摘　　要：应用光学显微镜和扫描电子显微镜对皖南山区肖坑林场10月开花的26科41属42种2变种的花粉形态特征进行了观察和描述。44种植物包含草本植物38种、木本植物6种,其中菊科(Compositae)植物有11种。花粉类型以萌发孔为3孔沟为主,占52.3%;还包含单沟、3沟、多沟、散沟、3孔和多孔等类型。外壁纹饰以细网状和具刺(包括刺状、微刺状、条纹-微刺状、微刺-穿孔状、长刺状和刺突状)为主,分别占27.3%和47.7%;还有粗网状、颗粒状、棒状和条纹状纹饰等。对这些种类花粉形态特征的观察和描述可为第四纪地层花粉研究提供基础资料,也可作为中低山暖湿气候环境的代用指标。Pollen morphological characteristics of 42 species and 2 varieties （flowering in October） of 41 genera belonging to 26 families from Xiaokeng Forest Farm in the mountain areas of South Anhui were observed and described by light microscope （LM） and scanning electron microscope （SEM）. The 44 plants contain 38 herbs and 6 woody plants, in which 11 plants belong to Compositae. Pollen types are mainly 3-colporate apertures with a percentage of 52.3%, and also contain monocolpate, 3-colpate, stephanocolpate, pantocolpate, 3-porate and stephanoporate types. Exine ornamentations of pollens are mainly fine reticulate and acanaceous （including spinulose, microspinulose, striate-microspinulose, microspinulose-perforate, longue-spinulose and spike-like） with the percentages of 27.3% and 47.7% , respectively. Moreover, there are other exine ornamentations, such as rough-reticulate, granular, rod- like and striate. Observation and description on pollen morphological characteristics of these species could provide some basic data for pollen researches of the Quaternary Strata, and could also be used as substitutive indexes for low mountain warm-humid climate.
