Temporal and Spatial Variation in Vegetation Coverage and Its Response to Climatic Change in Marshes of Sanjiang Plain, China

Sanjiang Plain is the most extensive marsh distribution region in China. Marshes this can protect biodiversity, regulate climate, and provide habitats for wild animals plants. The normalized difference vegetation index (NDVI) a crucial indicator of coverage, which may reflect ecosystem structure functional features. Clarifying spatiotemporal change coverage its climatic drivers vital observing predicting Plain. Using meteorological dataand MODIS NDVI data from 2000 to 2020, we analyzed variation effects We found that growing season increased significantly at rate 0.011/decade, indicating growth has obviously improved during past 21 years. Furthermore, increase minimum (Tmin) maximum (Tmax) temperature July promote plant growth, increasing nighttime Tmin stronger impact on promoting than daytime Tmax month. In addition, August whereas precipitation was unfavorable
