摘要
选择四川北部典型丘陵区——南充市为研究区,基于2007—2013年历史数据,从水资源的人口压力、经济发展压力、生态压力和技术压力4个角度分析探讨南充市水资源压力变化.结果表明:2007—2013年,南充市水资源的经济发展压力持续减小,理论上不存在水资源生态压力,而人口压力和技术压力相对稳定,水资源综合压力在波动中呈缓慢下降趋势.在空间分布上,2007年和2012年,南充市水资源综合压力主要集中在顺庆区、嘉陵区和蓬安县,高坪区水资源压力状况由中等变为巨大.
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 and2012,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.
