构建基于CLUE-S与灰色线性规划混合模型的土地利用优化配置方法,在导入区域政策、社会经济、生态目标和土地利用现状等条件下,进行土地利用数量结构与空间布局的统一优化,并以嘉兴北部地区为例进行实证研究,共设置现状趋势情景、规划目标情景和规划可持续情景这3种模拟情景。规划可持续情景侧重社会经济环境效益,故对建设用地快速增长和农用地持续减少起到明显调控作用,可实现生态敏感区环境和粮食安全的双重保护,是理...
基于CLUE-S模型验证的海岸围垦区景观驱动因子贡献率
景观动态 主成分分析 驱动力贡献率 CLUE-S模型模拟
2011/10/20
基于1990、2000、2009年TM影像、社会统计数据、野外调查数据,采用冗余分析和主成分分析方法对长江口奉贤段围垦区海岸带景观动态变化驱动力因子的贡献度进行分析,并利用Kappa指数对CLUE-S模型所选驱动力模拟效力进行验证.结果表明:海岸带围垦区景观动态变化的人为驱动因子贡献度(57.1%)大于自然驱动因子贡献度(42.9%).CLUE-S模型模拟的正确率达82%,研究区主要景观类型(耕地...
