新疆城镇化与生态环境耦合协调发展时空区域差异评价研究

摘要

15 regions in Xinjiang was taken as an example .The evaluation index system of urbanization and eco-logical environment was constructed based on the statistical data of urbanization and ecological environment from 2004 to 2014 .The urbanization and ecological environment space-time evolution of coupling coordination was revealed through the coupling coordination model and geographic information system .The results showed that :(1) In 2004-2014 ,the comprehensive level of urbanization of the 15 areas showed the rising trend ,except for the individual regions of individual years .The comprehensive index of ecological environment presented a fluctuating rising trend .(2) In terms of time series ,the coordination degree showed upward tendency ,and there was no sudden change in grade .(3) The spatial pattern of the coordinated development of urbanization and ecological environment of Xinjiang was charac-terized by great geographical variations ,coordination degree of north regions was higher than that of south regions .%以新疆15个地 、州 、市为例,采用2004—2014年城镇化与生态环境统计数据,构建城镇化与生态环境评价指标体系,通过耦合协调度模型和地理信息系统来揭示城镇化和生态环境耦合协调时空演化规律.结果表明:(1)2004—2014年,新疆15个地 、州 、市中,除个别地区个别年份城镇化综合指数出现回落现象外,总体呈上升趋势;生态环境综合指数呈波动上升趋势.(2)在时间序列角度,协调度体现向上趋向性,没有明显的等级跳跃.(3)新疆城镇化和生态环境协调发展空间格局特点是地域差异很大 、北疆水平高于南疆.
