贡嘎山是我国西南横断山系的最高山脉,东濒大渡河,西临雅砻江,是长江上游这两条重要支流的水源涵养地。同时,它又是四川省西部康定、泸定、石棉等县经济活动的重要生产场地。因此,合理开发利用贡嘎山的土壤资源,既是生态平衡所必需,也是当地群众生产生活所提出的要求。要做到合理利用土壤资源,了解土壤的生态功能是基本条件之一。在山区,土壤生态功能具有显著的垂直分异特征,这是研究山地土壤生态系统和开发利用山地土壤资源的出发点。基于此,我们对贡嘎山的土壤生态功能及其垂直分异特征进行了初步探讨。 Gongga Mountain is the highest mountain range of the Hengduan Mountains in southwest China. It borders Dadu River in the east and Yalong River in the west. It is the source of water conservation for these two important tributaries in the upper reaches of the Yangtze River. At the same time, it is also an important production site for economic activities in the counties of Kangding, Luding and Shimian in the western part of Sichuan Province. Therefore, to develop and utilize the soil resources of Gongga Mountain rationally is not only necessary for ecological balance, but also a requirement put forward by local people’s production and living. To achieve the rational use of soil resources, understand the ecological function of soil is one of the basic conditions. In mountainous areas, soil ecological function has significant vertical differentiation, which is the starting point for the study of mountain soil ecosystem and exploitation and utilization of mountainous soil resources. Based on this, we conducted a preliminary study on the soil ecological functions and their vertical differentiation in Gongga Mountain.
