摘 要：
Using drought degree evaluation of different types of steppe regions in Inner Mongolia, according to the country standard of Arid Disaster Grade in The Northern Grassland of China, a series of functions those comprised scattered data interpolation and isopleth analysis, complicated region resolution, surface area calculation, drawing distribution map of drought degree and the drought degree area statistics of different steppe regions were achieved through the programming, in order to improve the level of quantitative evaluation of steppe drought and the ability of high-efficiency operational applications. The computational method met the demand of the specific operational applications that the drought occurrence degrees of different types of steppe area were analyzed and evaluated objectively. This article for reference was supplied to the interrelated operational works.
