基于协调度模型的经济快速发展区城镇土地集约利用评价

应用协调度模型原理,以广州市番禺区为例,进行了研究区城镇土地集约利用协调发展驱动机制探讨。结果表明,研究区城镇土地集约度为0.338 9,属于基本集约利用方式;经济、社会和生态系统协调度为0.130 7,处于严重失调状态;经济、社会和生态系统协调发展度为0.254 6,属于中度失调衰退经济驱动类型;各镇街城镇土地集约度、协调度、协调发展度和集约度协调发展驱动机制空间分异显著。

Urban Land Use Intensive Evaluation Based on Coordination Degree Model in Rapid Urbanization Region

In this paper,we took Panyu District of Guangzhou City,China as an example,and applied the principle of coordination degree model to explore the driving mechanisms of coordinated development of intensive urban land use.Results indicate that Panyu is in the base intensive use stage with an urban land use intensity index of 0.338 9.The region is seriously imbalanced among economic,social and ecological systems because their coordination index was only 0.130 7.Coordinated development index among economic,social and ecological systems was 0.254 6,placing it to the moderately imbalanced recessional economy-driven type.Urban land use intensity,coordination,coordination development and intensity coordination mechanisms varied greatly among subregions or towns.
