| 摘 要： | 准确判别城市扩展规律、剖析演化过程,对于预测城市未来演化趋势、制定合理的调控政策具有重要的意义。本文以1990年、2000年、2008年和2012年4个具有代表性年份的卫星影像为依据,应用RS和GIS手段提取了北海市城市实体边界,分析了该市扩展空间特征、面积、方向和速度。研究结果表明:22年间北海市城市实体加速扩展,但其建成率基本不变,这种变化反映了城市规划、宏观调控、海岸带利用政策以及交通对城市扩展的影响。

| Abstract: | For the purpose of predicting the future urban evolution trends and elaborating rational policies for regulation and control, it′s significant to distinguish correctly the rules of urban expansion and to analyze the evolution process.Based on the satellite images of 1990, 2000, 2008 and 2012,the article applied RS and GIS to extract the boundary of physical urban area of Beihai and analyzed the leading rules of the characteristic, area, direction and rate.It′s indicated that expansion of physical urban area of Beihai devel-oped rapidly in recent 22 years, and the rate of city build-up area is basically unchanged, this change of urban expansion influenced by urban planning, macroscopic readjust and control, the policy of exploit of coastal zone and traffic circulation. |
