In the relationship between humans and the environment,all human activities depend on the geographical environment,which serves as the spatial place and material foundation for human life.This study provides a perspective on the human-environment relationship,using a case study of the Dashanbao Mountainous Outdoor Tourism Planning Area in Zhaotong,Yunnan.This study employed methods such as literature review,on-site investigation,and GIS spatial analysis to analyze the functional characteristics of the regional subject,spatial structuring,and spatiotemporally variable ordered processes of Dashanbao as a tourism destination from the perspective of human-environment relationships.The results indicate that under the guidance of the human-environment relationship system philosophy,the construction path of the“ecological space,production space,and living space”includes three main aspects:(1)The formation of five major project blocks and five functional zones to meet the diverse needs of different groups;(2)The establishment of a"multi-core module"structure optimizing the spatial layout of the tourism destination;and(3)With the changes in space and time,the convergence of elements in each block can form a composite mountainous outdoor tourism space with the characteristics of“ecology,life,and production”.The results of this study provide a scientific basis for promoting the sustainable development of tourism regional systems with mountainous characteristics. 展开更多
