海岱地区新石器时代考古学文化序列已经基本建立,重建该地区新石器时代气候与环境演化过程,是深入理解人类文化发展背景和人类与环境关系的重要前提。现有的考古学和古环境科学研究成果显示,距今7000—6000年前后,山东西南部的汶泗流域生长着现今生活在长江流域的扬子鳄;距今5000—4000年前后,山东东南部的日照一带生长着刚竹,而现代的刚竹自然生长区域是在江淮之间;辽东半岛和华北平原第四纪沉积物中的孢粉等记录了全新世早期的温暖湿润气候和全新世中期气候逐渐冷干的变化过程。这些研究成果说明,在整个新石器时代海岱地区的气候都比现在温暖湿润,相当于现代的江淮地区。目前关于该地区古气候和古环境的研究,取得的认识远少于存在的问题,主要表现在:(1)研究成果的时间和空间分辨率低;(2)年代学问题需要深入研究;(3)海岸线变迁问题有待深入;(4)对人类活动影响环境的问题关注不够。
The basic chronology of the Neolithic Age in Haidai Region has been established. It is an important condition for deeply understanding the background of cultural development to reconstruct the climate and environment evolution during the Neolithic Age in this region. The present archaeological and environmental data indicate that, during the Neolithic Age, it was as warm and humid as it is in the present Jiang-Huai region.The Yangtze alligators lived in the Wensi drainage area of southwestern Shandong which are currently living in the Yangtze drainage area. During about 5000-4000 a BP ,phyloschatis viridis lived in Rizhao of southeastern Shandong, while currently they are living in the Jiang-Huai drainage area. The sporopollen in the Quaternary sediments from the Liaodong Peninsula and North China plain indicates a warm and humid climate in the Early Hollocene and a gradually colding and drying process in the Middle Hollocene. These data show that during the whole Neolithic Age, climate in the Haidai Region was warmer and more humid than today which is similar as the present Jiang-Huai area. However, there are more questions than understandings obtained about the ancient climate and environmant in the Haidai Region. The main questions are as following:(1)The low resolution of time-spatial distribution of the results;(2)More researches need to be carried out about the chronology;(3)Deep research about the sea level change needs to be done;(4)More attention should be paid to impact of human activities on the environmental change.
