| 摘 要： | 以福建省厦门市集美区为例，分析集美区人口、经济、产业、用地景观等方面所表现出来的半城市化现象基本特征。并基于研究区1987～2007年5期TM／ETM＋遥感影像数据分析其20年土地利用时空动态变化特征及土地利用存在的问题。结果表明，集美区具有典型的半城市化地区的特征，20年间建设用地大量增加，耕地面积急剧减少。城市建设用地增长最快，其扩展主要是通过侵占耕地和未利用地；未利用地的增加主要来自耕地的转化。耕地主要流向建设用地、未利用地和林地。淡水水域被转化为建设用地和未利用地。耕地是在城市化过程中最容易受到侵占的土地利用类型。随着快速城市化的发展，半城市化地区的耕地、湿地（包括滩涂和近海海域）面积明显减少，致使其提供的生态系统服务功能降低，必将引起一系列生态环境问题，生态环境的恶化反过来又制约着经济的进一步发展．因此应重视半城市化地区土地利用的规划与管理，促进区域的可持续发展。

| Abstract: | Taking Jimei District of Xiamen as an example,the essential characteristics of semi-urbanization phenomenon in the aspects of population,economy,industry and landscape in Jimei District were analyzed.Moreover,based on No.5 TM/ETM+ RS image data during 1987-2007 in study areas,the characteristics of land use temporal and spatial dynamics changes and problems in land use in 20 years were analyzed,the results showed that Jimei District has the typical characters of peri-urban areas.During the past 20 years,it had a significant increase of construction land(urban and rural),meanwhile,farmland has decreased sharply.Urban construction land grew fastest,mainly through the expansion of its occupation of farmland and unused land.Unused land increased primarily from the conversion of farmland.Farmland mainly conversed to construction land,unused land and forestland.Farmland is most vulnerable to encroachment of land-use type in the process of urbanization.Freshwater areas are transformed into construction land and unused land too.With the rapid urbanization,the areas of farmland,and wetlands(including short sea area and mudflat) were significantly reduced,which will cause a series of ecological and environmental problems.And environmental deterioration,in turn,will restrict economical development.Analyzing the temporal and spatial characteristics of land-use change in peri-urban areas can provide its basis for scientific management of land resources and promote regional sustainable development. |
