摘  要:
本文通过对23块样方690个样点资料的分析表明,海拔的变化对落叶松叶蜂种群密度、生态型有显著影响,这种影响按海拔变化可划分为三种生态类型,在每种生态型之中种群密度、分布型呈规律性变化。在此基础上建立了种群密度与海拔高度间的回归模型。

摘  要:
Describes the influence of elevation variation on the population density of larch sawfly and its ecological type based on an analyses of sample plot data. Accordingly, 3 ecological types are divided, and in each ecological type, the population density and spatical distribution varied regularly. A population density and elevation regression model is set up on this basis.
