一、前言最近,扁柏的栽植比重增大,特别是关西地方(京都、大阪地区)出现了在赤松枯损的迹地上即使不适宜的地方也有栽植扁柏的倾向,因而招致大面积造林的失败,引起了人们的关注。在林冠郁闭的扁柏纯林内,由于植被消失,地表有机物和土壤易受雨水冲刷而流失,造成林地恶化。预防扁柏林这一缺陷的措施之一,是考虑将其与赤松混交。由于混交林能更有效地利用光照、水分、养分,物质生产量比纯林大,而且在防止土壤、有机物流失等环保效能和木材生产效能上

I. Introduction Recently, the proportion of planted cypress trees has increased. In particular, the Kansai area (Kyoto and Osaka areas) has the tendency of planting cypress trees even in areas unfavorable to the damage of the red pine, resulting in the failure of large-scale afforestation , Has aroused people’s attention. In the canopy canopy cypress pure forest, the disappearance of vegetation, surface organic matter and soil erosion by rainfall erosion, resulting in deteriorating woodlands. One of the measures to prevent the flaw in Cheplin is to consider mixing it with Akamatsu. As the mixed forest can more effectively use light, water, nutrients, material production than the pure forest large, but also in preventing soil and organic matter loss and other environmental performance and timber production efficiency
