中文摘要研究汶川地震灾区生态脆弱性等级差异与空间格局特征,对合理规划土地资源和生态环境保护具有指导作用。选取资源成因、环境成因和社会经济3大体系的16个指标构建了生态脆弱性评价指标体系。利用DARE法和生态脆弱度对其评价指标进行加权分析计算,建立了4个等级生态脆弱性。结果表明,龙门山断裂带中心带及秦巴山地生态脆弱性最强,西部高原区域的生态脆弱性较强,山前平原地区为中度,东部丘陵地区生态脆弱性次之,并分析了土地利用规划现状和地震次生灾害分布对生态环境影响,证明了评价结果符合汶川地震灾区的生态环境状况。
英文摘要The Wenchuan earthquake area is one of the typical vulnerable areas in our country.Its vulnerability is quite evident on account of the seismically triggered geo-hazards like debris flow and landslide,variable geography remarkably different in height and wet climate,and human activities.In the light of the analysis which involves the factors,16 indexes including productivity of water,land use ratio,farmland area per person,topography and geomorphology,geological hazard degree,social economic development level,etc.are selected in order to set up an assessment index system.The system consists of four grades by DARE(decision alternative ratio evaluation)method and weighted ecological frangibility degree in evaluation index.Results show that ecological vulnerability is the strongest in the core of Longmen Mountains fault zone and Qinba Mountains,the stronger in the western plateau,moderate in piedmont plain,and the weakest in east hilly region.The influences of the landuse status and the distribution of earthquake induced disasters on ecological environment are analyzed.Result from the evaluation is important to guide economica1 development and ecological environment construction in the Wenchuan earthquake area.
