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.
