淮河生态经济带土地城镇化水平与质量协调度区域差异分析

REGIONAL DIFFERENCE OF LAND URBANIZATION LEVEL AND QUALITY COORDINATION IN HUAI RIVER ECO-ECONOMIC ZONE

以淮河生态经济带的20个地级市为研究对象,以其2010—2015年的土地及社会经济面板数据为基础,运用熵值法、综合评价模型和协调度模型等对土地城镇化水平和质量进行测度,并对两者之间的协调度进行评价分析,以期为指导淮河生态经济带土地城镇化健康发展提供依据和参考。研究表明,淮河生态经济带土地城镇化水平与质量均呈整体上升、局部波动的变化趋势,波动主要是部分地区大幅度的行政区划调整造成的;土地城镇化质量表现出生态质量所占比例不断下降的变化趋势。淮河生态经济带土地城镇化水平与质量协调度整体上呈现逐年上升趋势,协调度等级由勉强协调逐步向高度协调过渡,上升速度先快后慢;协调度的省际差异与发展水平的差异基本相似,且差距随发展水平提高而逐步缩小;地市间差异较明显,规划确定的核心城市协调发展状态不佳,不利于城市职能和辐射作用的发挥。

This paper,based on a case study on 20 prefectures along Huai River eco-economic zone,uses their socialeconomic panel data from 2010—2015 as basis and applies entropy,comprehensive evaluation model and coordination model to measure land urbanization level and quality,and evaluates their coordination in order to give references for the healthy development of land urbanization of Huai River eco-economic zone. The result shows a rising but fluctuating land urbanization level and quality,due to substantial administrative adjustment. Land urbanization quality displays a decreasing ecological quality trend. Their coordination also is rising yearly, from poor coordination to high coordination,fast and then slow in rising rate. The provincial coordination difference and development level difference are quite similar and become small as development level rises,while the regional difference is outstanding,coordination of designed core cities is not good,unfavorable for performing urban function.
