四川绵竹立地分类及立地质量评价研究

Site Classification and Site Quality Evaluation of Dendrocalamus farinosus in Sichuan

  • 摘要: 绵竹是四川重要的造林竹种。本研究对四川省绵竹的生长情况进行全面调查,在此基础上开展绵竹立地分类和立地质量评价。研究共划分了1个立地区域,两个立地区,4个立地亚区,共计45个立地类型。立地质量评价结果表明:海拔、土壤厚度、坡位、坡度是影响绵竹生长的主要因子。在绵竹造林时,应考虑选择厚层土壤(>60 cm)、中低海拔(800 m以下)、坡位中下和坡度<25°的立地条件。

     

    Abstract: Dendrocalamus farinosus is one of most important bamboos in Sichuan.In this study,an experiement on site classification and site quality evaluation of Dendrocalamus farinosus was conducted by use of the comprehensive survey.One site area,two site regions,four site sub-regions and forty-five site types were divided in the study.The result of site evaluation showed that altitude,soil thickness,slope position and slope gradient were main in fluential factors on the bamboo growth.It was also found that there was no obvious correlation between slope aspect and bamboo growth.As a consequence,a conclusion could be drawn that deep soil (>60cm),middle-low altitude(<800m),middle-low slope position and gentle slope gradient(<25°)should be considered before forestation of this bamboo species.
