宁夏自治区永宁县2006年生态足迹分析

对地处黄河上游的宁夏回族自治区永宁县生态足迹帐户计算表明,2006年永宁县的人均生态足迹为3.830 hm2,人均生态承载力为3.376 hm2,人均生态赤字0.454 hm2,资源的消耗已明显超出自然再生能力,处于不可持续的发展状态。永宁县生态足迹主要来自于耕地、草地、化石能源消耗,畜牧业比重增加和化石能源消耗增加是永宁县生态足迹增加的主要原因。改善该区生态足迹状况的有效途径。主要有提高化石能源使用率,充分利用可再生能源,种植饲草,压缩养殖规模等。

Ecological Footprints of Yongning County in Ningxia Hui Autonomous Region in 2006

Based on calculation,the ecological footprint,carrying capacity,ecological deficit of Yongning County in Ningxia Hui Autonomous Region is 3.830,3.376 and 0.454 hm2 per capita in 2006,respectively.The results reveal that the rate of resource consumption apparently exceeded that of resource renewal,imply-ing an unsustainable status.The ecological footprints of the Yongning County were contributed mainly by cultivated land,grassland and fossil fuel consumption.The climbing of animal husbandry and fossil energy consumption was the main reasons leading to increases of ecological footprints.The study also pointed out several effective measures to reduce the ecological deficit,and enhance ecological capacity of the Yongning County,such as improving utilization ratio of fossil energy,decreasing industrial energy consumption,deve-loping circular economy,utilizing renewable energy including solar and wind energy,planting forage,and compressing farm sizes.
