台儿庄区25年土地利用/覆盖变化研究

研究土地利用/覆盖变化的规律和机制对认识人类活动在全球变化中的作用机制具有重要意义。利用1979年的MSS影像和2004年的TM影像资料，运用目视解译方法，获取土地利用信息，使用GIS软件的空间叠加分析功能，获取土地利用/覆盖变化数据。分析表明:在1979-2004年25 a间台儿庄区的土地利用/覆盖状况发生了显著变化，主要表现在农田、林地转变为居民地及其他用地，交通运输用地的增加；并且农田、林地用地的减少是区域内变化速度最显著的土地利用类型；土地利用的集约化程度一直在不断提高。加强耕地保护力度，合理控制建设用地规模，科学开展城市用地规划是确保今后台儿庄区土地可持续利用的合理途径。

Dynamic of Land Use/Cover Change During Recent 25 Years in Taierzhuang

Studying the features of land-use/cover change is important on the understanding of human activity in the mechanism of global change. The essay uses the MSS image (1979), the TM image data (2004) and the visual interpretation to obtain the information of utilizing the land of Taierzhuang and analyzes the characteristic of the changing in the past three decades. The results show that the change of land-using mainly focuses on: Use more land to build resident area or other uses than farming and forest, the increasing use of land for transportation. And also the most significant change of land using took place in the decreasingly use of farmland and forest within the district. The degree of intensification has been increasing. It is the reasonable method for enhancing the protection of arable land, controling the scale of construction, carrying on the program of urban development reasonably and scientifically to ensure the sustainable use of land in Taierzhuang district.
