辽西北干旱风沙区杨树沙棘混交林气候生态效应和混交数学模型

The climatic--ecological effect of poplar--seabuckthorn mixed forest in the arid, windy and sandy district of north--western Liaoning and the mathematical model for mixing

本文对杨树、沙棘混交林气候生态效应进行了系统分析,探讨了沙棘对杨树影响的最大有效距离;建立了杨树、沙棘混交林互助互促群落的数学模型,并提出了初育杨树林2m×3m密度行间套栽沙棘的理想设计。

In this treatise, the climatic-ecological effect of poplar- seabuckthorn mixed forest is systematicaly analysed. The seabuck- thorn can effectively influence the growth of poplar tree; and the mathematical model of the mutual-aiding community of the mixed forest is established. The initial density of 2×3m between poplar trees with the seabuckthorm planted between the rows is considered ideal.
