【摘要】 通过对内蒙古中部不同地表覆盖类型和土地利用方式下降水、气温、0cm地温等气候因子和地表植被对沙尘暴频率和强度的影响分析,认为:气温、降水等气候因子与地表植被覆盖对沙尘暴频率和强度的影响不具有普遍性,降水影响相对明显,地表植被覆盖的影响仅在农牧交错区和牧区草甸草原亚区表现明显。通过防治荒漠化来减少沙尘暴的危害需要因地制宜,农牧交错区应该是植被恢复的重点区域。更多还原

【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.更多还原
