摘　　要：在阐述大黄堡湿地生态地质环境条件基础上,选取湿地水涵养状态、水文地质条件、水土环境质量、生物多样性及人类工程活动等多个评价因子,利用傅勒三角形法确定各评价因子的权重,采用综合指数法对大黄堡湿地生态地质环境脆弱性进行了综合评价。评价结果显示,大黄堡湿地可划分为生态地质环境脆弱性低区、中等区、较高区和高区4个区,其中核心区西南一带处于脆弱性低区,分布面积共为0.73 km^(2);湿地北部和南部的芦苇沼泽、上马台水库等处于脆弱中等区,分布面积共13.27 km^(2);湿地内各村镇坑塘,北京排污河、狼尔窝引河等水系处于脆弱性较高区,分布面积共68.16 km^(2);大黄堡湿地东部与南部水产养殖区以及村镇居民区等处于脆弱性高区,分布面积共29.84 km^(2)。Based on the description of the Dahuangbao Wetland and the surrounding ecological geological environmental conditions,this paper studies multiple evaluation factors such as wetland water conservation status,hydrogeological conditions,water and soil environmental quality,biodiversity,and human engineering activities,etc.It uses Fuller triangle to define the factor weight and uses the comprehensive index method to comprehensively evaluate the fragility of the ecological geological environment of the Dahuangpu Wetland.The result shows that the whole region can be divided into four grade vulnerability sections,which are the serious vulnerability section,the high vulnerability section,the medium vulnerability section and the low vulnerability section.The southwestern area of the core area of the Dahuangpu Wetland is in the low vulnerability section,adjacent to the Liuhe canal in the east,with a total distribution area of 0.73 km^(2).Reed swamp wetland patches in the north and south of Dahuangbao Wetland and Shangmatai Reservoir are located in the medium vulnerability section,with a total distribution area of 13.27 km^(2).Ponds in villages and towns in Dahuangpu Wetland,Beijing Sewage River,Langerwo irrigation channel are located in the high vulnerability section,most of the wetland belongs to this area,with a total distribution area of 68.16km^(2).Aquaculture areas in the east and south of Dahuangpu Wetland and residential areas in villages and townsare located in theserious vulnerability section,with a total distribution area of 29.84 km^(2).
