云南省水资源生态足迹与生态承载力时空动态分析

Analysis of Water Resources Ecological Footprint and Ecological Carrying Capacity in Yunnan Province

应用水资源生态足迹计算模型对云南省近十年及各州(市)近五年水资源生态足迹和生态承载力进行了分析,结果表明:(1)云南省近十年水资源生态足迹变化不明显,而各年份之间的水资源生态承载力差异较大,2001年最高为285×106hm2,2009年最低为175×106hm2。(2)云南省水资源生态足迹较大的区域主要分布于滇中的昆明市和大理市、滇东的曲靖市以及滇东南的红河州,水资源生态足迹均大于2.00×106hm2,而较小的主要分布于滇西北的迪庆州、丽江市和怒江州,均小于1.00×106hm2。

This paper use the calculation model of water resources ecological footprint analyzing the water re- sources ecological footprint and ecological carrying capacity in the past ten years in Yunnan Province and the past five years in all city. The result shows： （1） The water resources ecological footprint in the past ten years is change not obvious in Yunnan province, but the water ecological carrying capacity change is obvious, the water resources ecological carrying capacity in 2001 is the highest for 285×106hm2, 2009 is the lowest for 175×106hm2. （3） The water resources ecological footprint larger area in Yunnan province mainly distribute in Kun- ming.Dali.Qujing and Honghe, all the water resources ecological footprint are more than 2.00×106hm2, and smaller mainly distribute in Diqing.Lijiang and Nujiang, all are less than 1.00×106hm2.
