内蒙古锡林河流域不同生境中鼠类群落结构及现存量研究

本文研究了锡林河流域草原生态系统不同植被群落和生境中鼠类的生物量和营养物质现存量。结果表明,不同的生境中存在不同的鼠类群落结构。生活在最适栖息地的鼠类具有较高的生物量和营养水平。鼠类营养物质现存量反映出栖息地植物可利用物质的潜在基础。 该研究初步提供草原生态系统潜在营养物质的基础资料和格局。

A STUDY ON THE COMMUNITY STRUCTURE AND STANDING CROP OF SMALL RODENTS IN DIFFERENT BIOTOPE IN THE SILIN RIVER BASIN,INNER-MONGOLIA

This work was carried out in grassland ecosystem at Basin of SilinRiver, Inner-Mongolia, for understanding the community structure and standing crop of small rodent in different biotope.The results obtained show that the specific biotope usually get together with a specific dominant rodent,and the different rodent community structure occour in different biotop. Living in the preferable habitat the rodent population has higher nutrient level and biomass. The nutrient standing crop of small rodent community may be in response to the potential material foundation of the utility of the habitat's vegetation., This preliminary study provide the date and pattern of potential nutritional material foundation in the grassland ecosystem.
