摘要
研究目的:构建城市用地效益评价模型与评价指标体系,对2000—2004年浙江省11个地级市的城市用地效益进行综合评价。研究方法:加权平均法,秩相关系数,聚类及GIS分析法。研究结果:(1)秩相关分析表明,2000—2004年,浙江省城市用地综合效益呈上升、协调度呈下降趋势,而11个地级市则呈不同变化趋势;(2)城市用地综合效益、单项效益及协调度之间的关系呈多样化;(3)城市化水平与综合效益、单项效益及协调度之间关系不显著;(4)应用聚类与GIS分析法,将11个城市分为高效基本协调、中效协调、中效基本协调、低效基本协调和低效不协调5类。研究结论:浙江省城市用地整体状况良好,空间变异分析结果基本符合浙江省块状经济特色,同时,浙江省的城市化过程应追求量与质的共同提高。
The purpose of the paper is to establish a evaluation system on ULCB （urban land comprehensive benefit） by comprehensively evaluation on 11 cities＇ ULCB of Zhejiang Province from 2000 to 2004. Methods employed included weighted average, spearman rank relational coefficient, clustering and GIS analysis. Results show： （1）during the five years from 2000 to 2004, the change tendency of ULCB and harmony degree in Zhejiang Province indicate up and down respectively, and the tendency is different in 11 cities, however; （2）the relationship between ULCB, monomial benefit and harmony degree is diversified;（3 ）the ULCB, monomial benefit and harmony degree have no significant relationship with the urbanization level;（4）it reveals from the clustering and GIS analysis that those 11 cities can be divided into 5 classes, such as high benefit and basic harmony, medium benefit and high harmony, medium benefit and basic harmony, low benefit and basic harmony and low benefit and basic harmony. It is concluded that, as a whole, the land use condition in Zhejiang Province is sound, and the analysis on spatial variance witnesses specific characteristic of ＂industrial clusters＂ of Zhejiang economy, but the quality of urbanization should be improved in the future.
