山东山旺中新世植物群研究进展

ADVANCES OF RESEARCH ON MIOCENE FLORA FROM SHANWANG IN SHAN DONG PROVINCE

山旺盆地位于东经１１８°Ｅ，北纬３６°Ｎ，是一个中新世中期内陆湖泊沉积盆地。地层内保存了丰富的植物及动物化石。自４０年代至今，已对山旺中新世植物群中的大植物化石（８７属１２５种），植物孢粉（４１属７１种），硅藻（１６属４５种）及真菌（９属１５种）进行了详细的研究。考虑到山旺中新世植物群处于全球气候变化的转折期，对其进行埋藏学，古环境重建等深入细致的研究，对阐明全球中新世气候变化的机制具有重要意义。

The Shanwang Basin is located at 36°N,118°E,and is an interior lake basin of middle Miocene age which contains abundant plant and animal fossils. Many researches on plant megafossils,spores and pollen,fungi and diatoms have been done since 1940's. Since Shanwang Miocene Flora covers a critical time period for global climate change,further work about its topography,palaeoecology and palaeoenvironments will be very important in explaining the cause of Miocene climate change.
