Water regulation has been carried out by the Heihe River Bureau since 2000,which aims to address the existing eco-environmental problems in the lower Heihe River.In the past nine years,great changes in spatial-temporal distribution of water resources took place in the lower Heihe River.In order to objectively evaluate the influence of water regulation on the eco-environment,the changes of groundwater table,typical vegetation,landscape types as well as East Juyan Lake have been analyzed in the lower Heihe River,by means of field surveys and remote sensing.These results indicate that there are obvious effects of water regulation on the eco-environment,which has been improved toward sustainability in the lower Heihe River.
