摘要：
The normalized difference vegetation indexes (NDVI) of the Nansi Lake wetland in Shandong province is are calculated on the basis of MSS, TM and ETM+ remote sensing data collected by the Landsat satellites. The characteristics of seasonal vegetation activity of the Nansi Lake during 1973-2011 were revealed. The seasonal variation characteristics of wetland vegetation in Nansi Lake are not identical in the last 40 years. The NDVI in spring (P=0.0216) first decreased and then increased; The NDVI in summer (P=0.0007) and winter (P=0.0189) present a significant decreasing trend. The variation of the NDVI in autumn is small.
