摘要

在调查北京八达岭林区刺槐(Robinia pseudoacacia)、侧柏(Platycladus orientalis)及其混交林生长量、土壤理化性质、水源涵养能力、病虫害的基础上

研究其结构与功能关系.结果表明

混交林比纯林具有更好的生长量

土壤理化性质得到进一步改善

从而提高水源涵养能力.另外

混交林还能够提高林分抵抗病虫害的能力.采用混交的方式为:1行刺槐3行侧柏循环混交

刺槐株数不超过1/4.本项研究以期对北京市森林健康经营具有一定的指导意义.

Abstract

The relations of configuration and function were studied by comparing growth mass

the quality of soil physics and chemistry

water conservation

plant diseases and insect pests for Robinia pseudoacacia

Platycladus orientalis and their mixed forest at Badaling forest centre in Beijing.The results showed that: the growth mass of mixed forests is higher than that of pure forests

the quality of soil physics and chemistry is be improved

which increases the capability of water conservation.In addition

the capability of resisting plant diseases and insect pests is advanced by mixed forests.The mode is that the Robinia pseudoacacia of one line mixes the Platycladus orientalis of three lines

and the amount of Robinia pseudoacacia does not exceed 1/4

which has definite significance for forestry health in Beijing.
