45 samples collected in the Qing Tsubosato 14c's determination of the experimental analysis of particle size and indicators of environmental magnetic record of past environmental changes in the sediment extract the Panzhihua areas clear Tsubosato profile.

In the ping of the township acquired the 45 samples, 14 C s determination, grit and environmental magnetism of the lab analysis indicators, extract Panzhihua area seems clear rural profile in the sediment record of past environmental change.

Through to 45 samples which gathers in the clear level ground township, carries on the 14C age the determination, the granularity and the environment magnetism target experimental analysis, the past environmental variation information which in the extraction kapok area clear level ground township se

By Qing ping 45 samples collected by the Heung Yee Kuk, 14C, particle size, and for the determination of indicators of environmental magnetism: an experimental analysis, extraction of Qing ping profile sediments in panzhihua area record of past environmental changes in information.
