1990-2004年安徽省生态足迹动态分析

文章采用可变世界单产法计算了1990—2004年安徽省域尺度上的生态足迹,表明研究期内人均生态足迹和人均生态赤字分别由1990年的1.0121 hm2、0.5014 hm2增加到2004年的1.6523 hm2和1.2397 hm2,人均生态承载力和万元GDP生态需求则分别由0.5108 hm2、8.5601 hm2减少到0.4125 hm2和2.1270 hm2。说明了近年来安徽省人口对自然资源的消费量逐年增加,超出自然生态系统的承载能力,生态足迹与生态承载力之间的矛盾加剧,社会经济的发展模式不可持续。

Dynamic analysis of the EF of Anhui Province from 1990 to 2004

The ecological footprint(EF) of Anhui Province during the period from 1990 to 2004 is calculated with the method of variable world average yield.The results are as follows:the average personal ecological footprint gradually increased from 1.012 1 hm2 to 1.652 3 hm2 during 1990 to 2004;the average personal ecological deficit increased from 0.501 4 hm2 to 1.239 7 hm2;the average personal ecological capacity declined year by year from 0.510 8 hm2 to 0.412 5 hm2;and the average personal ecological footprint per ten thousand yuan GDP dropped from 8.560 1 hm2 to 2.127 0 hm2.The research indicates that the utilization of natural resources in Anhui Province is increasing year by year and has been beyond the capacity of the natural ecological system,so the conflicts between the ecological footprint and ecological capacity are aggravated,and the ecological environment is at risk.Some suggestions for sustainable economic development are given.
