基于耕地生态足迹的重庆市耕地生态压力变化研究
以耕地生态压力为切入点,应用耕地生态足迹模型,在修正了Wackernagel提出的耕地产量因子的基础上,构建耕地生态压力指数,并借用IPAT分析,以2000、2010年为起止点,对重庆市的耕地生态压力变化状况进行了系统研究.结果表明:(1)2000-2010年间,重庆市的耕地生态压力有所好转,耕地生态压力指数在10年间减少了0.0623,耕地生态压力一直处于平衡偏高状态;(2)耕地生态压力状况与区域经济发展程度、人口数量呈正相关关系,1小时经济圈耕地生态压力最重、渝东北次之、渝东南最次;(3)2000-2010年间重庆市的生产技术大量提高,单位经济产值所带来的耕地生态环境的冲击力逐年减小.该研...

| Summary: | 以耕地生态压力为切入点,应用耕地生态足迹模型,在修正了Wackernagel提出的耕地产量因子的基础上,构建耕地生态压力指数,并借用IPAT分析,以2000、2010年为起止点,对重庆市的耕地生态压力变化状况进行了系统研究.结果表明:(1)2000-2010年间,重庆市的耕地生态压力有所好转,耕地生态压力指数在10年间减少了0.0623,耕地生态压力一直处于平衡偏高状态;(2)耕地生态压力状况与区域经济发展程度、人口数量呈正相关关系,1小时经济圈耕地生态压力最重、渝东北次之、渝东南最次;(3)2000-2010年间重庆市的生产技术大量提高,单位经济产值所带来的耕地生态环境的冲击力逐年减小.该研究可为重庆市的耕地生态安全预警、土地整治以及区域可持续发展提供理论依据. |

| Bibliography: | 44-1267/S The study constructs the exponent of cultivated land ecological pressure., uses the relation of the cultivated land ecological pressure as Pointcut, apply the model of "cultivated land Ecological Footprints Method" , consider the factors of cultivated land production revised by Wackernagel, and use IPAT analysis, take the data of the of 2000 and 2010 as an enthesis and making a systematic research in the variation of cultivated land ecological pressure of Chongqing. The results indicated that: (1) Between 2000 and 2010, cultivated land ecological pressure had ameliorated, and exponent of cultivated land ecological pressure had decreased 0.0623. However, cultivated land ecological pressure had been in medium high.(2)Standard of cultivated land ecological pressure positively correlated regional economic development and population. Cultivated land ecological pressure Northeast Chongqing is smaller than one-hour economic circle, and cultivated land ecological pressure southeast economic Chongqing is mini |
