基于社会生态系统代谢多尺度综合评估(MuSIASEM)理论,对2000—2007年大连经济技术开发区人类活动时间、体外能投入量和增加值进行综合评价.结果表明:2000—2007年,大连开发区居民生活水平逐年提高;农业逐渐萎缩;第二产业仍为区域支柱产业,能耗较大;第三产业发展落后于第二产业;区域整体和各个产业的体外能代谢率明显提高,能源密度不断下降;人类活动时间与体外能投入量不断减少的情况下,经济增加值稳步增长,区域整体发展呈可持续态势.
Based on the theory of multiple-scale integrated assessment of societal and ecosystem metabolism(MuSIASEM),a comprehensive evaluation was made on the human activity time,exosomatic energy input,and added value of Dalian Economic and Technological Development Zone in 2000-2007.During the study period,the life quality of local citizens increased year after year,while the agricultural industry dwindled.Manufacturing industry was still the main pillar industry,but its energy consumption was greater.Service industry was at its early stage,falling behind manufacturing industry.The exosomatic metabolic level of the whole zone and its various industries had an obvious increase,and the energy intensity decreased continuously.With the fact that both the human activity time and the exosomatic energy input had a ceaseless decrease,the economic added value increased steadily,and the zone was under its way towards sustainable development.
