| 摘 要： | 分析覆盖地物的遥感光谱响应特性对于利用遥感监测土地覆盖是非常必要的。基于GPS实地调查，利用ETM 数据，采用全数字化遥感定量方法对大中甸乡典型土地覆盖地物多波段光谱响应特性进行研究。结果表明，该区13种典型覆盖地物，同属于非植被类型与同属于植被类型覆盖地物所表现的响应特性曲线形态具有明显差异，NDVI表现出以数值0为分界限，大于0为植被地物，小于0为非植被地类；另外，光谱响应分析还应考虑遥感信息获取的时相特性。

| Abstract: | It is important to understand the multi -spectrum characteristics response for monitoring land cover by remote sensing. As a study in an area of northwest of Yunnan provi nce, which is based on field survey by GPS using ETM+ data from Landsat7 on Oct., 1999, the response multi-s pectrum values of the land cover objects in remote sensing image is measured and analyze d. lt is found out that thirteen differente types of land covers express differe nt characteristics in the multi-spectrum curve, and that the multi-spectrum curve of land covered with t hose without vegetation cover.When NDVI value is larger than zero,it repvesents the lands covered with vegetation,while NDVI is less than zero,it represents lands without vegetation. In addition the time feature of land cover response multi-spectrum is need to be considered in the analysis. |
