摘要: 本文以扬州市市辖区为例,利用2001年的ETM影像与2007年的ALOS影像两期遥感数据,采用面向对象的信息提取方法,获取了扬州市2001年与2007年两期土地利用空间分布图。在此基础上,研究了CLUE-S模型的原理及CLUE-S模型的应用;探讨了CLUE-S模型所需数据、驱动因子选取、模拟参数设置、模拟结果获取等,进而运用CLUE-S模型,以2001年土地利用分布图为模型输入数据,模拟预测了扬州市2002-2007年的土地利用空间分布格局;最后,利用面向对象方法所获取的2007年土地利用空间分布图,对2007年的模拟结果进行了检验,研究分析CLUE-S模型的可应用性。结果显示,CLUE-S模型可以较好地模拟较小尺度区域城市空间发展分布格 局,能为较小尺度城市的发展规划提供指导,是值得推广应用的土地利用与土地覆被变化模型。

Abstract: Based on the principle of the CLUE-S (the conversion of land use and its effects at small region extent) model, taking Yangzhou City area as an example, we firstly collected the required data, including basic geographic data (vector data and image data) and statistics data, then preprocessed the image data, including ETM images in 2001 and ALOS images in 2007, and took use of object-oriented information extraction method to obtain a land use map for two periods (2001 and 2007). We selected the driving factors and used GIS spatial analysis tools to get a variety of spatial distribution of all the driving factors, set the model parameters, and took the land-use map in 2001 as the model input data to simulate the spatial pattern of land use of 2002-2007 in Yangzhou City area. Finally, we obtained the actual land use map of 2007 in Yangzhou City area by using the object-oriented data extraction method, and tested the simulation results of 2007 in Yangzhou City area and analyzed the applicability of the CLUE-S model. The result shows that the CLUE-S model could simulate preferably the spatial distribution pattern on a small-scale. Therefore, it could provide guidance for small city planning. So the CLUE-S model is one of the land use/land cover change models that worth to be made more widespread.
