摘要
为促进干旱区城市可持续发展,以乌鲁木齐城市系统为例,基于2004和2010年统计数据,利用相图法分析得出:2003和2009年系统对不可更新自然资源的利用比例极大,对可更新自然资源利用比例最小;6年间系统对自然资源利用比例下降,尤其对可更新资源利用比例下降显著,为33.84%,而社会反馈投入能值比例上升;两年系统虽都处于可持续发展状态,但可持续发展指数有所下降且均接近下限。欲提升系统可持续发展性能,必须合理调整其能值利用结构。
For the sustainability of city system in arid area, taking Urumqi draws some conclusions from the emergy point of view by means of ternary as a case diagram study, the paper based on statistic data. In the two yeas of 2003 and 2009, the percent of un-renewable natural resource is the maximum of the city and the renewable ones, the minimum. The percent of natural resource declines in 2009 compared with that of 2003. Especially renewable ones falls 33.84%. However, that from society feedback is in ascending direction. Though the development of city system is sustainable both in 2003 and 2009, the sustainability index is less and less. They both approach to the lower limit of the ternary diagram field. In order to advance the sustainability of Urumqi, its emergy makeup of input has to be adjusted.
