Abstract
Land and water are two of fundamental resources to maintain basic function of urban area. The consumption process of them are twisted together (water production needs equipment to filter raw water, and treat wastewater, agriculture land needs water to grow grain, etc.). Most current nexus studies are focusing on specific project or process. However, unveiling the pathway and destination of land use and water consumption is also important to instruct the development of city area, and to manage and save these two resources synergistically. This study applied environment input output analysis to measure the water and land consumption in a city in China, meanwhile the nexus relationship is also quantified to better understand how these two resources influence each other and further affect the industry supply chain in the city. The results showed that the agriculture is the most crucial economic sector to take land and water synergistical management, especially the production of oil seeds and corn. Besides, the Leasing and Business Services, and Residential Services and Other Services industries, the Food and Tobacco Processing and Water Conservancy, Environment and Public Facilities Management industry are also sensitive industries to implement water and land synergistical management.
