摘要
基于三维生态足迹模型,测算了2011—2015年福州市人均足迹广度、深度和三维生态足迹.结果表明,2011—2015年福州市的人均足迹广度、深度和三维生态足迹均呈现"减—增—减"的变化趋势.福州市人均足迹广度由0.2384 hm2降低到0.2319 hm2,降低了2.7%,耕地是人均足迹广度的主要构成部分,占比达到40%以上;人均足迹深度由7.8907降低至6.9480,降低了11.9%;三维生态足迹由1.8810 hm2降低到1.6109 hm2,降低了14.4%.虽然2011—2015年福州市的生态赤字也有所下降,但其数值依然较高.总体看来,福州市的可持续状态发展仍不容乐观.最后结合该地区特点提出了一些科学合理的对策,以维持福州市的可持续发展.
Abstract
The ecological footprint theory is an important way to analyze the regional ecosystem balance and sustainable development .Based on the Three-Dimensional Ecological Footprint Model, the per capita footprint size, footprint depth and three-dimensional ecological footprint of Fuzhou from 2011 to 2015 were calculated.The results show that:the per capita footprint size, footprint depth, and three-dimensional ecologi-cal footprint of Fuzhou city during 2011 to 2015 decreased first, and then increased, and decreased again.The per capita footprint size de-creased from 0.2384 hm2 to 0.2319 hm2, decreased by 2.7%, the cultivated land was the main composition of per capita footprint size, ac-counted for more than 40%.The per capita footprint depth decreased from 7.8907 to 6.9480, decreased by 11.9%.The per capita three-dimensional ecological footprint decreased from 1.8810 hm2 to 1.6109 hm2 , decreased by 14.4%.The ecological deficit of Fuzhou decreased in 2011-2015, but it was still high.The situation of sustainable development in Fuzhou was not optimistic .Finally, in order to maintain the sustain-able development of Fuzhou , some scientific and reasonable countermeasures were put forward according to the local characteristics .
