| Abstract: | Ejina Oasis is located in a typical arid region.Based on observational data of soil moisture and environmental factors,this article studied the spatio-temporal characteristics of soil moister of different vegetation cover types in Ejina Oasis,analyzed the relationship between soil moisture and environmental factors,and then established regression functions of soil moisture and environmental factors.The results are as follows.Soil types and soil structure are quite different in different environments,and the... |
