Abstract

Abstract

Study is conducted of effects of such climate factors as rainfall, temperature and 0-cm ground temperature as well as surface vegetation cover in relation to diverse land cover types and land use modes upon the frequency and intensity of sandstorms in the central part of Inner Mongolia Plateau. It can be assumed that there is no universal feature regarding effects of such climate factors as temperature, precipitation and vegetation cover except greater effect given by rainfall, the higher impact of vegetation is limited to agriculture-pasture transitional zones and pasture land in sub-meadows and sub-steppes in the grazing land. The anti-desertization for reducing the danger of sandstorm should be specific to regional condition and vegetation restoring is suggested as the focus in the transitional zone.
