以北京山区天然荆条灌丛为研究对象,选择坡度、坡向、坡位、海拔、土壤厚度、土壤质地、土壤类型、裸岩率作为立地因子,运用数量化理论I的方法研究不同立地因子对荆条灌丛生长的影响。结果表明:坡向、坡位、海拔、土壤厚度、土壤质地和裸岩率影响荆条灌丛的高生长;坡向、坡位、坡度、土壤质地和裸岩率影响荆条灌丛的径生长。这为北京山区退化植被的恢复提供了理论依据。
Taking natural Vitex negundo in Beijing mountainous area as research object, we selected slope, slope, slope position, elevation, soil thickness, soil texture, soil type and bare rock rate as the site factors and applied quantitative theory I to study the effects of different site factors Influence of the growth of Vitex negundo shrubs. The results showed that the slope growth, slope position, elevation, soil thickness, soil texture and bare rock rate affected the growth of Vitex negundo shrub. The slope growth, slope position, slope, soil texture and bare rock rate affected the diameter growth of Vitex negundo. This provides a theoretical basis for the restoration of degraded vegetation in mountainous areas of Beijing.
