果洛州2002年生态足迹与发展能力分析

在介绍生态足迹概念及计算方法的基础上,以江河源区果洛州6县2002年统计年鉴的数据为依 据,对果洛州2002年的生产性生态足迹、生态承载力、生态足迹多样性指数、发展能力和GDP生态足迹进行了计 算。结果表明,果洛州2002年的生态足迹为465 405．112 hm2,实际可供的生态承载力为545 353．338 hm2,人均生 态足迹盈余为0．591 hm2,其中果洛州的甘德县和玛多县为生态足迹赤字,班玛县、久治县、玛沁县和达日县为生态 足迹盈余,说明在当前生产技术水平下,果洛州处于较弱的可持续发展状态。果洛州2002年生态足迹多样性指数 和发展能力低,而GDP生态足迹较高,反映该区域生态系统结构单一,稳定性差,资源利用效率低。

Analysis of ecological footprint and development capacity of Guoluo prefecture in 2002

With the introduction of ecological footprint concept and the statistical data of 6 counties in Guoluo in 2002 as the basis, the productive ecological footpring, ecological carrying capacity, ecological footprint diversity,development potential and GDP ecological footprint of Guoluo region in 2002 were calculated. The result shows that the ecological footprint is 465 405. 112 hm^2,and the ecological capacity in only 545 353. 338 hm^2,with a ecological surplus of 0. 591 hm^2 per capita,but only two of six counties is ecological deficit ,so it shows that Guoluo prefecture is weak in sustainable development. The ecological footprint diversity and development capacity is lower and GDP ecological footprint is higher,which reflect the ecosystem stability and resource utilization efficiency are lower.
