摘要
植被覆盖度是衡量地表植被覆盖的一个重要指标,在许多方面作为重要参数输入。根据像元二分模型原理和归一化植被指数,利用归一化植被指数(NDVI)定量估算植被覆盖度的模型可以求得研究区域的植被覆盖度。本文根据该模型对重庆市沙坪坝区进行了植被覆盖度的遥感估算,结果表明,该方法简单易行。
Vegetation fraction is a very important index to score the vegetation coverage on the land surface and is used in many aspects as one of the input parameters. Based on the dimidiate pixel model and the normalized difference vegetation index, the vegetation fraction of study region can be calculated by using the model of quantifying vegetation fraction from normalized difference vegetation. This paper calculated the vegetation fraction in Shapingba district of Chogqing by remote sensing based on this model ,the result showed that it was simple and available.
