扬州市2010年-2015年生态环境遥感监测研究

利用2010年-2015年的卫星遥感监测数据进行土地利用分类解译,并结合地面调查统计资料,依据生态环境状况评价系统,对扬州市"十二五"期间的生态环境进行动态监测和评价.结果显示:在2010年-2015年期间,扬州市各区县市生态环境状况等级为"良",保持不变;"十二五"末与"十一五"末相比,扬州市所辖市区和高邮市生态环境状况略有变差,其它3个区县市则无明显变化;扬州市级生态环境状况略有变差,生态环境状况指数降低1.11;在扬州地区,生态环境质量的变化主要与植被覆盖程度和水的丰度变化有关.

Study onRemote Sensing Monitoring of Ecological Environment in Yangzhou City between 2010 and 2015

According to the ecological environment evaluation system, the ecological environment in Yangzhou city between 2010 and 2015 was monitored and evaluated based on remote sensing data from 2010 to 2015, combining ground survey and statis-tical data. During the 12th Five-year Plan Period, every district possesses"good quality" and the quality level of each district remains stable. Comparing data from the end of the 12th Five-year Plan and the 11th Five-year Period, the ecological quality of urban Yangzhou and Gaoyou districts were slightly dropped, causing the ecological environment variation level to be"fluctua-tion". The other three districts remained basically unchanged with the variation level as "stable". The ecological index of the whole Yangzhou city had decreased 1. 11, which indicated the ecological environment variation level to be"fluctuation". The var-iation of ecological environment in Yangzhou City was mainly related to the variation of vegetation coverage distribution and water abundance.
