摘要: 在分析1990年和1997年两个时相陆地卫星TM遥感图像的基础上,得到了厦门市土地利用/覆盖的动态变化信息,并对其数量变化和空间特征进行了分析。结果表明:1990~1997年,厦门市的城镇建设用地和开发用地显著增加,耕地被占用的现象比较突出,开发用地的重点也由厦门经济特区向近郊区转移。

Abstract: Remote sensing is an important approach for land use /cover change detection. With two phrases of remotely sensed images covering Xiamen City in 1990 and 1997 respectively, this paper applied Maximum Likelihood Classification and visual interpretation to obtain the land use/cover classification of seven categories, namely build-up, development use, transportation, arable land, garden and forest, water body and unused land. And the land use/cover change image was obtained via map algebraic calculation. The results show that resident area increased in a large amount from 1990 to 1997, while arable land decreased nearly at the same extent. The decreased arable land was mainly occupied by build-up, development use and transportation. In 1990, land used for development was mainly located in the Xiamen Island and amounted to 65 percent of the whole development land of the city, while in 1997, the percentage decreased to 30 percent which demonstrated that developing emphasis has shifted from down town to suburb in the 7-year period.
