摘要
以戴云山黄山松群落为研究对象,采用样方法在1100~1800 m海拔设置31个黄山松群落样地,分析海拔梯度下黄山松群落特征及土壤养分状况.结果表明:海拔越高黄山松群落的多样性越低;黄山松种群呈现聚集分布;土壤有机质、全氮含量随海拔升高呈先升高后降低的趋势,而土壤全钾的含量呈先下降后升高的趋势.海拔是影响黄山松群落分布的主要因子,且较高海拔地区的土壤有机质、全氮和全磷含量低于较低海拔地区.黄山松群落林下土壤全磷含量均低于0.5 g·kg^(-1),呈现磷限制.
In order to explore the dynamics of Pinus taiwanensis community and soil nutrition in Daiyun Mountain,31 typical sample plots along altitudinal gradient(1100-1800 m)were investigated for the community compositional and spatial characteristics and understory soil nutrients.The results showed that the P.taiwanensis communities in Daiyun Mountain exhibited an aggregated distribution pattern with decreased diversity along the altitudinal gradient.The soil organic matter(SOM)and total nitrogen(TN)in the P.taiwanensis communities trended to increase first and then decrease with the altitudinal gradient,whereas the opposite trend was observed for total potassium(TK).Altitude was the primary factor affecting the distribution of P.taiwanensis communities.Soil nutrient pool,mainly concerning SOM,TN and total phosphorus(TP)was lower in the higher altitudes,with TP content less than 0.5 gkg^(-1),soils under the P.taiwanensis plantations were under P shortage.
