岷江上游生态环境现状与可持续发展对策

Current Situation of Eco-environment in Upper Reaches of Minjiang River and Strategies of Sustainable Development

岷江上游是成都平原的生态屏障和水源生命线。但几十年来,该地区植被的大量砍伐和土地的不合理利用引起了一系列生态恶化问题。在概述岷江上游生态环境现状的基础上,分析了其形成原因:地貌不稳定性、人口过度增长、土地资源的不合理利用。最后提出了实施有计划地退耕还林还草、综合农业措施改良、控制人口增长和推动剩余劳动力转移、构建自然资源可持续利用的战略体系、加强法制监督等可持续发展对策。

The Upper Reaches of Minjiang River served as ecological barriers and the major water supplying area to the Chengdu Plain. However, a series of ecologically maladjusted problems emerged because of the massive lop and reasonless utilization of vegetation in recent decades. On the basis of analyzing the actuality of the eco - environment in the Upper Reaches of Minjiang River, the factors, such as geology instability, population increase and illogical use of land resources were discussed. Finally, it indicated the countermeasures, such as returning cultivated land in steep hill to forest, improving multiple measure for agriculture controlling the population explosion, building resources sustainable strategic system, strengthening the legal supervision.
