为0.3204km2和蠡湖增殖放流适宜地评价为低等级的区域面积为0.0801km2。蠡湖增殖放流适宜地评价等级图为蠡湖的科学规划和管理提供参考依据。

Evaluation of Suitable Land of Enhancement and Release in Lihu Lake

The system of evaluation of suitable land of enhancement and release in Lihu was established based the precondition of sustainable development of Lihu.It included one overal objective, 4 sub objectives, and 15 indices.Principal component analysis was applied to facors selection, analytic hierarchy process (AHP) and fishbone diagram were synthetically used to calculate weight, and the model of raster and classification of GIS were used to finish the ranking map of evaluation of suitable land of enhancement and release in Lihu.The result showed that:suitable land of enhancement and release in Lihu was divided into 5 grades in term of highest, higher, high, general and low, and which covered 0.4005, 6.0075, 1.2015,0.3204 and 0.0801 square kilometer respectively. The study provides reference for plan and management to administrant department.
