滁州市耕地承载定量分析

基于2000—2010年滁州市TM数据,结合研究区耕地生物资源数据,运用生态足迹方法,对滁州市耕地承载进行定量分析。结果表明:2000—2010年滁州市人均耕地减少16.4%,人均耕地面积明显低于联合国粮农组织规定的人均耕地警戒线;2010年滁州市人均耕地生态承载力远低于全球水平,人均耕地生态承载力减少与人口数量增长呈负相关关系;2000—2010年滁州市耕地生态承载等级从富富有余转变为超载与平衡临界状态,琅琊区耕地生态承载等级由富富有余转化为过载,南谯区耕地生态超载等级变化较小。划定基本农田范围,严守耕地保护红线,发展现代农业,提高耕地整体性和机械化水平,是缓解滁州市耕地生态超载的基本措施。

Quantitative Analysis of Cultivated Land Carrying Capacity in Chuzhou City

Based on TM data in Chuzhou during 2000-2010, combined with data of biological resources of cultivated land in the study area , adopting ecological footprint method, the cultivated land carring capacity in Chuzhou City were quantitatively analyzed.The results showed that:2000-2010, the per capita cultivated land in Chuzhou decrease of 16.4%, significantly lower than the per capita cultivated land cordon FAO regulations.Per capita ecological carrying capacity of cultivate land in Chuzhou City in 2010 far below the level of the world.Per capita ecological carring capacity of cultivated land reduce and population growth was a negative correlation.2000 -2010, the ecological carrying level of cultivated land in Chuzhou transfered from more than enough to overload and balanced critical state;ecological carrying level of culti-vated land in Langya District transfered from more than enough to overload; ecological overload level of cultivated land in Nangiao District changed smaller.Delimiting the scope of basic farmland,protecting the red line of cultivated land strictly,developing modern agriculture, and improving the overall level of mechanization of cultivated land, were the basic principles of alleviate ecological overload of culti vated land in Chuzhou City.
