江西省2007-2011年水资源生态足迹和生态承载力动态特征

目的]为定量评价江西省水资源可持续发展状态。方法]以水资源生态足迹的基本原理和计算模型为基础,分析了江西省2007—2011年水资源生态足迹、生态承载力和水资源负载指数的动态变化。结果]2007—2011年江西省水资源生态承载力整体上呈现增加的趋势,从2007年的2.029 12×108 hm2增加到2010年的4.151 51×108 hm2。总水资源生态足迹5a整体上呈现增加的趋势,从2007年的3.882 09×107 hm2增加到2011年的4.344 7×107 hm2。万元GDP生态足迹呈逐渐增加的势,水资源利用率有所降低。结论]水资源生态足迹的变化与社会经济发展密切相关。应该充分调整产业结构,合理调度、利用水资源,促进江西省整个社会经济的持续发展。

Dynamic Characteristics of Ecological Footprint and Ecological Carrying Capacity of Water Resources in Jiangxi Province During 2007-2011

Objective] To evaluate the sustainable development condition of water resources in Jiangxi Province.Methods] Based on the principle and calculation model of water resources ecological footprint, the ecological footprint and ecological carrying capacity of water resources in the years from 2007 to 2011 were analyzed.Results] The total water resources capacity gradually increased from 2.029 12×10⁸ hm² in 2007 to 4.151 51×10⁸ hm² in 2010. The total ecological footprint of water resources increased in the past five years, and it increased from 3.882 09×10⁷ hm² in 2007 to 4.344 7×10⁷ hm² in 2011, and the water resources ecological footprint of per ten thousand yuan GDP in Jiangxi Province continued to increase. This indicated that the utilization of water resources in Jiangxi Province gradually decreased in the past five years.Conclusion] The changes of ecological footprint of water resources are closely related to socio-economic development. People should adjust the industrial structure fully, manage and use of water resources rationally, to promote the sustainable development of the overall socio-economy of Jiangxi Province.
