摘要: 利用探索性空间数据分析,通过构建城乡发展水平指数和耦合协调度函数等,对塔里木盆地42县市2004-2014年10年间城乡发展时空演化过程进行分析,得到以下结论:1)研究时段内塔里木盆地城乡发展水平有所上升,但仍处于低水平状态;格局为东高西低、北高南低,和田地区为发展"塌陷区"。2)耦合度总体呈波动状态,克州始终属于耦合度较低区域,巴州一直保持在高值状态,和田市及于田县耦合度下降最快;协调度10年间总体呈上升趋势,仅有少数地区呈波动或下降状态。3)耦合协调度存在空间正相关,高值集聚和热点区主要位于库尔勒市附近,低值集聚和冷点区主要位于喀什和和田两地区交界处;在2004-2009年和2009-2014年两个研究时段,格局基本维持不变。建议从基建投入、产业优化、教育投入等方面着手以改善区域城乡发展格局。

Abstract: The level of urban and rural development and its degree of coupling and coordination affect regional social stability. In this study we construct the urban and rural comprehensive development level index, and use the exploratory spatial data analysis method (ESDA) to analyze the spatial and temporal evolution process of urban and rural development in the 42 counties and cities in Tarim Basin from 2004 to 2014. The main conclusions are shown as follows. 1) The urban and rural development level of the basin increased during the study period, but it is still low; and the characteristic of the development level was high in the east and south and low in the west and north. 2) Coupling degree (Ccoupling) was generally fluctuating:Kizilsu was always in a low coupling area, Bayangol was in a high-value state, and the Ccoupling of Hotan City and Yutian County reduced at the most rapid speed. The coordinated development degree (Ccoordination) was generally on the rise and was fluctuating or declining only in a few areas. 3) The Ccoordination was spatially positively correlated, the high-value agglomeration and hotspots were mainly located near Korla, and the low-value agglomeration and cold-spot areas were chiefly located at the junction of Kashgar and Hotan. The pattern of the low-value agglomeration and cold-spot areas remained basically unchanged during the two periods between 2004-2009 and between 2009-2014. This study finally proposes to improve the development pattern in the aspects of infrastructure investment, industrial optimization, education investment, embedded development, and social stability.

Key words: urban-rural development, coupling coordination degree, spatiotemporal pattern, Tarim Basin
