重庆市水资源生态足迹与生态承载力分析

Analysis of Water Resources Ecological Footprint and Ecological Carrying Capacity in Chongqing City

利用水资源生态足迹分析方法对重庆市2000～2009年的水资源生态足迹、生态承载力进行了分析。重庆市历年水资源承载力大于水资源生态足迹,存在一定的生态盈余,水资源生态承载力受干旱等自然灾害影响较大。重庆市水资源生态足迹在逐年提高,万元国内生产总值水资源生态足迹在逐年下降,水资源开发利用程度和利用效率逐步提高。重点讨论了水资源生态足迹在三次产业间和城乡间的差异。

According to the calculation model of water resources ecological footprint, the water resources ecological footprint and ecological carrying capacity in the years from 2000 to 2009 in Chongqing City were analyzed. The results showed that the water resources carrying capacity were more than the water resources ecological footprint in the nine years in Chongqing, the ecological surplus was existed. On the other hand, water resources ecological carrying capacity was impacted by drought. The water resources ecological footprint of Chongqing increased in the pasted nine years, while the water resources ecological footprint per 104 Yuan GDP continued to decrease. This indicated that the utilization of water resources in Chongqing gradually increased in the pasted years. The differences among the primary industry, secondary industry and tertiary industry, and between urban and rural areas in Chongqing City were discussed.
