| 摘 要： | 随着塔里木河流域水资源统一管理不断加强,塔里木河下游生态输水量增加,生态保护取得了阶段性成效.然而,水资源严格管理下的塔里木河下游水生态安全状况及变化过程如何,相关研究缺乏科学的评估.对此,本文利用塔里木河下游2000—2017年的水量、监测断面地下水埋深、胡杨新增生物量、植被覆盖度、干旱指数等指标数据,运用主成分分析...

| Abstract: | Due to the continuous strengthening of the unified water resource management programs in the Tarim River Basin,the ecological water transport in its lower reaches has increased,and periodic improvements in ecological protection have been achieved.However,there is a lack of scientific evaluation regarding the impact of strict water resource management program on the water ecological security status and changes.This study used principal component analysis and comprehensive coefficient method to evaluate the water ecological security status and reveal the changing characteristics of the driving factors affecting it.The analyses were based on the 2000 to 2017 index data of water quantity,groundwater depth of the monitored section,new Populus euphratica biomass,vegetation coverage,and drought indices in the lower reaches of the Tarim River.The results showed that from 2000 to 2017 the comprehensive water ecological security evaluation index increased from 39.1 to 84.7,and the ecological security level continuously improved,changing the area from a“moderate warning”to a“safe”area.Hydrological and vegetative influences are the two driving factors affecting downstream water ecological security;therefore,the volume of discharge,groundwater depth,and vegetation diversity significantly impact water ecological security.This study could provide an important scientific basis for optimizing the ecological water transport model in the lower reaches of the Tarim River. |
