摘要
城市基础设施系统效益贡献度评价是城市基础设施长效性研究的重要组成部分,科学的评价为基础设施建设提供依据。在分析城市基础设施效益的基础上,设计涵盖社会、经济及生态环境效益等方面的基础设施效益贡献度指标,利用灰色关联分析法,以长江三角洲S城市为例,对其基础设施效益贡献度进行综合评价,结果表明研究时期内该城市基础设施系统效益贡献度总体上处于波动状态。整合人才、资本等各种资源,调整、优化投入比例和投入方式,采用科技手段提高能源利用效率,改变基础设施高投入、高消耗的建设运营模式是提高其贡献度的有效手段。研究基础设施效益对城市发展的贡献程度有助于引导基础设施科学的建设和城市的可持续发展。
The benefit contribution evaluation of the urban infrastructure systems is an important part of the sustainable development research, which is an instruction for infrastructure construction. Based on the analysis of the benefit of urban infrastructure, contribution index considering society, economy and biography was designed. Gray correlative analysis was employed to make evahration for the contribution of benefit of urban infrastructure. City ＂S＂ was taken as an example and the evaluation results showed that in the duration researched its contribution was in fluctuation, and adjustment and improvement of the resource investment ratio was the effective way to raise the contribution. The research on the contribution of benefit of infrastructure to urban development is helpful to scientific decision： making and management of infrastructure construction and sustainable development of the city.
