| 摘 要： | 植被覆盖度是一个十分重要的生态学参数,其对于全球环境变化和监测研究具有重要意义.为了有效地从遥感资料中提取植被覆盖度,在像元二分模型两个重要参数推导的基础上,对已有模型进行了改进,建立了用归一化植被指数(NDVI)估算植被覆盖度的模型.运用该模型对鄱阳湖区2003年的植被覆盖度进行了估算,通过鄱阳湖部分地区的实地考察,对2003年的植被覆盖度估算结果进行了验证,结果表明使用此改进模型进行植被覆盖度遥感监测是有效可行的.

| Abstract: | Vegetation fraction is a very important ecology parameter,and plays an important role in the change and observation of global entironment.Estimation of vegetation fraction from remote sensing data may be a very efficient approach.Based on two important parameters of discursion of dimidiate pixel mode,the current model is improved.The model of deriving vegetation fraction from normalized difference vegetation index(NDVI) is established.The vegetation fraction of the Poyang Lake Area in 2003 is estimated according to this model.The result of the on-the-spot-investigation confirms that it is feasible to use this improved model in estimation of vegetation coverage from remote sensing data. |
