1996—2005年临沂市生态足迹动态研究

Study on the dynamics of ecological footprint in Linyi city during 1996—2005

基于生态足迹模型测算了临沂市1996—2005年的生态足迹和1996年、2000年、2005年的生态承载力,分析了临沂市的可持续发展程度.结果表明:1996—2005年临沂市人均生态足迹需求增加0.598 34 hm2,人均生态足迹化石能源分量2005年与1996年相比增加4倍多,其他5类分量的动态变化波动较大.1996—2005年生态承载力下降,由生态盈余变为生态赤字,生态足迹压力指数由1996年的0.310 94增加到2005年的1.518 68,万元GDP生态足迹显示临沂市资源利用率较低.人均生态足迹趋势线显示临沂市2006—2010年生态足迹将继续增加,生态赤字和生态足迹压力指数将继续呈现上升趋势.

Based on the ecological footprint model, the ecological footprint during 1996--2005 and the ecological capacity in the year of 1996, 2000 and 2005 in Linyi city were calculated, and the degree of sustainable development in Linyi city was also analyzed. The results showed that the ecological footprint per capita increased by 0. 598 34 hm^2 from 1996 to 2005 in Linyi city; the need of fossil resource per capita ecological footprint in 2005 was more than 4 times than that in 1996, and the other five factors fluctuated greatly. The ecological capacity declined from 1996 to 2005, and it changed from the ecological profit to the ecological deficit. The pressure index of ecological footprint increased from 0. 310 94 in the year of 1996 to 1. 518 68 in the year of 2005. The ecological footprint per 10 thousands GI3P illustrated that resource use efficiency in Linyi city was relatively low. According to the trend line of the per capita ecological footprint, the ecological footprint of Linyi city will increase in the year of 2006--2010, and so do the ecological deficit and pressure index of ecological footprint.
