摘要

本文根据Landsat TM影像数据磁带和地面实况调查资料

提出了洪水期影像的解译方法

并以肖家湖实验区为例

解译了该区洪水期的影像。通过监督分类和非监督分类估算了洪水淹没范围;根据比值植被指数图像解译出了不同受灾程度作物的分布;用NDVI计算作物的受灾损失

并对结果进行了讨论。

Abstract

Based on the landsat TM image data and the ground truth

the interpretation method is developed in this paper. In the case of Xiaojiahu Region

the image of flooding period is interpreted. The inundated area is estimated by supervised and unsupervised classification; the distribution map of crop damage content is made in terms of RVI; the crop losses are estimated from the calculation of NDVI; and the results are discussed in detial.
