南充市水土流失的人为因素分析及对策研究

Artifical Factors of Soil Erosion and Countereasures of Nanchong City

南充市改革开放实施以来,由旧城改造、土地置换进入城市振兴,作为川东北区域中心城市的现代大都市特征日益明显。但南充市水土流失问题严重,并制约着国民经济的发展。南充市水土流失的人为因素主要来自3方面:为提高农业产值而导致的植被破坏,城区面积的快速扩展和众多基建项目的实施。这些都对水土流失产生了重大影响。对此,笔者提出建议:提高认识,强化水土流失治理的行政举措,恢复植被,更新以本地物种为主的城市绿化观念,恢复和建设湿地水域,保证城市发展的可持续性。

Since reforms and open policies were initiated, Nanchong city has been constructed as a center of northeast Sichuan Province by modifying its old districts and selling its land. However, the caused soil erosion is severe that it restricts Nancbong city＇s developments. Analyzing the human factors resporsible for soil erosion in Nancbong City, the author pointed out the following three reasons-vegetation destruction caused by farming, encroaching farm land for urbanization and setting up many infrastructures. Based on above analyses, some suggestions are given that we should heighten public awareness, and restore vegetation and wetlands. For the sustainable development of the city, the suggestions should be implemented by enhancing administrative management and propagandizing viewpoint that plant more local trees in the city.
