摘    要:调查分析了海南岛各种热带植被下的表土花粉,并根据花粉数据进行植被类型的模拟。结果表明,表土花粉类型复杂,优势种不明显,反映了热带植被下的植物种类繁多复杂的特性。分模拟能够较好地反映热带气候下的雨林,季雨林和干草原植被,其地理位置与地区植被的地理分布基本一致,海南岛山地的花粉模拟还恢复了热带山地植被,而海岸红树林植被能够被海岸带的花粉证据所模拟。该研究能够为我国大范围表土花粉调查和热带植被类型提供花

Abstract:Surface soil pollen under various tropical vegetations in Hainan is investigated and these pollen data are used to do simulation of vegetation types.The simulation is based on functional plants,the climatic indexes of which are determined by coldest monthly temperature and relative humidness.According to this,the known phytogeographic and phytoclimatic characteristics can be used to combine different functional plants into vegetations,namely,equatorial rain forest,tropical littoral mangrove,tropical lalang grass,tropical mountain monsoon rain forest,tropical monsoon forest and subtropical aiphyllium.The simulation results show that equatorial rain forests were distributed around 3 pollen sites in the south of the Hainan Island,and 10 pollen sites in the north of the island are simulated to be in tropical monsoon forest environment,2 pollen sites in the central part in mountain monsoon rain forest and subtropical aiphyllium environment,pollen sites around the Chunlan Bay and Sanya Bay in tropical littoral mangrove environment,and 2 pollen sites in the northwest in tropical lalang grass environment.Simulation of vegetation types in each pollen site is nearly in line with regional vegetation,indicating that pollens can reflect vegetation types in different tropical climates.
Keywords:surface  soil  pollen    tropical  vegetation    Hainan  Island
