基于能值生态足迹的浙江省可持续发展分析

ANALYSIS ON SUSTAINABLE DEVELOPMENT OF ZHEJIANG PROVINCE BASED ON ENERGY ECOLOGICAL FOOTPRINT METHOD

应用能值分析和本地生态足迹对传统的生态足迹方法进行改进,将可更新资源和社会生产消费中的能量流换算成对应的生物生产性土地面积。对本地生态足迹的计算方法进行了优化,即对消费账户进行了贸易修正,更贴近实际。经过计算,得出浙江省2007年的人均生态承载力为1.174 1hm2,人均生态足迹为3.946 2hm2,人均生态赤字为2.772 1hm2,万元GDP生态足迹为1.063 2hm2。根据计算出2000～2008年的各项指标,进行时间上的纵向比较,分析其变化趋势。又以2007年为基准,与部分区域的相关指标进行横向比较,进而分析了浙江省的可持续发展状况。最后,结合浙江省实际,提出了发展雨水收集、潮汐能开发等新的资源能源利用模式,鼓励节约能源,大力发展林木及林产品加工产业、水产品养殖及加工产业,并对浙江省较高的资源利用效率进行了评价。

By employing energy analysis and local ecological footprint method,this paper attempts to improve the traditional ecological footprint method with a proposal of transferring energy flows in renewable resources and social consumption to the corresponding biological productive units.In this paper,the calculation of the local ecological footprint method was optimized.That is,consumption accounts was revised considering of trade so as to be close to reality.The paper worked out that the ecological capacity per capita of Zhejiang Province in 2007 was 1.174 1 hm2.The ecological footprint per capita was 3.946 2 hm2.The ecological deficit per capita was 2.772 1 hm2 and the ecological footprint of per 1×104 yuan GDP was 1.063 2 hm2.This paper also conducted a vertical comparison of the indicators from the year of 2000 to 2008 so as to illustrate its development trend.Taken as a standard,the indicators of 2007 were compared with those in some regions with the further effort to expound Zhejiang＇s sustainable development.With calculation and the reality of Zhejiang Province,new resources use models like rain collection and tidal energy exploitation were put forward in this paper.It was encouraged to save energy,and advised to develop forestry and processing of forest products and to develop aquatic products breeding and processing.Resource utilization efficiency of Zhejiang Province was considered high.
