徐州市土地利用CLUE-S模型变化模拟

对徐州市1987年、1994年和2000年3期遥感影像图进行分析,利用面向对象的思想,采用多尺度分割法对影像进行分类,通过遥感影像的光谱特征,确定分类目标,获取该区过去13年间的土地利用/覆被时空变化特征。运用CLUE-S模型以1994年土地利用数据模拟了2000年的土地利用空间变化状况,并通过2000年实际遥感影像分类数据加以验证,结果计算出Kappa指数为0.846,达到精度要求,实例证明CLUE-S模型较好地模拟了徐州市的土地利用/覆被变化。最后运用CLUE-S模型以6年为1个时空尺度模拟该区未来12年的自然状态和生态保护状态下的土地利用/覆被变化特征。

CLUE-S Model of Land Use Change Simulation of Xuzhou City

In this paper,through analysis three remote sensing image of 1987,1994 and 2000 in Xuzhou City,using object-oriented method,and multi-scale segmentation of the image classification,spectral remote sensing images to determine the classification of targets,accessed to the area in the past 13 years of land use/cover spatial and temporal variation.The use of CLUE-S model to simulate 1994 land used data in 2000 changing the land status of the use of space,and by 2000,the actual classification of remote sensing image data to be verified,the results to calculate the Kappa index of 0.846 to achieve accuracy,examples proved that CLUE-S model can simulate the XuzhouCity Land Use/Cover Change.Finally,the use of CLUE-Smodelwith6yearsas aspace-time scale modeling in the area over the next 12 years,the state of nature and ecological protection under the Land Use/Cover Change.
