RESEARCHES ON RELATIONSHIP AMONG HOLOCENE VEGETATION,ENVIRONMENT EVOLUTION AND HUMAN ACTIVITIES IN SHANGHAI REGION

Wang Kaifa Zhang Yulan Feng Weiqing(Department of Marine Geology,Tongji University,Shanghai,200092,China)  
Located at the south of the Yangtze River Delta, Shanghai region is a low-lying landwith many lakes and marsh swamps. Its particular natural environment presents a spe-cial relationship between human and natural environment.Through analysis of humanactivities in three cultural stages and natural environment,we come to the conclusionthat:when paleoclimate turned temperate and dry,water area shrank and relief becamehigher,which was convenient for human activities and development of economy and cul-ture. On the contrary,when paleoclimate became warm and moist,this region was full oflakes and marsh swamps,which would affect and limit human activities of economy andculture. This reflects the peculiar relation between human activities and natural environ-ment during Neolithic age.
