Utilization and matching patterns of water and land resources in China

The degree of utilization of water and land resources and their matching patterns not only determine the scale of economic development,but also affect regional ecological security.In order to objectively evaluate the spatial matching of the water and land resources in China, data from 346 municipal districts were used in this study to analyze the development conditions of water and land resources in China in 2005,2010 and 2015,respectively,and the Gini coefficient was also used to explore the matching characteristics of water and land resources in different provinces. It was found that the North China Plain,the Hexi Corridor and the western part of the Tarim Basin were the regions having the highest development degree of water resources in China.The Northeast Plain,the North China Plain,the Guanzhong Plain,the Sichuan Basin and the coastal areas of Guangdong were the regions having the highest development degree of land resources. In addition,Gansu,Shaanxi,Inner Mongolia and Tibet were the provinces with the widest gap between water and land resources,among which Gansu,Shaanxi and Inner Mongolia had the widest gap because the water resources could not support the local land resources,while Tibet was due to the land resources being unable to match rich water resources.
