内蒙古荒漠草原生态环境监测区土壤环境监测初报

An initial monitoring report on soil environment of ecological environment monitoring area in Inner Mongolia desert steppe

草原地区，降水的波动性对草本植物的生理机理、生态学机理、演替机理、生物量、载畜量、表层土壤养分含量等生态因子影响很大。本文分析报告了降水的波动性对荒漠草原生态环境监测区及代表类型区等表层土壤养分含量的影响。

The fluctuation of precipitation will greatly affect the physiological mechanism、ecological mechanism and evolution mechanism of herbs,it also affects the ecological elements such as biomass、carrying livestock capacity and nutriment content of surface soil,etc.The paper analyses and reports the fluctuation of precipitation affected the nutriment content of surface soil of the ecological environment monitoring area and the representative type area in the desert steppe.
