%X 根据地表水资源脆弱性内涵及保定市地表水资源的特点, 从自然脆弱性、人为脆弱性和承载脆弱性三个方面 选取 10 项评价指标。利用层次分析法确定各指标权重, 基于综合指数法结合 GIS/ RS 技术对保定市地表水资源脆 弱性进行了定量评价。结果表明, 保定市地表水资源总体上呈现出较为脆弱的态势, 其中以保定市西北部、西部、中 部偏东及东南部地区表现得最为明显。根据脆弱性结构, 将这些地区分成自然脆弱性主导型地区、人为脆弱性主导 型地区和承载脆弱性主导型地区三类。针对自然和人为脆弱性主导型地区, 提出加快水利设施建设、扩大绿化面积 等对策; 针对承载脆弱性主导型地区, 提出控制用水总量和人口增长、淘汰落后产能、发展节水技术、宣传节水知识 等对策。  Acco rding to the connotatio n of surface w ater resour ces vulnerability and the characteristics o f surface water r eso urces in Baoding, 10 evaluatio n indexes are selected fr om three aspects: natural vulnerability, human vulnerability and burden v ulner a2 bility . T he w eig ht o f each index is calculated by AH P, and the vulnerability o f surface w ater resour ces is quantitat ively ev aluated by comprehensiv e index method and GIS/ RS technolog y. T he r esults show that the surface w ater r eso ur ces in Bao ding are gen2 er ally v ulner able, and t he mo st v ulnerable ar eas ar e the northwestern, western, east2cent ral, and so ut heastern parts of Baoding . Accor ding to the vulner ability structure, these ar eas are div ided into three cat eg ories: natur al v ulnerability2dominant a reas, hu2 man vulnerability2dom inant areas and burden v ulner ability2dominant a reas. Fo r the natural v ulner ability2dominant and human vulnerability2dominant areas, some countermeasures ar e put forw ar d such as construction of w at er co nser vancy facilities and ex2 pansion of aff orestation ar ea; for the burden vulner abilit y2dominant ar eas, this paper pr oposes contro lling water co nsumption and po pulat ion g row th, eliminating backwar d pr oductio n capacity, dev elo ping water2sav ing techno lo gies and promoting water2saving know ledge.  国家自然科学基金项目( 41672241) ; 中国地质调查项目( DD20179375)
