应用遥感监测技术分析扬州市五年植被覆盖状况

利用扬州市2006—2010年间卫星遥感数据,对扬州市植被覆盖状况进行了研究。首先对遥感影像进行几何校正,其次对遥感影像进行解译,提取植被覆盖信息,计算扬州市植被覆盖指数,同时对扬州市近5年植被覆盖进行了动态变化分析。研究表明,扬州市近5年林地面积大幅度提高,植被覆盖指数逐年增加,生态环境状况逐年好转。

Analysis of theVegetation Coverage Condition in nearly Five Years in Yangzhou using Remote Sensing Monitoring Technology

Using the remote sensing data of Yangzhou in recent 5 years ,study on the condition of vegetation coverrage have been carried out. First of all ,geometrical correction of the remote sensing image; then, interpret these remote sensing images, extract the information of vegetation coverage and calculate the index of vegetation coverage. At the same time, the dynamic variation analysis for the condition of vegetation coverage for nearly five years has been studied. Research shows that forestry area is greatly improved in five years, and vegetation coverage index is increasing year by year .So the ecological environment situation of Yangzhou is getting better gradually.
