一、试验目的与方法本试验的目的是选择某些土壤类型与植被,测试及分析其所记录的反射能量与反射光谱曲线,为彩红外航片不同地物影象特征,提供可能的解释,并进一步提高判读精度.为此,在山东省陵县和禹城实验区土壤详查的基础上,于1982年5月及1984年5月,在陵禹地区选测各种地物光谱曲线34条.5月份天气晴朗,气候干燥,土壤含水量小,强烈返盐,植被较单一,除麦田、棉田及芦苇地之外,土壤大部裸露,有
Aims and Methods of Experiment The purpose of this experiment is to select some soil types and vegetation, to test and analyze their recorded reflection energy and reflection spectral curves, to provide possible explanations for the image features of different ground objects of Caihong Aero Film, And further improve the accuracy of interpretation.Therefore, based on the detailed investigation of soil in Lingxian and Yucheng experimental areas in Shandong Province, spectral curves 34 of various kinds of ground objects were selected and tested in Lingyu area in May 1982 and May 1984 In May, the weather was fine, the climate was dry, the soil had a small amount of moisture and returned to salt intensively with a relatively simple vegetation. Except for wheat fields, cotton fields and reeds, most of the soil was bare with
