太行山中南部造林树种适宜性评价研究

笔者对太行山中南部主要乔灌木树种的分布及适宜性进行了调查和统计分析。太行山中南部造林过程中不同海拔梯度阳坡、阴坡适宜的针叶树种、阔叶树种、灌木树种的生长适宜性呈现出:耐阴、耐寒、喜湿的树种分布在阴坡且垂直分布跨度大,多度值较高;耐旱、耐热、不耐涝的树种分布在阳坡且垂直分布跨度大,多度值较高的分布规律。并提出了1100 m,1 100 m~1 400 m,1 400 m~1 700 m,1 700 m 4个海拔梯度按阳坡、阴坡划分的8个立地类型适宜的乔灌木树种,为太行山中南部造林树种的选择提供参考依据。

Study on Adaptability Evaluation of Afforestation Tree Species in South Central Taihang Mountain

This paper invested the investigation and statistic analysis on distribution and adaptability of main tree and shrub species in south central Taihang Mountain .The results showed that during south central Taihang Mountain afforestation , different altitudes, the sunny, shady suitable conifer, hardwood, shrub species growing adaptability showed shade tolerant , hygrophilous tolerant , hardy trees distributed in shade slope and in a wider range and had higher distribution abundance value.drought tolerant, heat tolerant, no water logging trees distributed in sunny slope and often had a wider distribution of the distribution range and higher abundance values .Four altitude gradients 〈1 100 m ,1 100 m~1 400 m ,1 400 m~1 700 m,〉1 700 m and in shady , sunny slope , eight types of suitable tree and shrub species were proposed , it could provide some references for the south central Taihang Mountain species selection for afforestation .
