在东北林业大学帽儿山试验林场尖砬沟森林定位研究站(127(30'-127(34'E, 45(21'-45(25'N), 建立了水曲柳人工林.在对不同立地条件下10年生水曲柳人工林生长指标进行标准地调查,分析结果表明:影响水曲柳人工林生长的主要立地因子依次为:土壤湿度、坡度和坡位:水曲柳最适生长的地点为山地中上腹,而不适于坡度平缓的山地中下腹.认为土壤湿度和因地形原因引起的逆温是限制水曲柳人工林生长的主要原因.图3表6参6.

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 showed that main site factors influencing the growth of Fraxinus mandshurica were soil moisture, gradient and location of slope 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.
