为提高矢量化效率并减小勾绘误差，提出一种利用NDVI自动提取植被信息方法。利用NDVI与植被覆盖度之间的关系，自动提取不同覆盖度的植被信息。为检验方法的效果和效率，选取西藏某地区的TM影像进行植被提取实验，结果显示，与常用生产方法相比，本文方法能有效提高植被提取中的边缘勾绘速度和准确度。专业词语请查询cnki

To improve the efficiency and reduce the vector quantization error, criticize NDVI proposed using automatic extraction method of vegetation information. Using the NDVI and vegetation coverage, the relationship between different vegetation coverage of the automatic extraction. Test method for selecting the effectiveness and efficiency in a certain area of Tibet, TM images are extracted, and the results showed that the vegetation, and the experimental method, this paper compared commonly production method can effectively enhance the vegetation of edge criticize speed and accuracy
应该对的，看看给分吧
