基于高分辨率遥感影像的张店区土地利用变化研究

Research on land use change of Zhangdian District based on high resolution remote sensing image

以2011年、2013年WorldView-2和2016年GF-2高分辨率遥感影像作为数据源,通过面向对象多尺度分割、分层提取的方法获得山东省淄博市张店区2011年、2013年和2016年土地利用类型图,并采用叠加分析的方法获得土地利用类型变化矩阵.研究表明,张店区2011年到2016年建设用地和道路用地的增加主要来源于耕地.城市扩张的代价是耕地的不断减少,在耕地资源严重不足的现状下,城市发展应当处理好人地关系,实现土地资源的可持续利用.

This paper chooses World View-22011,2013 and GF-2 2016 high resolution remote sensing image as a data source and uses object-oriented multi-scale segmentation method and hier-archical extraction method to obtain the land use type map of Zhangdian district in 2011,2013 and 2016.Then the transition matrix of land use type of Zhangdian district is extracted by the means of overlay analysis.The results show that the land for construction and roads in Zhangdian district in 2011 and 2016 mainly come from cultivated land.The speeding-up of urbanization process is at the cost of decreasing farm land.Therefore under the serious land shortage situation, it is necessary to handle the relationship between human and land during the development of ur-banization.Only by this can sustainable utilization of land resources be realized.
