| 摘要 | Based on the data of NDVI and meteorological factors in Siziwang Banner from 2000 to 2021, the temporal and spatial variation characteristics of NDVI in the grassland of Siziwang Banner and its responses to climate change were analyzed. The results show that the NDVI of grassland in Siziwang Banner tended to rise overall, with the average tendency rate of 0.05/10 a. The annual variation of NDVI was mainly driven by precipitation, and there was an extremely significant positive correlation between the two. During the growing season, temperature was positively correlated with NDVI in May, but then the correlation gradually turned negative. NDVI was generally positively correlated with precipitation, and there was a significant lag. |
