摘要:

基于溧水县域1978—2008年遥感图像,从城镇实体地域扩展的视角,结合GIS技术分析县域尺度城镇空间格局演变特征,运用因子分析法探讨县域空间格局演变的动力机制。研究结果表明:1)近30年县域城镇用地扩展了2445 km2,年平均扩展速度为1854%,扩展强度指数为089,空间格局的演变划分为低速扩展期(1978—1989年)、增速扩展期(1989—2001年)与快速发展期(2001—2008年)3个阶段;2)从圈层和方位两个尺度分析得出城镇用地具有“单峰型”的演变特征以及向北、东扩展的方向性特征;3)县域城镇空间格局演变的三大主要驱动力因子为城镇人口增加、经济增长和产业结构调整。

Abstract:

This paper, based on Lishui county 1978-2008 remote sensing images, viewing from city expansion perspective, uses GIS technology to analyze the spatial pattern evolution in Lishui county, and applies factor analysis to study its mechanism of evolution. The urban land has been extended by 24.45 km2 in 30 years with an annual rate 18.45% and an expansion strength index 0.89. The spatial pattern evolution is classified as slow expansion period (19781989), accelerating expansion period (1989-2001), and fast expansion period (2001-2008). The urban land use bears an evolutional feature of “single peak” and north-& east-expanding direction. The three major driving forces are population growth, economic development and industrial structure adjustment.

Key words: urbanization, spatial pattern evolution, mechanism, county-scale, Lishui county
