摘　　要：指出了植被覆盖度是一个十分重要的生态气候参数,是植物群落覆盖地表状况的一个综合量化指标,研究植被覆盖度的估算及其变化,对生态系统环境变化起重要作用,也对水文、生态、全球变化等领域都具有重要意义。介绍了植被覆盖度遥感测量方法的基本理论、研究现状和发展趋势,以TM影像为数据源,利用ENVI 5.0遥感处理软件,结合地面调查数据,分析了济南市南部山区遥感影像的植被覆盖度估算结果,利用像元二分法进行了植被覆盖度的反演,为进行大面积植被覆盖度估算提供了一种有效的途径,且基本能够满足生态环境及气候变化研究的要求。Vegetation coverage（the ratio of vegetation＇s vertical projection area and unit area） is an important eco--cli- matic parameter, which is a comprehensive quantitative indicator for measuring the condition of vegetation. The arti- cle studies on the estimation and changes of vegetation coverage, whichplays an important role in the ecosystem envi- ronment＇s change and also has a great significance on hydrology, ecology, global change, etc. This articleintroduces the situation of current research status and the developing trend, as well as the basic theory of the methods formea- suring vegetation coverage. Adopting TM image as the data source and ENVI 5.0as processingsoftware and combi- ning with the ground survey data, the article takes Ji＇nan city as an example to analyze the vegetation coverage＇s esti- mated results of the southern mountain area. Through the inversion of vegetation coverage by dimidiate pixel model, the article provides an effective way to estimate the vegetation coverage on a large area, which can meet the basic re- quirements of the study on the ecological environment and climaticchange.
