摘要:

在帽儿山地区对不同立地条件下水曲柳人工幼林生长指标进行标准地调查,并运用数量化方法研究了影响水曲柳人工林生长的立地因子。结果表明:影响水曲柳人工林生长的主要立地因子依次为坡位、土壤A层厚、坡向和坡度,其中坡位为主导因子。水曲柳人工林在中上坡位生长最好,在下坡位生长差。根据立地因子划分了34个立地类型。此外对不同立地类型的养分状况进行了分析,发现养分并不是限制水曲柳生长的主要因子。

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
