摘要

对全新世古水土流失与古人类活动相互影响的研究方法进行了讨论和实践。借鉴第四纪环境学的研究手段

利用古人类活动区域周围的河流、湖泊沉积物及坡脚堆积物

可以获得古水土流失的信息:在一定条件下

沉积物中孢粉数量的减少或草本植被的相对增加、磁化率的增大、迁移能力较弱的元素及化合物在沉积物中的富集

或沉积物分选差、粒度增大等

都可能指示着古水土流失的发生。通过对辽西大凌河剖面的孢粉分析

指出红山文化遗址堆积较薄且分布稀疏

可能与古水土流失加剧有关。

Abstract

The method of stud乒ng for interaction between the past man activities and soil and water loss appearing in Holocene is discussed and practiced. The information of the past soil and water loss could be gott-en from the sediment of aver

lake or the bottom of slope according to the measure methods that used in Quaternary. In some degree

that the number of pollen is decr-easing or vanished

the susceptibility is increasing，the elements or compounds transferring difficulty accumulate

or granularity is increasing in the sediment

may suggest that the soil and water loss occurr

d in the past time.The archaeolog-ical site of Hong shan culture is abroad but sparse

and the deposit of culture layer is thin that may be caused by the past soil and water loss during that time in terns of pollen analysis in the sediment of Doling aver in the north of Liaoning province.
