| 摘 要： | 在东北林业大学帽儿山实验林场，对１０年生的水曲柳叶松滞状混交林及纯林进行了调查。结果表明：水曲柳在混交林中表现出明显增产。高生长比纯林增加１２．１％￣２５．５％，胸径生长增加１２．７％￣３２．３％，落叶松在混交林中也表现出增产的趋势。高生长比纯林增加４．１％，胸径生长增加１２．５％，种间关系属双方有利。运用简单竞争指数对树种的竞争程度进行比较表明：在混交林中仅用地上部测树因子构造的简单竞争指数并不

| Abstract: | The stand characteristics of 10-year- old ash and larch pure and strip mixture stands were investigated. The result shows that the growth of ash was improved obviously in the mixed stand. by 12.1%~ 25.5% for tree height and 12.7%~32.3% for diameter of breast height. The growth of larch showed less increase in the mixed stand. 4.1% for tree height and 12.5% for diameter of breast height. The interspecific relationship benefits both tree species. A simplified competition index was engaged to compare the competition level. The comparison result indicates that the simplified competition index constucted by using the above-ground stand characteristics could hardly tell the comprehensive (above-and below-ground)inter- specific competition level. The index shows mainly the above-ground competition. |
