摘要
通过2017年4月、2017年9月两次野外调查,利用堆龙德庆区1:1 000 000数字地貌图、TM影像数据、气候分区图及Google Earth等资料,借助GIS制图技术,完成了拉萨市堆龙德庆区荒漠类型分布图,在分析高寒地区区域环境特点的基础上,利用气候条件、海拔、物质组成、地貌形态、地貌成因及植被盖度等指标,建立了堆龙德庆区荒漠分类体系,并将堆龙德庆区的荒漠区域分为2个一级类型,5个二级类,14个三级类,17个四级类,为高寒地区的荒漠化分类系统的建立提供基础性研究。
Based on field investigations in April 2017 and September 2017 and the help of GIS mapping technology, Duilongdeqing 1:1 000 000 digital geomorphologic map, TM image data, climate zoning maps and Google Earth material were used in this paper to draw the desert type distribution of the Duilongdeqing county. According to the basis of analyzing characteristics of the regional environment in the cold area, indexes of altitude, climate condition, material composition, morphology and morphogenesis and vegetation coverage were used to establish the desert classification system of Duilongdeqing county. The desert region of Duilongongdeqing county was divided into two primary types, five secondary classes, fourteen levels of three classes and seventeen levels of four classes. Thus, the desert classification system in the high cold region was preliminarily established, and a basic research was provided for the establishment of the system for the desertification classification in the alpine region.
