Abstract:

By taking Nanchong city, Sichuan province, as research area and studying the historical data from 2007 to 2013, we analyze changes of water resource pressure in Nanchong from four aspects: population pressure, economic development pressure, ecological pressure, and technology pressure.The results are given as follows.1) The economic development pressure of water resources sustainingly decreased from 2007 to 2013.Theoretically, there was no water ecological pressure.The integrated water resource pressure showed a dwindling trend in fluctuation.2) In 2007 and 2012, the integrated water resource pressure of Nanchong mainly concentrated in Shunqing district, Jialing district, and Peng'an county, while the level of pressure rose from medium to super high in Gaoping district.The study on spatial and temporal evolution of water resource pressure in Nanchong is helpful for similar hillock areas to adjust the regional water resource development and utilization planning.

Key words: water resource pressure, index of pressure, spatial and temporal change, hilly region, Nanchong city
