摘　　要：为了研究野生红树莓在河北省内的资源现状,掌握其在不同区域内的分布特征并探讨其表型性状对非生物生态因子的响应规律,该研究通过实地调查、典型植株取样,记录了野生红树莓在不同区域的生境条件和植株差异,并结合其表型性状指标与非生物生态因子进行分析。研究结果显示:野生红树莓在冀东区、冀北区、冀西北区和冀西太行山区均有不同程度的群落分布,介于海拔116~1767m之间。其适生土壤质地多为砂质壤土,且在砾石质量含量百分率44.44%以下、pH 5.33~7.61之间的土壤中均可正常生长。不同区域的野生红树莓具有相似的生境和植物群落,而分布类型存在差异;野生红树莓的叶形存在种质差异,主要分为掌状单叶和三出复叶两种类型。经相关性分析发现,非生物生态因子中的年积温和海拔对野生红树莓的表型性状起到了显著或极显著的调控作用。To study the current resource status of wild red raspberries in Hebei Province,to grasp their distribution characteristics in different regions and to explore the response of its phenotypic traits to abiotic ecological factors,this experiment used wild red raspberries in Hebei Province as research object.The habitat conditions and plant differences in different regions were recorded through field surveys and typical plant sampling.The phenotypic traits and abiotic ecological factors were analyzed.The study results showed that wild red raspberries had different degrees of community distribution in Eastem Hebei,Northwest Hebei,and West Hebei Taihang Mountains,ranging from 116~1767 m above sea level.Its suitable soil texture is primarily sandy loam,and it can grow normally in soils with a gravel percentage of less than 44.44%and pH 5.33~7.61.Wild red raspberries in different regions have similar habitats and plant communities,but the distribution types differ;the leaf shapes of wild red raspberries differ in species,mainly divided into two kinds of palmately simple leaves and ternate compound leaves.The correlation analysis revealed that the annual temperature and altitude among the abiotic ecological factors significantly regulated the phenotypic traits of wild red raspberries(P<0.01).
