中文摘要：

通过对清水江文书中典型契约文书的梳理，对清代贵州苗族侗族地区货币流通中的银两成色、平砝标准和银钱比价关系等问题进行了初步考证。清代贵州苗侗地区的货币流通经历了从规范到失序，然后又趋于规范的过程。清代中期银两成色与平砝标准的混乱，以及银价的剧烈上涨扰乱了木材市场与土地市场秩序，加剧了苗侗社会矛盾。

Based on the finishing of the Qingshuijiang documents, the preliminary verification of the color of silver coins, the light weight standard and therelationship between the monetary prices have been done in curren-cy circulation in the Miao and Dong areas in the Qing Dynasty. The currency circulation of the Miao and Dong regions in Guizhou in the Qing Dynasty experienced the process from the ordered to the disordered situation. Af-ter that, it turned to be standardized again. In the middle of the Qing Dynasty, the chaos of silver tael color,light weight standard, and quick rise of silver pricesdisturbed the order of the timber and land market, and exacerba-ted local contradictions in the Miao and Dong society at that time.
