利用扬州市近5年的遥感影像,对扬州市生态环境质量进行了动态分析。通过对遥感影像进行几何校正,对遥感数据进行解译,提取土地利用/覆盖信息,计算了扬州市生态环境质量指数,研究了扬州市近5年生态环境状况动态变化趋势。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、生物丰度指数逐年增加,生态环境状况逐年好转。
利用颺州市近5年的遙感影像,對颺州市生態環境質量進行瞭動態分析。通過對遙感影像進行幾何校正,對遙感數據進行解譯,提取土地利用/覆蓋信息,計算瞭颺州市生態環境質量指數,研究瞭颺州市近5年生態環境狀況動態變化趨勢。研究錶明：颺州市近5年林地麵積大幅度提高,植被覆蓋指數、生物豐度指數逐年增加,生態環境狀況逐年好轉。

Based on the remote sensing Image of Yangzhou in recent 5 years,this paper makes a aynamlc a- nalysis of the ecological environmental quality in Yangzhou City. First of all,it makes the geometric correc- tion of remote sensing image,and then,interprets these remote sensing images, extracts the information of vegetation cover, calculates the index of ecological and environmental quality, and at the same time studies the condition of the ecological and environmental quality in nearly five years. The research shows that the woodland areas Substantially increase in the past five years in Yangzhou City, the vegetation cover index and biological abundance index increase year by year,and the ecological environment situation gets better year after year.
