落叶松人工林生态场中单株营养效力的分布

The Distribution of the Single Tree Nutrient Efficacyin Ecological Field of the Larch Artificial Forest

通过落叶松人工林单株土壤中营养元素分布的测定，指出了落叶松人工林生态场中，影响干涉势的营养效力因子的作用，同时发现这种分布与地下生物量的分布是一致的。

The singal tree nutrient efficacy elements had be determined in the soil of Larch artificial forest Inthe ecological field of Larch artificral forest. We pointed out the effects of nutriene efficacy elements for effect-ing interference pertential and samtime,we also finded that the distibotion and the distribution of the bianassunder ground showed no difference
