摘要: 利用全国620多个站的气象实测资料,研究了我国农牧交错带的气候特征、气候变化,重点分析了干旱对农牧交错带南北摆动的影响。研究表明:我国农牧交错带地形地貌复杂,气候多变,干旱与风沙是其主要自然灾害。气候持续变暖、变干,土地沙化严重,沙尘暴频发。因此,建议农牧交错带进一步加大退耕还林还草力度,加强生态环境保护和治理,以免农牧交错带因气候变化而不断向南侵蚀。

Abstract: A serious of meteorological data observed at more than 620 stations in China is used to analyze the climate characters and climate change of the agricultural and pasturing interlaced zone. The influence of aridity on the shifting between south and north of the interlaced zone is stressed. In the agricultural and pasturing interlaced zone of China there are characteristics of complicated landforms, changeful climate, aridization, land desertification and most sand storms. So it is urgent to further return crop plots into forestry and grassland, strengthen the eco-environment protection and management, and to avoid the southward invasion of the agricultural and pasturing interlaced zone.

Key words: agricultural and pasturing interlaced zone of China, shifting between south and north, climate evolution character
