【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99.77×10~4、19.95×10~4、18.36×10~4和2.07×10~4 hm~2,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]:In order to evaluate and analyze the ecological footprint and ecological carrying capacity of water resources in Yanbian prefecture, based on the ecological footprint analysis method, the ecological footprint, ecological carrying capacity and ecological surplus of water resources in Yanbian prefecture from 2006 to 2015 were studied. The ecological footprint of water resources and the spatial distribution of ecological footprint and ecological carrying capacity of water resources in the counties and cities of Yanbian state were analyzed and the basic data of water resources were calculated. The results showed that the ecological footprint of water resources in Yanbian Prefecture was fluctuating and rising in the period from 2006 to 2015. The main water use was agricultural water, the average agricultural water use, industrial water use and domestic water use in Yanbian prefecture were analyzed. The ecological water use footprint was 99.77 脳 10 ~ (4) ~ (4), 19.95 脳 10 ~ (4) ~ (4) ~ 18.36 脳 10 ~ (4) h ~ (-2) and 2.07 脳 10 ~ (4) h ~ (-1), respectively, accounting for 71.2 脳 10 ~ (4) ~ (-1) of the total ecological footprint of water resources, and the trend of water resources ecological carrying capacity was similar to that of ecological surplus, and the water resources consumption decreased and water resources utilization efficiency gradually improved in Yanbian Prefecture during the ten years of fluctuation. The spatial distribution of water resources ecological footprint and ecological carrying capacity in 8 counties (cities) of Yanbian Prefecture is not balanced, and there are some regional differences.
