| 摘 要： | 利用TM影像、DEM、温度和降水等气象监测数据,提取了影响自然生态环境的5项重要指标:植被指数,海拔高度,土地覆盖,年均温和降水量。根据这5项环境指标,建立综合自然生态指数模型,并利用该模型对研究区进行环境评价,将研究区的自然环境划分了3级。结果表明该方法能有效地适用于研究区自然生态环境的评价。

| Abstract: | According to TM images,DEM,temperature and annual rainfall data from the observatory monitoring center,five significant indices affecting eco-environments are abstracted,including vegetation,altitude,landuse,temperature and annual rainfall.Based on these indices,an integrated evaluation model of eco-environmental quality is developed and applied in studying the water transfer project of Yalongjiang River.The studied region is evaluated and divided into three grades.The results show that this approach can be an effective method for evaluating the study region. |
