基于PSR模型的四川省升钟水库生态安全评价

Ecological Security Evaluation Based on PSR Model for Shengzhong Reservoir in Sichuan Province

摘要:通过PSR(Pressure-State-Response)模型建立水库生态安全评价的指标体系,用熵权法确定17个指标的权重,运用Excel软件对数据进行处理,评价了四川省升钟水库的生态安全情况.结果表明,2004-2007年升钟水库生态安全状况呈逐年好转趋势.讨论了水库生态环境保护的多项措施,包括取缔网箱肥水养殖,加强库区居民点生活垃圾与污水处理,治理库区水土流失,减少面源与点源污染物氮、磷入库量,严防水葫芦泛滥,注重治理水体富营养,使水库的蓄水量保持在合理水平等.同时,应注意水库垂钓等新因素对升钟水库生态平衡的影响.
