摘要

利用4ａ的观测、试验资料对太行山区片麻岩裸地区的适生树种选择和沟道治理等问题进行了研究。在3种片麻岩裸地中，以黑云角闪斜长片麻岩裸地立地条件最好，适宜发展高效经济林；花岗片麻岩裸地次之，适宜发展水保林；片麻状花岗正长岩裸地立地条件最差，不宜直接开发利用，应以封山育林为主，在裸地区的沟道治理中，不宜采用横向谷坊坝，以纵向“护坡堤”为宜。

Abstract

Based on the experimental data for 4 years

the harness and utilization of various exposed gneiss slope land are discussed

and the suitable kinds of trees and the gully reclamation in the area which exposed slope land of gneiss is distributed widely are also discussed. The results show: The condition which is suitable to the growth of trees on the exposed slope land of biotite-amphibole-plagioclase-gneiss is the best of all

so it is suitable to develop the economic trees. The condition of exposed slop land of granite-gneiss is better

it can be used for soil and water conservation trees.The conditions of exposed slope land of gneiss-syenite is the worst of all

it can not be utilized directly

and should be set apart mountains for afforestation. Besides

the effect of the protection dam along the both sides of gullies is better than the sand-control dam across gullies in the gully reclamation.
