摘要
[目的]研究五大连池地区矮曲林的物种多样性特征,分析土壤因子与不同类型矮曲林分布的关系,为五大连池矮曲林深入研究和保护提供理论依据.[方法]采用样方调查法,调查矮曲林物种多样性,同时取土壤样品测定各项指标.[结果]五大连池地区3种矮曲林的物种多样性指数较低;3种矮曲林的土壤磷和钾的含量都较高;矮曲林物种多样性指数与土壤有效磷、全氮、全钾含量有相关性,与其余指标相关性不大.[结论]五大连池地区矮曲林物种多样性和丰富度整体较低;矮曲林物种多样性指数只与土壤有效磷、全氮、全钾含量有相关性.
Abstract
[Objective] The aim was to study the characteristics of elfin forest species diversity in Wudalianchi,analyze the relationship between soil factors and different types of elfin forest distribution,provide evidence for in-depth studying and protected Wudalianchi elfin forest.[Method] The study used quadrat survey method to research the elfin forest species diversity,and took soil samples to determine the indicators.[Result] There were lower diversity index of three elfin forest species and higher content ofphosphorus and potassium in soil;the diversity index of elfin forest species had correlation with available phosphorus,total nitrogen and total potassium in soil but less correlation with other indicators.[Conclusion] There is low value of diversity and richness of elfin forest species in Wudalianchi area;the diversity index of elfin forest soecies has only correlation with available phosphorus,total nitrogen and total potassium in soil.
