安徽省退耕还林驱动力机制分析

The Driving Mechanism for the Conversion of Farmland to Forests in Anhui Province

退耕还林是为了保护生态环境,通过政策和管理措施恢复重建地表结构,建立生态安全条件下的土地利用和土地覆盖格局。自2002年以来,安徽省有17市84个县不同程度地参与到退耕还林生态工程建设中。推动全省退耕还林建设的驱动力主要体现在政策驱动、自然驱动、经济驱动、科技驱动和文化驱动等5个方面。其中,从淮北平原过渡到江淮丘陵直至皖南及皖西山区等5大区域的退耕还林驱动力主要以自然生态驱动和经济驱动因子占主导地位,科技驱动因子是巩固退耕还林生态工程建设的有效手段,文化驱动在具有省域文化特色的区域所占的比重较为突出。

The project of ＂Conversion of Farmland to Forests＂ is carried out with an aim to protect the ecological environment by reconstructing the natural land cover and establishing the land use and land cover pattern under the condition of ecological security. There were 17 cities including 84 counties participating in this project from 2002 to 2009 in Anhui Province. The driving force for the project mainly reflected itself in policy drive, natural drive, economic driver, science and technology driver, and cultural driver at national, provincial or county scales. The natural drive and economic drive played a leading role in five regions across Anhui Province, the science and technology drive was the effective means to strengthen the conversion, and the cultural drive played a relatively more important role in areas with provincial cultural features.
