摘要:
基于三峡库区1996年,2000年和2005年三峡库区各县市的林地面积,结合GIS分析了三峡库区林地变化的过程及其对林地功能生态价值的影响.结果表明:1996-2000年,林地的面积在减少,随着退耕还林和农业结构调整地实施,2000-2005年,林地面积增加了18502.93 hm2.由于1996-2005年有林地面积有所增加,使得三峡库区有林地生态功能的总价值增加了6.17亿元,大部分县市有林地生态功能总价值在增加,少许几个在减少.针对林地变化、驱动与生态价值研究的结果,对库区退耕还林及农业产业结构调整提出了相关参考意见.
Abstract:
This paper uses the land use data from the land resources survey in 1996,2000 and 2005,chooses the forestry areas and distribution of different counties in Three Gorges reservoir as the research objects,and analyzes the process of forestry change and the change of ecological value which is influenced by the change of forestry based on the GIS.The research results indicate that the area of forestry decreased in 1996--2000,but it increases by 185 024.93 hm~2 in 2000-2005 because of carrying out the policy of returning forestry and the adjustment of agricultural industry structure.The gross ecological value increases by 617 million yuan because of forestry increasing in 1996-2005,ecological values increase in majority counties and decrease in minority counties.At last,some advices are given for the policy of returning forestry and the adjustment of agricultural industry structure and for the land successive use and ecological environment protection.
