| 摘 要： | 利用生态足迹方法对珠江三角洲地区9个地市自然资本的供需状况进行了分析,结果表明珠江三角洲地区的整体生态足迹需求为1.5403 hm2/人,三角洲整体及9市人均生态足迹需求高于全国平均水平,对化石燃料的需求占总生态足迹需求的72.67%,位居第一位.珠江三角洲生态足迹供给量最少的地区为佛山、东莞和广州.珠江三角洲地区及9市均存在生态赤字,珠江三角洲人均尚需要生态足迹1.14 hm2/人.具有多种较高生态服务功能的耕地、草地、水域和化石燃料废气(CO2)吸收用地的供给均远远小于需求,包括林地在内的生物生产用地正在以较高的速度流失.受工业化程度的影响,化石燃料的供需状况是影响各地区生态赤字的关键因素.

| Abstract: | The analysis of the supplying and demanding status of natural capital for Zhujiang Delta and its 9 cities was made with ecological footprint method.The results showed that the whole demanding of ecological footprints is 1.5403 hm~2/person and the average demanding of ecological footprints of the whole region and its 9 cities is higher than that of whole country.The requirement on fossilfuel is the top one and takes up 72.67% of ecological demanding.The regions with most poor supply in Zhujiang Delta are Foshan,Dongguan and Guangzhou.The whole delta and its 9 cities have ecological deficit.1.14 hm~2 ecological footprint is needed for each person.The supplies of the lands with better ecological service function such as farmland,grassland,water bodies and land for absorbing exhaust gas of fossil-fuel(CO_2) are great smaller than requirement,the biological production lands including forests are losing with rapid speed.Influenced by industrialization,the supply and requirement status of fossil-fuel is the key factor for influencing regional ecological footprints. |
