英文摘要	Siziwang banner desert steppe is a typical arid inland region, which is also one of the most ecologically vulnerable regions in the Inner Mongolia plateau. In this article, the Siziwang banner is taken as a typical case, for studying the spatiotemporal dynamic of NPP in desert steppe based on the Carnegie-Ames-Stanford Approach (CASA) model from 2003 to 2017, and analyzing the response of grassland NPP to the change of key climate factor, including temperature and precipitation. The results indicate that, 1) in terms of time, the grassland NPP in Siziwang banner desert steppe decreases first and then rises, while in terms of space, it decreases from south to north. 2) the NPP is more sensitive to precipitation with average partial correlation coefficient of 64.74%, which is higher than that of temperature. 3) the average of lagged time for NPP responding to temperature is 1.78 months and the average of lagged time for NPP responding to precipitation is 3.17 months. Precipitation at the early stage of vegetation growing season is particularly important for the growth of grassland vegetation in desert steppe.
