阿克苏河流域土地利用覆被变化及生态需水研究
Study on Land Use/Cover Change and Ecological Water Requirement in the Aksu River Basin
摘要
Abstract
To ensure the rational allocation of water resources and the stability of the ecosystem in the Aksu River Basin,this study sys-tematically analyzed the trends of land use and vegetation cover change in the basin by using multi-source remote sensing satellite data.Combined with the phreatic evaporation model,the ecological water requirement of natural vegetation in the basin was quantified.The re-sults show that from 2000 to 2020,the area of residential-industrial land and cultivated land in the Aksu River Basin increased most sig-nificantly,with growth rates of 120.85%and 51.23%respectively;the area of shrub land and open forest land showed a continuous de-creasing trend,with reduction rates of 20.86%and 20.42%respectively;the changes in the area of water bodies and unused land were relatively insignificant.Based on the forest and grass coverage data of the Aksu River Basin,the basic ecological water requirement of natural vegetation in the basin was calculated to be 214 million m3,among which the total ecological water requirement of the riparian zone from the two rivers to the Xidaqiao coordination section was 32 million m3,and the total ecological water requirement of the Xidaqiao-Barrage section was 182 million m3.The research results are of great significance for formulating effective ecological protection policies and measures and maintaining the balance of the oasis ecosystem.关键词
