20世纪90年代以来沈阳市人口、经济、空间与环境的协调度分析

在中国城市化迅速发展的背景下．城市人口、经济、空间与城市环境的矛盾日益复杂和激化，从可持续发展的角度出发．迫切需要研究城市人口、经济、空间与城市环境之闻的协调关系。运用主成分分析和回归分析等方法。在市区尺度上构建城市人口、经济、空阃与城市环境的协调评价体系，并以老工业城市沈阳为例，进行实证分析。分析结果表明：沈阳城市人口经济空间的综合发展于1993—1999年处于困境．2000年以后城市综合发展逐步好转；沈阳城市环境在1998年以后稳定上升；沈阳城市综合发展与城市环境的静态协调度具有明显的阶段性和波动性特征，动态协调度具有平滑和滞后性的特点；静态协调度于1993—1994年属于基本不协调阶段．1995—2005年基本处于协调状态。于1999年出现了低谷。并存在着下降的趋势；动态协调度于1993—1996年属于基本不协调阶段。1997年以后总体上属于基本协调阶段。

Coordination Degree of Urban Population, Economy, Space and Environment in Shenyang Since the 1990s

In the background of the rapid urbanization, the conflict between urban population, economy, space and environment are intensified and appear complexity. The coordinate assessment system of urban population, economy, space and environment is established in the scale of urban size by principal component analysis and regression analysis, etc.. The demonstration analysis took Shenyang as an example. The result indicated the integrated development of urban population, economy and space in a poor occasion during 1993 and 1999, which turned better after 2000, and the urban environment improved after 1998. The static coordination degree of urban integrated development and environment showed obvious stage and fluctuant characteristic, and the dynamic coordination degree appeared smoothness and lag. The static coordination degree was not coordinative from 1993 to 1994, which turned to be coordinate between 1995 and 2005, and it dropped to the bottom in 1999 with the falling down trend. The dynamic coordination degree was not coordinate from 1993 to 1996, and became coordinate after 1997.
