摘　　要：盘锦湿地是世界上保存比较完好的滨海湿地和亚洲第一大芦苇沼泽区,它对周边地区的气候调节、空气净化都起着举足轻重的作用。基于高分一号卫星遥感影像、MODIS影像和气象观测数据,监测评价盘锦湿地植被生态质量,分析盘锦地区植被覆盖度和植被NPP变化情况及其与气温、降水、日照三种气象要素变化的关系。结果表明,2020年盘锦植被长势较好,2000年以来大部份地区植被生态质量呈上升趋势,其生态质量变化与气象条件尤其是降水量有一定的关系。Wetland inPanjin city is a relatively well-preserved coastal wetland in the world and it is also the largest reed swamp area in Asia.It plays an important role in climate regulation and air purification in the surrounding area.Based on the remote sensing image of GF-1 satellite,MODIS image data and meteorological observation data,this study monitored and evaluated the ecological quality of wetland vegetation,analyzed the changes in vegetation coverage and vegetation NPP changes in Panjin.Their relationship with meteorological conditions about temperature,precipitation,and sunshine were performed.The results showed that the vegetation growthwas well in Panjin in 2020.The ecological quality of vegetation in most areas was turning fine from 2000.That changes had a certain relationship with meteorological conditions,especially precipitation.
