分层土壤水分的遥感估算——以岷江上游毛儿盖地区为例

摘要

土壤水对于地球各层各种水分交换有着十分重要的意义.岷江上游地区地质地貌情况复杂,针对其特点,利用不同的植被指数与温度构造特征空间,比较分析后选用Ts-EVI空间建立的水分指数,反演适用于岷江上游典型地表的土壤含水量模型和地下土壤分层含水量模型.%Soil water is very important to water exchange in different strata of the earth. For the complex geological conditions in the upper reaches of Minjiang River, this paper builds a feature space using different vegetation indexes and temperatures, and, based on a comparative analysis, selects the moisture indexes established by Ts-EVI Space to establish the model of soil moisture content adaptive to the typical surface of the upper reaches of Minjiang River and the model of underground land moisture in strata.
