Abstract:

The growth of young Fraxinus mandshurica plantation on various site conditions in Mao′ershan regions was investigated by temporary sample plot method.Site factors influencing the growth of young stand were analyzed by quantity theory I.The results indicated that the main site factors influencing the growth of young plantation of Fraxinus mandshurica were position on slope,depth of soil A layer,aspect of slope,and gradient of slope successively,smong which the position on slope was the key factor.Thirty-four site types were classified according to analysis of site factors.Besides,the nutrient status of various site conditions was analyzed.The results indicated that the nutrients were not the restricted factor.

Key words: Fraxinus mandshurica, Young plantation, Site condition, Correlation between site factors and production
