黄土高原退耕还林工程对生态环境的影响及对策建议
Impacts and Advice of the Grain for Green Project to Ecological Environment on the Loess Plateau
摘要
Abstract
China has implemented the Grain for Green Project since 1999 for reconstructing a graceful northwest region based on serious water and soil loss as well as deteriorative ecological environment of this area.We analyze the impacts on what climate and vegetation zone moved toward south and the damage of the agriculture and animal husbandry development from climate change of the neolithic age and the human activities before and after the agricultural civilization to ecological environment on the Loess Plateau,and point out vegetation cover,the optimization of land resources and region climate have gained remarkable benefits since implementation of the Grain for Green.Meanwhile,it indicates some problems about the increase in water resources demand,the fall in crop production due to decrease of farmland and policy sustainability,and pro poses adjusting measures to local conditions,selecting the appropriate tree species and utilizing water-saving measures to alleviate water resources problems,further optimizing the distribution of land based on ecological,economic and social maximization,providing the reasonable economic compensation and consolidating the results with respect to follow-up engineering management and maintenance in order to provide some guiding functions to further boost the implementation of the Grain for Green Project.关键词
