Linear Analysis of Reed Growth Parameters in Baiyangdian Lake

A field survey was conducted about the data of reed growth parameters in the Baiyangdian Lake of Hebei province,a correlation analysis had also conducted.The results showed that here were high level of positive correlations,between plant height and leaf fresh weight,plant height and stem fresh weight,plant diameter and leaf fresh weight,leaf fresh weight and stem fresh weight,respectively,and the remaining groups presented distinct level of positive correlation.The 4 groups of parameters with high level of positive correlation had a quantitative model analysis using a linear function,laid a foundation for the further research of the reed in this area.
