Abstract:

In order to study climate change in temperate grassland and its impact on nature-social-economic systems and its response and adaptability, this paper reviewed the changes of drought and the main elements, such as temperature, precipitation in temperate grassland, and regional climate changes forecasting research. Then, the paper summed up the latest research about the impacts of climate change on temperate grassland vegetation. The study found that climate showed significantly higher temperature, more significant regional differences in precipitation, drought increasing, and the vegetation phenology, physical characteristics, productivity, NDVI changed significantly. However, there still existed much uncertainty in climate change forecast and its scale. Therefore, it was urgent to carry out research on climate change and its heterogeneity at large spatial-temporal scale. Besides, it also needed to further strengthen the impact of climate change and adaptation.
