The Baiyang River Basin in Xinjiang is a region with combined drought and extreme aridity,where water scarcity has resulted in a significant trade-off between ecological water use and water allocation for industrial and domestic purposes.In order to scientifically and effectively utilize water resources,provide theoretical basis for water resource planning and optimal allocation of the river ecosystem in the Baiyang River Basin and promote coordinated development of economy,society and ecology of the watershed,the ecological water requirement of rivers in the Baiyang River Basin and of vegetation,wetland and urban ecology are calculated by Tennant method and area quota method based on hydrometeorological data and remote sensing data,and studies the ecological water demand inside and outside the Baiyang River Basin in Xinjiang.Results showed that the minimum ecological water requirement for maintaining ecological stability of the Baiyang River Basin is 151.243 2 million m3,including 59.644 5 million m3 for river ecological water requirement,49.632 million m3 for vegetation ecological water requirement,7.496 7 million m3 for wetland ecological water requirement,and 34.47 million m3 for urban ecological water requirement.The river ecological water requirement in the Baiyang River Basin is mainly concentrated from June to September,while the vegetation ecological water requirement is mainly concentrated in July and August.Additionally,ensuring the ecological water requirement in the downstream areas of the basin is crucial.
