一、符合土壤发生学理论作为遥感产品的航、卫片影像,是地面或地表以下一定深度的地物反射和发射电磁波,经传感器接收,光学或电算处理,在像片上的客观记录与反映。因此,它是地表形态(包括高差和阴影)植被(包括农业利用)、水文(包括地表水和地下水)和地表物质组成(岩石与土壤)等环境因素的综合反映,具有环境(或景观)因素的综合信息特征。而土壤正是环境诸因素综合作用下发生发育、演变,并与环境协调统一的自然产物。
First, in line with the theory of soil genesis remote sensing products, satellite imagery, is the surface or below the surface of a certain depth of reflection and emission of electromagnetic properties, the sensor receives, optical or computerized processing, the objective record on the film and reflect . Therefore, it is a comprehensive reflection of environmental factors such as vegetation (including agricultural use), hydrology (including surface water and groundwater) and surface material composition (rock and soil) in the form of surface (including elevation and shadow) Comprehensive information characteristics of factors. Soil is a natural product that develops, evolves and coordinates with the environment under the combined action of various environmental factors.
