为了解云南剑川旧石器时代中晚期植被和气候变化特点以及当地环境与人类活动的关系，选取象鼻洞遗址各地层的13个土样进行孢粉分析。结果表明：该遗址堆积时期孢粉植物群以亚热带和温带成分为主，类型相对丰富，呈温暖期气候特征，但气候存在小的波动，呈现出早期温暖湿润、中期短暂干旱、晚期又逐渐暖湿的特点；木本植物花粉在孢粉总量中占绝对优势，说明当时人类活动对自然环境的影响不明显；可作为食物来源的植物很少，因此，当时居住在象鼻洞的人类主要食物应来源于捕捞或狩猎；对照邻近地区已有的研究成果，推测该遗址气候变化与季风活动有关。

Jianchuan is located in Hengduan Mountains with complex landforms and diverse natural landscapes.Xiangbidong site is the first paleolithic cave relic discovered in Jianchuan area of Yunnan.The unearthed items including many stonewares,animal teeth and bone fossils are from the middle-late Paleolithic period.Jianchuan is situated in the south temperate zone with variable vegetations mainly based on altitude,terrain and soil.Some common plant species are represented by Castanopsis delavayi,Cyclobalanopsis oxyodon,Pinus sp.,Tsuga sp.,Abies sp., etc. In order to understand the paleovegetation and paleoclimate changes and the relationship between environment and human activity,the palynological analysis was firstly used to measure the 1 3 paleosoil samples from different layers in Xiangbidong site of Jianchuan area, Yunnan.The Xiangbidong site was divided into seven layers from bottom to top according to the accumulation periods.The total thicknesses of the deposits from trench were 5 7 cm in the west cliff and 45 cm in the east. Laboratory preparation for the samples followed the standard preparation method.1 6 1 6 grains and 5 1 polymorphs were identified.Based on the changes of the main components in the palynological assemblages, Xiangbidong site was divided into four stages.In the first stage,Xiangbidong site was under warm and humid climate condition with abundant Nyssa sp.and Pinus sp.pollen grains.Then,a short dry period followed the first stage with distinct occurrence of Chenopodiaceae in the second stage.The warm and humid climate condition was resumed again in the third stage recognized by Nyssa sp.and Fagus sp., and became the maximum in the fourth stage recognized by Cyclobalanopsis sp.and Nyssa sp. Taking into account of high woody pollen content on the whole,the signal for human activities was still weak at that time.Meanwhile,because few plants could serve as food source,fishing and hunting are possible the human being’s main approach for living.Late Paleolithic and early Neolithic climate changes were frequent in the adjacent areas including Heqing Basin and Diancangshan area, so that the climate change in Xiangbidong site might be related with monsoon.
