摘  要：
This paper deals with the water regime of yellow-brown earths of various textures under Chinese fir (Cunninghamia lanceolata) stands and its growth. Experimental data for two years were treated with multivariate analysis methods. The curve of seasonal variation and the results of cluster analysis of moisture regime in soils with various textures showed that in spite of existence of six texture grades of the soils used in the experiment, there were only two types of soil water regime, i.e. the type of the soil with light texture and that of the soil with heavy texture. The results of correlation analysis showed that the seasonal variation of soil moisture of the light texture type was closely related with tree growth; on the contrary, that of the heavy texture type did not present such correlation with an exception of severe drought condition. The results of multiple regression analysis has demonstrated that in soils of light texture type, one can predict the soil water regime of a month after according to the data of precipitation and evaporation on hand; but this method can not be applied to the soils of heavy texture type. Besides, marked distinction was found between the data of soil moisture regime determined in situ and these obtained from soil column in laboratory investigation by precedent authors.
