摘要
采用标准地调查法测定朝鲜崖柏的土壤特征、林下植被和高生长规律.结果表明:朝鲜崖柏生长于土层较薄且呈弱酸性的山地暗棕壤,不同标准地林下植被差异明显;不同标准地朝鲜崖柏树高的年生长量均呈逐年下降趋势.
To evaluate the soil properties, understorey and height growth rhythm of Thuja koraiensis by using standard survey method. Thuja koraiensis saplings were generated from dark brown forest soil which was thin and slightly acidic. There were significant variations about understorey in different sample plots. Growth data revealed that the annual height growth of trees showed a trend of decreasing year by year.
