辽宁老工业基地改造中的区域可持续发展研究

通过运用国际上流行的生态足迹模型对2001年辽宁省及其14个城市的生态负荷与生态容量进行了详细的计算和结构、布局分析.结果表明辽宁省除锦州外,其他城市的生态负荷均超过了其生态容量,产生生态赤字,全省人均生态赤字为1.31 hm2;生态足迹赤字表明辽宁对生态生产性土地消费需求超过了其生态容量,区域发展模式处于相对不可持续状态.化石能源消费是生态负荷的主要来源,全省该项足迹为1.63 hm2·cap-1,占总足迹的67.3%;上述生态赤字较高的5市的化石能源足迹比例也比较大,均在75%以上.

On the Sustainable Development During Reconstruction of Liaoning Old Industrial Base

Presents in detail the calculate results of the ecological footprints and bio-capacities in Liaoning Province and its 14 cities in the year 2001, as well as an analysis made to its ecological structure/system. A clear outlook is thus provided for the developing sustainability of the province. The results show that the ecological footprints, i.e., human land consumption, of all cities in Liaoning have exceeded their respective bio-capacities except for Jinzhou City, thus causing the high ecological deficit from which the per capita value of the deficit is up to 1.31 hm²·cap^-1. The fact implies that the resource-exhausted development in the region has been in a relatively unsustainable state, especially the consumption of fossil fuels is found to be the root cause of the resource-exhausted ecological footprint which has been up to 1.63 hm²·cap^-1 or 67.3% of the total. In the five cities with higher ecological deficits, i.e., Panjin, Anshan, Benxi, Liaoyang and Fushun, the ecological indicated by fossil fuel consumption are up to over 75% of their respective total. Based on the components and geographical distribution of ecological footprint, a strategic policy is proposed to lead Liaoning to develop in a more sustainable way.
