珠三角城市经济与环境协调关系的时空演变
Spatio-Temporal Evolvement of Coordinated Relationship between Urban Economy and Environment in the Pearl River Delta

基于2000、2005和2010年一系列经济和环境指标数据,运用协调度模型和协调发展度模型及GIS技术,分析了2000—2010年珠三角地级城市经济与环境协调发展关系的时空演变． 结果表明：（1）珠三角整体经济与环境的协调度和协调发展度先有所降低后明显提升,在整个研究期内呈上升态势,即经济与环境协调状况和协调发展水平总体上得到改善;（2）各城市协调度值和协调发展度值有升有降、表现各异,但层次性分明． 近一半城市的经济与环境协调发展类型相对稳定,其他城市协调发展类型发生了一定的转化;（3）城市经济与环境协调发展水平总体上呈“核心-外围”结构,且城市间总体空间差异先有所扩大后明显缩小． 三大地带城市经济与环境协调发展水平的不均衡性明显,东部与中部差异逐步缩小,而西部与中、东部的差异先扩大后缩小．
： Based on a series of economic and environmental data of 2000, 2005 and 2010 in the Pearl River Delta, and using coordinated degree model, coordinated development degree model and GIS technique, the spatio-temporal evolution of coordinated relationship between urban economy and environment at prefecture level from 2000 to 2010 is analyzed in this paper. The results show that(1)The whole coordinated degree and coordinated development degree between urban economy and environment in the region first descended and then ascended obviously, but had a rising trend from 2000 to 2010, i.e., the coordinated status and coordinated development level of economy and environment were improved as a whole. (2)The coordinated degree and coordinated development degree of each city went up and down frequently but had obvious grade-layers. The coordinated development types of about half of cities kept stable, however, those of the rest involved certain transformations. (3)The coordinated development level of urban economy and environment showed a core-periphery structure as a whole, and the overall spatial difference between cities first expanded and then decreased significantly. The imbalance of the coordinated development level of economy and environment among the three zones was obvious, and the disparity between the eastern and central zones gradually decreased, whereas the disparity between the western zone and the central and eastern zones first expanded and then decreased
