河北省太行山区片麻岩类山地的地貌条件与林业利用

THE RELATIONSHIP BETWEEN THE GEOMORPHOLOGIC CONDITIONS AND THE UTILIZATION IN AFFORESTATION IN THESE GNEISS REGIONS OF TAIHANG MOUNTAINS, HEBEI PROVINCE

本文根据野外考察、试验观测和五十七种岩石风化物样品的化验分析资料研究了河北省太行山区片麻岩类山地的岩石类型、海拔高度、坡度、坡向、坡形和坡位等地貌因子与林业生产的关系,并探讨了本区常见树种对立地条件的要求,从而为该区坡地的科学利用和不同地貌条件下造林树种的优先选择提供了理论依据。

By investigation and observation in the field and analysis of samples of more than fifty kinds of rock, the relations between geomorphologic elements, types of rock, elevation, characters of slope (such as direction, angle and shape etc.)and the production of forestry in these gneiss regions of Taihang Mountains, Hebei Province, are studied. In addition, the environment conditions needed by common species of trees in these regions are discussed. Therefore a scientific basis for the utilization of sloping fields and the precedent choice of species of trees in afforestation under various geomorphologic conditions in these regions are provided in this paper.
