咸阳市生态市建设的区域可持续发展水平研究

Study on Regional Sustainable Development Level of Xianyang Ecosystem Construction

从区域生态市建设的可持续发展能力评价角度,以咸阳市为例,构建区域生态市建设的可持续发展评价指标体系,采用均值化方法对指标进行无量纲化处理,并对指标体系中的"成本型"指标进行正相关处理,运用灰色关联分析法计算出可持续发展的关联度和关联系数.根据关联度的大小分析生态市建设不同规划阶段的可持续发展水平,根据关联系数分析制约生态市建设目标实现的瓶颈.结果表明,咸阳市可持续发展能力呈上升趋势,但有10项指标与最优值相差较大;针对咸阳市生态市建设中存在的不足提出了建设具体措施,以保证其可持续发展目标的实现.

Bases on evaluating the ability of sustainable development in regional ecological city construction, take Xianyang City for example, an evaluating index system was introduced. Those indexes are then made dimensionless by the way of averaging procedure and some cost indexes were handled by positive correlation process. Finally, the grey relational grade and grey relational coefficient were calculated by applying grey relational method. From the result, the different levels of ecological city sustainable development can be classified and the primary restriction can also be pointed out. The result of grey relational degree indicates that the sustainable development ability of Xianyang City is going better and better, and there are 10 indexes that have a great gap with the optimized ones. Then according to the results, the faults in Xianyang ecological city construction were pointed out and some countermeasures for realizing the goal of sustainable development drawn up.
