中文摘要	宁夏银川水洞沟遗址2号点剖面孢粉分析结果表明:该地区在晚更新世晚期孢粉组合以草本植物花粉占绝对优势,有Chenopodiaceae、Artemisia、Zygophyllum、Ranunculaceae和少量的Euonymus、Ephedra和Ni-traria等,木本植物花粉次之,有Pinus、Picea、Abies、Betula和Ulmus等,蕨类植物孢子较少,有Lycopodium、Selaginella和Adiantum等。根据孢粉含量的变化,可划分出4个孢粉带:Ⅰ带(72-38ka BP)孢粉浓度较高,反映区域植被属于生长有少量灌木的以Chenopodiaceae和Artemisia为主的温带草原环境,局部地区生长有比较茂盛的水生或湿生植物,为湿地环境;Ⅱ带(38-29ka BP)孢粉浓度较低,草本植物花粉占有绝对优势,反映生长有少量阔叶树的以Compositae为主的温带草原环境,较多水生及湿生植物的出现说明附近有湿地分布;Ⅲ带(29-20ka BP)孢粉浓度极低,表明该地区总体特征为生长有零星Betula、Ulmus的温带荒漠草原环境,附近生长有水生或湿生植物,周边山地上生长有少量Picea和Abies;Ⅳ带(20-18ka BP),孢粉浓度极低,反映区域植被面貌属于生长有零星Betula、Ulmus的温带荒漠草原环境,山地上生长有较多的Picea和Abies。
英文摘要	27 sporopollen samples were obtained and analyzed from Shuidonggou locality 2 in Yinchuan,Ningxia.The statistic results show that herb pollens took absolutely advantage,including Chenopodiaceae,Artemisia,Zygophyllum,Ranunculaceae and a small amount of Euonymus,Ephedra,Nitraria and so on.Woody plant pollens stood in a secondary position,including Pinus,Picea,Abies,Betula and Ulmus etc.Fern spores were few,contained Lycopodium,Selaginella,Adiantum and so on.According to sporopollen assemblages,it can be divided into four strips.In the first strip(72-38 ka BP),the sporopollen content was high,water grown and hygric vegetable was prosperous,it belonged to temperate grassland zone with some marshes and relatively warm and humid climate.In the second strip(38-29 ka BP),the sporopollen content was low,herb pollen occupied absolutely advantage in this site.In the other hand,some deciduous broad-leaved trees such as Quercus and Ulmus grew with the coming ferns and Urtica.It belonged to temperate grassland zone mainly with Compositae and a small mount of broadleaf.Aquatic and hygric plants grew flourishing in part of the region which was a marsh environment.In the third strip(29-20 ka BP),the sporopollen content was very low.It should be a temperate desert steppe environment with some Betula,Ulmus.Aquatic and hygric plant grew flourishing in part of the region,marsh condition,a small amount of Picea and Abies trees grew surrounding hills.In the forth strip(20-18 ka BP),the sporopollen content was extremely low.It showed a temperate desert steppe environment with some Betula and Ulmus.A lot of Picea and Abies trees grew on hills.
