| Abstract: | The paper measures and analyses growth courses biomass dynamics for natural grass-es. The authors select Glycyrrhiza uralensis、stipa breviflora Aneurolepidium dasystachyssophora alopecuroides、Artermisia ordosica and lespedeza davurica as the obiects of studyThe paper uses a single-variable regression method to analyse the relations between thegrasses biomass and precipitatiOn temperature humidity and sunshine hours,and found lin-ear equations respectively.In the mean time,the authors also analyse the multi-variablerelation between the grasses biomass and the precipitation, temperature, soil moisture con-tent relative humidity and the sunshine hours. The relations satisties the regression equa-tion y_2=b_0+b_1x_1+b_2x_2+b_3x_3+b_4x_4+b_5x_5. From the analysis,the paper concludes that theenvironmental factors,influences on grass biomass follows as:Soil moisture content>tem-perature>precipitation>relative humidity>sunshine hours. |
