Abstract:

Based on the improved analytic hierarchy process, the authors adopted a 3-scale (0, 1, 2) matrix method to establish regional water ecological security assessment system including 3 layers and 24 indicators according to the real conditions of water environment in Xingtai City. The ecological security assessment system could analyze the influence factors of water environmental security status and evaluate the security situation in Xingtai City. The results showed that the five top influence factors were sewage treatment rate, annual precipitation, wastewater total amount, industrial waste water discharged and urban residential domestic sewage in the 24 indicators. The composite evaluating indexes of the water environment ecological security were within the bandwidth of 0.36 to 0.63, which indicated that the water environment ecological security was still in severe with general or poor state. Some coping strategies and suggestions were put forward to water environmental safety in Xingtai City. The research would provide a theoretical basis for water resource sustainable utilization and a reference for the similar natural condition areas.

摘要:

通过对传统层次分析法的改进, 采用构建三标度(0, 1, 2)矩阵的方法, 构建3个层次、24个指标的水环境生态安全评价体系, 对邢台市水环境生态安全影响因素进行分析和判别, 对水环境生态安全状况进行评价。结果显示, 在24个评价指标中, 污水处理率、年降水量、废水排放总量、工业废水排放量和城镇居民生活污水排放量列权重在前5位; 2006—2015年邢台市水环境生态安全综合评价指数在0.36~0.63之间, 水环境生态安全处于一般状态和较差状态, 安全形势严峻。对邢台市水环境生态安全问题提出相应的对策和建议, 为水资源可持续利用提供理论依据, 同时为具有类似自然条件的地区的生态安全评价提供借鉴。
