【摘要】：在系统分析能值—生态足迹模型缺陷的基础上,通过增加人工投入指标,统一能值密度以及引入折能/折标系数对其进行了修正,并采用修正后的模型对江苏省南通市1996—2010年的可持续发展水平进行了测算。结果表明:(1)1996—2010年间南通市人均生态足迹由0.65hm2增长到0.90hm2,主要是由能源消费量的增加引起的;(2)同期南通市人均生态承载力由0.51hm2增长到0.81hm2,这主要是由农、畜产品产量提高和水电开发力度加大引起的,而通过劳务和资金投入提高承载力的空间很大;(3)1996—2010年南通市一直处于生态赤字状态,可持续性评价指数也都在0.5以上,区域发展处于不可持续状态。为进一步缩小生态承载力与生态足迹之间的差距,应采取以下措施:引导重点行业和企业节能降耗,大力发展新能源;加大农业科技投入,继续提高农产品产量;重视人力资源的投入,促使经济发展方式向技术密集型和资本密集型转变。
[Abstract]:On the basis of systematic analysis of the defects of the emergency-ecological footprint model, it is corrected by increasing the artificial input index, unifying the emergy density and introducing the folding / folding coefficient. The sustainable development level of Nantong City in Jiangsu Province from 1996 to 2010 was calculated by using the modified model. The results show that the per capita ecological footprint of Nantong city increased from 0.65hm2 to 0.90 hm2between 1996 and 2010, mainly caused by the increase of energy consumption. During the same period, the per capita ecological carrying capacity of Nantong city increased from 0.51hm2 to 0.81hm2.This was mainly attributed to agriculture. As a result of the increase in livestock product production and the increase in hydropower development, the space for raising the carrying capacity through labor services and capital input is very large. Nantong City has been in an ecological deficit from 1996 to 2010, and the sustainability evaluation index is also above 0.5. Regional development is in an unsustainable state. In order to further reduce the gap between ecological carrying capacity and ecological footprint, we should take the following measures: guide key industries and enterprises to save energy and reduce consumption, vigorously develop new energy, increase agricultural science and technology investment, and continue to increase agricultural product output; Pay attention to the investment of human resources, promote the mode of economic development to technology-intensive and capital-intensive transformation.
