Abstract

In this research,the population distribution of Magnolia sinostellata was studied in Fengyuan Township,Liandu District,Lishui City,southern Zhejiang Province.Soil samples were collected to determine physicochemical properties,and the effects of soil properties on the distribution of Magnolia sinostellata were studied by grey correlation analysis.The results showed that Magnolia sinostellata was mainly distributed in public welfare forests,the germination ability was very strong,but most of the plants had a small number of sprouts per cluster.The mean habitat soil pH value was 4.96,the moisture content was very low,the organic matter was rich,and the available phosphorus was significantly insufficient.The upper vegetation wasn’t the only factor affecting soil property differences among populations.Correlation analysis showed that the distribution of Magnolia sinostellata was closely related to soil pH value,available phosphorus and rapidly available potassium.Among them,pH value had the highest correlation.The content of available phosphorus in the middle soil layer was the most correlated with the number of plants (clusters) of Magnolia sinostellata,and the pH value in the topsoil layer was the most correlated with the average number of sprouts per cluster.

Key words： Magnolia sinostellata; distribution; sprouts; habitat soil; grey correlation analysis
