基于生态足迹模型的新乡市耕地可持续利用研究

Sustainable use of arable land in Xinxiang City based on the ecological footprint model

运用生态足迹模型对新乡市2004年～2009年耕地的生态足迹进行了分析.结果表明,在研究时段内新乡市人均耕地足迹和生态承载力均呈逐年增长趋势,其中2005年～2006年增长幅度较大.六年间新乡市耕地生产力可持续指数呈波动下降状态,总体上维持在0.535左右,说明新乡市2004年～2009年的耕地利用处于弱可持续发展阶段.

The ecological footprint model was used to analyse the ecological footprint of arable land in Xinxiang City from 2004 to 2009. The result indicates that the per capita arable land footprint and ecological carrying capacity of Xinxiang City show an increasing tendency during the study period, among which the fastest is from 2005 to 2006. During the six years, the productivity sustainability index of arable land of Xinxiang city declines in volatility, maintaining at about 0. 535, which means that it was a weak sustainable level of arable land use from 2004 to 2009 in Xinxiang City.
