若尔盖高原沼泽是我国最大的一片高寒地区的泥炭沼泽,通过四年来沼泽地排水和实施不同的改造措施,沼泽土壤性状、植物群落和产草量均发生不同程度的变化,为改造沼泽,扩大牧场提供一些有价值的数据。

The Ruoergai marsh is the largest peat moor of the plateau and frigid zone in China.It is disteibuted intensively over Ruoergai,Hongyuan and Aba counties,Sichuan province.The area of the peat moor is about 31.14% (1315280 acre) of the region’s total pasture area.Though the number of livestocks have increased 4.5 times since 1949,the development of the region’s animal husbandry is hindered obviously for the moor gathering water and parasites breeding.Therefore,certain representive the Longriba peat moor was selected as a study base that was transformed in 1980. This paper mainly approaches the effects and relations of some factors (physics,chemistry,biology et al.)to the moor transformation,and provides some useful experiment for improving and expending pasture.
