基于生态足迹的德州市土地承载力评价

将生态足迹方法应用于德州市土地承载力评价,结果表明:2002~2006年,德州市人均生态承载力由0.493 7 hm2增长为0.560 2 hm2,年均增长2.69%;人均生态赤字由1.174 hm2增加到3.067 hm2,年均增长32.25%,人类活动对自然生态系统的影响已经超出了当地生态承载力的限度,人地关系趋于紧张。最后对生态足迹应用与土地承载力评价进行了讨论。

Ecological Carrying Capacity Evaluation of Dezhou City Based on Ecological Footprint

The ecological footprint method is used to evaluate land carry capacity of Dezhou city.The results show that from 2002 to 2006,the ecological carrying capacity per capital of Dezhou city increased from 0.4937 hm2 to 0.560 2 hm2,the annual increase rate is 2.69%,the ecological deficit per capital increased from 1.174 to 3.067,the annual increase rate is 32.25%.The influence of human activities on natural ecosystem has exceed the limit of local ecological capacity.The relation between human and nature has become more and more tense.In the end,the application of ecological footprint method in the land carry capacity evaluation is discussed in this paper.
