摘要:

为评估并分析延边州的水资源生态足迹和生态承载力，基于生态足迹分析方法，对延边州2006-2015年水资源生态足迹、生态承载力、生态盈余、万元GDP水资源生态足迹以及延边州各县市的水资源生态足迹与生态承载力的空间分布进行了分析和水资源基础数据的计算。结果表明，在2006-2015年间延边州水资源生态足迹总体呈波动上升趋势，用水主要以农业用水为主，分析年份延边州平均农业用水、工业用水、生活用水、生态用水足迹分别为99.77×10⁴、19.95×10⁴、18.36×10⁴和2.07×10⁴ hm²，占水资源总生态足迹的71.2%、14.2%、13.1%、1.5%；水资源生态承载力与生态盈余的变化趋势类似，波动显著；10年间延边州水资源消耗量减少，水资源利用效率逐渐提高；延边州8个县（市）水资源生态足迹与生态承载力空间分布不均衡，存在一定的地区差异。

Abstract:

Based on the analysis method of ecological footprint,the water resources ecological footprint,ecological carrying capacity,ecological surplus,and water resources ecological footprint per 10 000 yuan GDP and spatial distribution on water resources ecological footprint and load-carrying capacity of each region in Yanbian area from 2006 to 2015 were analyzed.The results showed that,the water resources ecological footprint displayed a fluctuating upward trend in Yanbian area from 2006 to 2015,agricultural water was dominated,the agricultural water,industrial water,domestic water,ecological water footprint was 99.77×10⁴,19.95×10⁴,18.36×10⁴ and 2.07×10⁴ hm²,respectively,took up 71.2%,14.2%,13.1%,1.5% of the total water resources ecological footprint;The changing trend of water resources ecological carrying capacity and ecological surplus were similar,and the fluctuation was significant;The water consumption showed a decreasing trend from 2006 to 2015,indicating the increasing of utilization of water resources;The spatial distributions of water resources ecological footprint and ecological carrying capacity of 8 counties (cities) in Yanbian area were not balanced,and there were some regional differences.
