基于作物水分胁迫指数的表层土壤含水率遥感估算
S161; [目的]探究作物水分胁迫指数(CWSI)与表层土壤含水率的空间分布特征,并分析不同下垫面(葵花、夏玉米、春小麦和甜椒)表层土壤含水率的遥感估算精度.[方法]利用MOD16A2遥感数据和气象数据,结合Penman-Monteith(P-M)模型,基于CWSI反演河套灌区解放闸灌域表层土壤含水率,并对不同下垫面的表层土壤含水率进行验证.[结果]CWSI的空间分布与表层土壤含水率相反,CWSI大的区域,表层土壤含水率小;春小麦下垫面遥感估算的表层土壤含水率效果较好,决定系数(R2)为0.748,其次为葵花,R2为0.357;灌溉次数较多的夏玉米和甜椒的表层土壤含水率估算精度较差,可见基于...
