摘    要:目的]利用GIS技术对蠡湖的渔产潜力进行科学的评价。方法]根据湖泊渔产特点和相关资源,采用层次分析法和GIS技术建立综合评价蠡湖渔产潜力的数量化方法,该评价体系包括水质条件、生物多样性和水文条件等3个层次的10个指标。通过咨询专家并构建判断矩阵,确定选择因子对于渔产潜力评价的贡献率,利用ARC/INFO软件内嵌的栅格数据分析模块生成单因子评价图层,结合栅格计算、空间叠加和分级模块,得出蠡湖渔产潜力等级的分布图。结果]渔产潜力评价为较高等级的区域面积为2.6433km2、渔产潜力评价为高等级的区域为3.8448km2、渔产潜力评价为一般等级的区域面积为1.1214km2和渔产潜力评价为低等级的区域面积为0.4005km2。结论]该研究为蠡湖的生态重建提供了理论依据。

Abstract:Objective] The paper was scientifically evaluate the potential fishery productivity of Lihu using GIS technology.Method] The evaluation of potential fishery productivity in Lihu was based on GIS and AHP according to the characteristics of fisheries resources in Lihu Lake.The evaluation system included 3 sub-models including water quality,biodiversity and hydrological condition,which totally had 10 indexes.Judgment matrix was constructed based the advices of professors of fisheries resources,and the indicator’s weight were calculated by the process of AHP.The ranking distributing map of potential fishery productivity in Lihu was obtained by the model of raster analysis,raster calculator,spatial overlay and classification models of ARC/INFO.Result] Potential fishery productivity of Lihu was divided into 4 grades in term of higher,high,general and low,and which covered 2.643 3,3.844 8,1.121 4 and 0.400 5 hm2,respectively.Conclusion] The study provided theoretical basis for ecological reconstruction of Lihu Lake.
Keywords:Potential fishery productivity  Evaluation  GIS  Lihu
