摘要
水资源可持续利用能力评价是世界普遍关注的热点问题。本文以新疆玛纳斯河流域为例,构建了水资源可持续利用评价指标体系,该体系由水资源系统、社会系统、经济系统和生态环境系统4个子系统13项指标组成,将水资源可持续利用水平划分为高中低3类。采用突变级数法与改进障碍因子诊断模型对研究区不同时期水资源可持续利用水平进行评价,结果表明:不同时期(2000年、2010年与2020年),研究区水资源可持续利用水平均处于中等水平(综合值为0.689),为Ⅱ级,但其综合值由2000年的0.689提升至2020年的0.829;水资源开发利用率过高、单位面积水资源量不足与林草覆盖率较低,已成为制约研究区水资源可持续利用的普遍问题。研究结果为区域水资源优化配置提供了重要参考。
Evaluation of sustainable utilization ability of water resources is a hot topic focused all over the world. In the paper, Xinjiang Manas River basin is adopted as an example to construct sustainable utilization evaluation index system of water resources. The system is composed of 13 indicators of 4 subsystems, namely water resources system, social system, economic system and ecological environment system. Sustainable utilization level of water resources is divided into three levels, namely high level, medium level and low level. Mutated series model and improved obstacle factor diagnosis model are adopted for evaluating sustainable utilization level of water resources during different periods. The results show that the sustainable utilization level of water resources in the study area is in the medium level （ comprehensive value is 0. 689 ） , namely grade II. However, the comprehensive value was increased from 0. 689 in 2000 to 0. 829 in 2020. High development and utilization rate of water resource, insufficient water resource quantity per unit area and low forest coverage have become common problems restricting sustainable utilization of water resources in the study area. The research results provide important reference for the optimal allocation of water resources in the region.
