Abstract

Abstract:

Steppe is a key part of the ecological environment construction in the west region, and its ecosystem is very fragile. In recent years, desert steppe drought disasters occur frequently. Taking the Yinshanbeilu National Field Research Station of Desert Steppe Eco-Hydrological System in Inner Mongolia as the experimental area, the precipitation changes at different slope positions are monitored, the relationship and function between meteorological factors and drought index PA value are analyzed, and a regression model is constructed. The results show that: (1) the precipitation at different slope positions of the desert steppe at the north foot of Yinshan Mountain is: downhill>middle slope>uphill, and the corresponding drought index PA value is: uphill_PA > middle slope_PA>downhill_PA (2) From the observation of each time scale, monthly scale analysis shows that there are different degrees of drought at each slope position, and the drought frequency is high; Seasonal scale analysis shows that light drought occurred only in winter; The annual scale analysis found that the region did not reach the drought threshold in recent 5 years. Overall, the average annual precipitation in this area is sufficient and there is no drought disaster. (3) The multiple regression model constructed according to the main meteorological factors such as precipitation, air temperature and wind speed and the drought index PA value is: Y_PA=78.799+0.255x₁-3.395x₂-1.831x₃, R²=0.994, the fitting degree of the model is high, which can better reflect the drought situation in the region. It provides a theoretical basis for further studying the relationship between multi meteorological factors and various drought indicators, as well as constructing drought evaluation system.

Key words: precipitation, drought index, desert steppe, the northern foot of Yinshan Mountain, multiple linear regression
