Abstract: Tongzhou District has been put forward as the new developing centre of Beijing City. But the serious water deficiency and pollution restricted the local sustainable development. In this paper, an integrated water resource carrying capacity (IWRCC) model was developed under the sustainable development principle and the “natural- social” water cycle to quantify IWRCC of Tongzhou District. Three scenarios were designed to increase IWRCC and results showed that there was a great gap between IWRCC and the development plan in Tongzhou District. Water shortage restricted urbanization and sustainability seriously and transferring water from other regions besides promoting water saving and controlling pollution in the region would be the most feasible solution for Tongzhou District to mitigate the water shortage stress.

Key words: integrated water resource carrying capacity (IWRCC), ray association analysis, ustainability, ongzhou District
