基于生态足迹法的延边州水资源生态环境研究

Research on water resources ecological environment of Yanbian Prefecture based on ecological footprint method

根据水资源生态足迹原理及相关模型,对2000-2016年延边州水资源生态足迹、生态承载力、生态盈余和水资源利用效率、负载指数、压力指数、泰尔指数和相关性进行了系统分析.结果表明:延边州各市(县)水资源生态足迹呈波动上升趋势;水资源生态承载力与生态盈余县域间时空差异明显;各市(县)水资源利用效率总体提升但程度不一;延吉市、图们市、龙井市水资源负载与生态压力及泰尔指数均高于其他市(县);影响延边州水资源生态足迹和生态承载力的主要影响因子分别为农业用水(0.986**)和天然降水(0.904**).

According to the principle of water resources ecological footprint and related models,the water resources ecological footprint,ecological carrying capacity,ecological surplus and water use efficiency, load index, pressure index, Thail index and correlation degree of Yanbian Prefecture from 2000 to 2016 were carried out. The results show that the water resources ecological footprint of each city (county) in Yanbian Prefecture is fluctuating upward trend;the spatial and spatial differences between water resources ecological carrying capacity and ecological surplus county are obvious;the water use efficiency of each city (county) is generally improved but the degree is different;Yanji City,the water resources load,ecological pressure and the Thail index of Tumen City and Longjing City are higher than other cities (counties);the main influencing factors affecting the ecological footprint and ecological carrying capacity of Yanbian Prefecture are agricultural water (0. 986**) and natural precipitation (0. 904**).
