摘　　要：本文基于对空间尺度分级,构建以“流域景观-景观单元-景观类型”为主体的旅游地学景观分级指标体系,设计“流域-条带高程剖面-高程带”为对应地形参数,在珠峰自然保护区澎曲流域验证了该指标体系的合理性和分析方法的可行性。结果显示,藏南谷地中段区域具有一致发生学规律。景观单元尺度由7个连续不重叠平行单元组成,体现景观分区共轭性。表现海拔4200m以下景观类型多样、4200~4600m多样性减弱、4600m以上景观一致渐变特征。本文为高山型旅游地学景观系统研究和公众了解地学景观提供一种参考。Tourism geoscience is often confined to the geopark field due to the lack of efficient multi-scale spatial cognition method of geoscientific landscape.The application scope of tourism geoscience can be expanded if accurate geoscientific theory and appropriate approaches are used.Digital terrain analysis is good at spatial deconstruction,and digital elevation models provide uniform observational datasets from sink basins to continents.This study is based on the insight to spatial scale classification,constructed a series of indexes named"watershed landscape-landscape unit-landscape type"with the corresponding topographic parameters by"watershed-swath elevation profile-elevation belt".The rationality of the serial index and the feasibility of the analysis method are verified in the Pengqu Watershed of the Mt.Qomolangma National Nature Reserve.The results show that the area covered by the watershed landscape belongs to the southern Tibetan valley,where has the same occurrence law.The scale of landscape unit is composed of seven continuous non-overlapping parallel units,which reflects the landscape zoning conjugation.The scale of landscape type shows a gradual change of mountain landscapes which has the most diversity below the altitude of 4200 m,the diversity is weakened in 4200-4600 m section,and above 4600 m is consistent.This paper provides a theoretical reference for the study of alpine tourism geoscience landscape system,and also builds a bridge for the public to understand the insight between geoscience and landscapes.
