摘　　要：开展胡杨林生态补水对于保护和修复干旱区自然生态系统,实现流域高质量发展具有重要意义。该文基于生态输水后植被调查和遥感监测等基础数据,客观评估了叶尔羌河生态输水效益,结果表明:生态输水影响面积10.28万hm2,其中适度淹灌(8-28 d)区域2.50万hm2;地下水储量以增加趋势为主,其中增长50~150 mm的区域占总面积的82.40%;地下水埋深较输水前抬升0.50~2.00 m;物种多样性指数较未输水区高40%~60%左右,遥感生态指数RSEI均值提升8.62%。研究成果对于指导干旱区生态输水的精准化、科学化工作提供了重要指导,也为类似地区生态输水提供了参考。It is of great significance to carry out ecological water replenishment of Populus euphratica forest for protecting and repairing the natural ecosystem in arid areas and achieving high-quality development in the river basin.Based on the basic data of vegetation survey and remote sensing monitoring after ecological water conveyance,this paper objectively evaluated the ecological water conveyance benefits of the Yarkand River.The results showed that the ecological water conveyance affected an area of 10.28×104 hm2,The area of moderate irrigation(8-28 days)was 25,000 hectares.The underground water storage trend increased,and the area with an increase of 50~150 mm accounts for 82.40%of the total area.the buried depth of groundwater is 0.50~2.00 m higher than that before water transmission.The species diversity index is about 40%~60%,higher than that of the non-water conveyance area,and the mean value of the remote sensing ecological index RSEI is 8.62%higher.The research results provide important guidance for the precise and scientific work of ecological water transportation in arid areas,and also provide reference examples for ecological water transportation in similar areas.
