“This paper is around the monitoring of soil moisture and the scale effect of the relevant research issues in arid / semi-arid areas. First of all, the surface temperature and vegetation index are inversed quantitatively using remote sensing data, and according to the distribution of vegetation index – surface temperature feature space, the soil moisture index is extracted. Then the regional soil moisture spatial heterogeneity characteristics are analyzed by means of geostatistics. Moreover, the best spatial resolution is determined for the study of soil moisture in this area. The study adopted a more effective understanding of regional scale soil moisture conditions, with a certain degree of scientific significance and practical significance.”
