阿尔金山自然保护区的土壤类型及分布规律

The Soil Types in Arjin Nature Reserve

阿尔金山自然保护区在新疆若羌县东南部,东为青海,南为西藏,约在北纬36°00′—37°49′,东经87°25′—91°20′,总面积4.5万平方公里,平均海拔高度4500米。由于海拔高而交通困难,人迹难至,五十年代末科学院综合考察队土壤组,也仅到保护区北部阿尔金山分水岭一带。这里是高寒荒漠土和高寒草原土为主的土壤分布区。

The Arjin Nature Reserve, with the areas of 45, 000 square kilometers and the average elevation of about 4,500 meters,is located in 36°00'—37°49'N,87°25'—91°20'E of Ruoqiang County in Xinjiang. According to the comprehensive scientific expedition on the Nature Reserve in 1984, the article made a study on the soil forming factors, the characteristics of Parent material, the soil types and the mountain vertical soil zone, and divided the region's soil into 11 great groups and 25 subgroups, and drew a soil map of the Nature Reserve. Meanwhile, the article made a exposition of distributed regulation of seven vertical soil zone of soil and mountainous region in the main basins of the area. In the research, a 150 kilometers alpine medow soil zone was found for first time.
