基于生态足迹供给模型的生态承载力评价

生态足迹供给模型是定量计算地区生态承载力的有效工具。对黑龙江省鹤岗市、内蒙古自治区奈曼旗以及四川省泸州市规划实施前后的人均生态足迹供给量进行了计算，结果显示，鹤岗市与奈曼旗生态足迹供给水平较高，人均生态足迹供给在2．5ha左右，均高于1．5ha的国内生态足迹和2．2ha的全球生态足迹平均水平。泸州市生态足迹供给约为0．508ha，区域可持续发展程度属弱可持续。但由于不同地区的同种土地利用类型存在较大差异，还需要针对各地具体情况开展基础研究工作，才能使生态足迹供给模型更有效、更科学地利用到生态承载能力评价当中。

Evaluation of Ecological Carrying Capacity Based on Ecological Footprint Supply Model

Ecological footprint supply model provides an effective method to quantitatively calculate regional ecological carrying capacity.The supplies of per capita ecological footprint of Hegang of Heilongjiang province,Naiman country of Inner Mongolia and Luzhou of Sichuan province before and after the plan are calculated respectively.The result shows that the supply of Hegang and Naiman which is about 2.5 ha is higher than 1.5 ha of the domestic and 2.2 ha of the world,and the supply of Luzhou is 0.508 ha which m...
