伏牛山植被及土壤养分分布特征研究

Study on the Distribution Characteristics of Vegetation and Soil Nutrients in Funiu Mountain

[目的]研究伏牛山地区植被群落特征和不同植被带土壤养分分异规律。[方法]采用群落生态学的调查方法,分析了伏牛山南北两坡植物种类分布特征、植物种的地理分布特征以及海拔梯度上的植被垂直带谱。采用常规养分分析法,测定了不同植被带的土壤养分含量。[结果]伏牛山现有微管植物175科、892属、2 879种,其中,中国特有种1 400种、热带分布种388种、温带分布种601种;由于伏牛山南北两坡植被分布的不同,导致相应植被带的土壤养分存在明显分异。[结论]该研究对了解伏牛山地区植被与土壤的生态过程具有指导意义。

[Objective] The research aimed to study the vegetation community characteristics and the soil nutrient difference laws of different vegetation zones in Funiu Mountain.[Method] Using the investigation method of community ecology,the distribution characteristics and geographic distribution characteristics of plant species,the vegetation altitudinal zonation at the altitude gradients on the south and north slopes of Funiu Mountain were analyzed.The content of soil nutrients in different vegetation zones was measured by using the routine nutrient analysis method.[Result] The vascular plants were recorded 2 879 species and affiliated to 175 families,892 genera.Among the whole species,there were 1 400 Chinese endemic species,388 tropical species,and 601 temperate species.Different vegetation distributions in the south and north slopes of Funiu Mountain led to the obvious difference of soil nutrients in the corresponding vegetation zones.[Conclusion] It is conducive to understand the ecological process of vegetation and soil in Funiu Mountain.
