摘　　要：本文应用数量化理论Ⅰ的方法对长白山北部山区和三江平原低平区内天然水曲柳进行了立地质量评价。结果表明:影响水曲柳生长的立地因子顺序是坡度、坡向、土壤A层厚、土壤总厚和坡位;最适于水曲柳生长的立地是缓的半阴半阳坡的下坡位,最不适于水曲柳生长的立地是陡的阳坡的上坡。并建立了一个立地因子与水曲柳平均优势高的预测方程。The site quality of the natural manchurian ash in the district in the northern part of the Changbai Mountains and the low and flat area of Sanjiang plain was evaluated by using statistic model. The results show that the main site factors affecting growth of the natural manchurian ash are slope degree, aspect, depth of soil layer A, total depth of the soil layer and position. The optimum site for the growth of manchurian ash is on the lower slope position with a gentle slope degree and the aspect of E, W, NW and SE. The poorest site is on upper slope position with a steep slope degree and the aspect of S and SW. A predictive statistic model of dominant height growth to site factors was developed in this paper.
