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;水曲柳最适生的立地为山地中上腹,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。
The results showed that the main site factors influencing the growth of Fraxinus mandshurica plantations were soil moisture, slope and slope position, and the optimum manure The site for the mountain in the upper abdomen, and not suitable for gentle slopes in the lower abdomen. It is considered that soil moisture and temperature inversion due to topographical reasons are the main reasons that restrict the growth of Fraxinus mandshurica plantation.
