赣西北石灰岩地区淡竹生长环境研究

Studies on the Growth Environment of Phyllostachysglauca McCl.in Limestone Areaof the Northwest Jiangxi

通过８０块标准地资料，对赣西北石灰岩地区淡竹生长的立地环境作了比较全面的研究。研究指出：淡竹是一个适应性较强的竹种，赣西北石灰岩地区淡竹的生长环境较差且变化复杂；立地因子对淡竹生长的综合影响非常显著；在众多的立地因子中，坡位、坡形、土层厚度、土壤通气状况、土壤中水解Ｎ和全Ｐ含量对淡竹生长的影响比较显著。

The growth environment of Ph. glauca McCl.in limestone area of the northwest Jiangxi was studied.The following conclusions were obtained:(1)Ph. glauca McCl.can grow in the baddish environment.(2)It is very obvious that Ph. glauca McCl.was influenced by the actors of site (particulariy position and form of hillside;soil thickness;soil porosity;effective nitrogen and total phosphorus).
