| 摘 要： | The investigation was carried out on 10-year-old plantation of Fraxinus mandshurica in Mao‘er Mountain Experimental Station of Northeast Forest University.tree height(H),diameter at breast height(D1.3) and the increment of tree height in 5 years (H5),the thickness of humus layer,as well as the soil moisture were measured for the plantation and the growth indexes(H,D1.3,H5) for different site conditions were analyzed.The results showedthat main site factors influencing the growth of Fraxinus mandshurica were soil moisture,gradient and location of siope in order.The growth of Fraxinus mandshurica was better on the middle-or up-slope site than on the down-slope site.Soil moisture and late frost caused by terrain are the main reasons that limit the growth of Fraxinus mandshurica plantation.

| Abstract: | The investigation was carried out on 10-year-old plantation ofFraxinus mandshurica in Maoler Mountain Experimental Station of Northeast Forest University. Tree height (H), diameter at breast height (D13) and the increment of tree height in 5 years (H5), the thickness of humus layer, as well as the soil moisture were measured for the plantation and the growth indexes (H,
D1.3, H5) for different site conditions were analyzed. The results showed that main site factors influencing the growth ofFraxinus mandshurica were soil moisture, gradient and location of slope in order. The growth ofFraxinus mandshurica was better on the middle-or up-slope site than on the down-slope site. Soil moisture and late frost caused by terrain are
the main reasons that limit the growth ofFraxinus mandshurica plantation.
