基于 SLEUTH 模型的主体功能区划分后的土地利用变化

摘要

为解决区域问题,该文提出一种基于SLEUTH(slope land use exclusive layer urbanization transportationhillshade)模型的主体功能区划方法,可以根据土地利用的变化趋势对已划分好的主体功能区进行适当调整.以快速城镇化典型区苏锡地区为例,运用SLEUTH模型对已划分好的主体功能区从2009-2030年在不同情景下进行模拟,直观地反映出主体功能区划对土地利用变化的影响,据此对初次划分中由于条件模糊而难以判断的部分区域进行调整和优化,从而得到苏锡地区完整的主体功能区.结果表明该方法使主体功能区划具有直观的预测性和可调整性.该方法为合理实施主体功能区划提供技术性保障.%To provide feasible methods for solving region problems, a major function oriented zoning (MFOZ) method based on SLEUTH (slope, land use, exclusive layer, urbanization, transportation, hillshade) was proposed in this paper, which can adjust the MFOZ according to the tendency of land use change. Taking Suzhou-Wuxi region as research object, a typical rapid urbanization area, SLEUTH model was applied to simulate primary regionalization scenarios from 2009 to 2030, describing the land use change after MFOZ. Then ambiguous regions during the first zoning due to fuzzy conditions were adjusted and optimized and complete MFOZ in Suzhou-Wuxi region was obtained. The result showed that this method made MFOZ intuitively predicable and adjustable. Thus this method provides a technical supportive for reasonable implementation of MFOZ.
