要:通过本研究发现,蒙古国典型草原游牧区的夏营盘和冬营盘的土壤物理及养分性状总体上都优于内蒙古典型草原轮牧区的夏营盘、冬营盘及定居放牧区;而且在内蒙古典型草原轮牧区的土壤性状也优于定居放牧区。三个放牧区中定居放牧区的退化最为严重,轮牧区次之,游牧区主要因气候干旱,少雨等原因出现退化现象,但退化速度和程度低于内蒙古同类地区(轮牧区和定居放牧区)。过度放牧等人类活动的影响是轮牧和定居放牧区的草地生态环境退化的重要原因。 关键词:不同利用方式 土壤理化性质
植被群落特性 Study on Soil and Vegetation Characteristics under Different Grazing of Mongolian Plateau — Investigation Report of Desertification in Typical Steppe between China and Mongolia Bao xiang1, Awadorji2,Chunlan1,Baolidao1, Zhaolejirigala3,Aogenqiqige3 ,Budebatar3,Sanasiqin1 1 Inner Mongolia Agriculture University;2 Institute of Animal Husbandry in Mongolia;3 ”Green gold project” in Mongolia, Ulaanbaatar Abstract: Result showed that soil physics and chemical characteristics under the nomadic grazing in summer and winter camp of Mongolia are higher than rotational grazing, settled grazing in Inner Mongolia. Soil characteristics under the rotational grazing is higher than settled grazing in Inner Mongolia. Grassland is seriously degeneration in the settled grazing, degradation under the rotational grazing in Inner Mongolia is lower than Mongolia. Grassland is expressed degeneration situation under the nomadic grazing, it mainly related to climate’s changes, precipitation in Mongolia, but degeneration speed and degree are lower than Inner Mongolia. Grazing and people’s activity lead to grassland degeneration.
