基于EF模型的清水江流域生态环境可持续发展评价

Evaluation on the Development Status of Ecological System in Qingshui River Basin Based on EEF Model

在提取贵州省清水江流域2010—2014年生态环境与社会经济统计数据的基础上,运用生态足迹模型,对其生态足迹、生态承载力、万元GDP生态足迹进行测算与分析,并对清水江流域生态环境可持续能力进行评判。结果显示:2010—2014年清水江流域生态足迹值分别为1.546(hm^2/人)、1.848(hm^2/人)、1.707(hm^2/人)、1.973(hm^2/人)、1.955(hm^2/人),呈现上升趋势;生态承载力值分别为1.228(hm^2/人)、1.223(hm^2/人)、1.214(hm^2/人)、1.205(hm^2/人)、1.196(hm^2/人),总体上呈现下降趋势;生态赤字出现,且呈现上升趋势。反映出研究区生态环境处于弱持续发展状态,生态环境系统开发利用空间较小,承载能力明显不足,此对区域可持续发展潜力有重要胁迫作用。

Based on the data of ecological environment and social economic statistics of 2010-2014 in the Qingshui River Basin of Guizhou province,ecological footprint model is used to calculate and analyze the values of ecological footprint,ecological carrying capacity,ecological footprint of ten thousand yuan GDP,and determine the sustainable development ability of ecological environment in the Qingshui River Basin.The result shows that ecological footprint values of Qingshui River Basin from 2010 to 2014individually are 1.546（hm^2/person）,1.848（hm^2/person）,1.707（hm^2/person）,1.973（hm^2/person）,1.955（hm^2/person）,showing upward trend;Ecological carrying capacity values are 1.228（hm^2/person）,1.223（hm^2/person）,1.214（hm^2/person）,1.205（hm^2/person）,1.196（hm^2/person）,showing ageneral downward trend;the ecological deficit appears in an upward trend.It reflects that the ecological environment in the study area is in a weak state of sustainable development,the development and utilization of the ecological environment system is limited,and the bearing capacity is obviously insufficient.This will have a serious impact on the regional sustainable development of this area.
