Abstract: Tourist facilities have been one of the important sources of environmental problems in tourism areas. The paper inspects the environmental problems in tourism areas from a new perspective of front-back stage structure of service system, and analyzes the negative impacts of both front-stage and back-stage facilities on tourism environment respectively. Based on this the role of the back-stage facilities and functions in tourism environment problems is identified, namely they are one of the most important sources of environmental pollution in tourism areas. With this understanding the paper proposes a new method to cope with the environment problems by applying the principle of front-back stage decoupling, which includes decoupling the front stage and back stage of the individual systems in tourism area, then stripping off those back stage functions related facilities with serious pollution and integrating them to be shared service center of tourism back-stage services which can be environmental—friendly located. This could help to realize higher resource efficiency and facilitate adoption of environmental protection technologies and reduce environmental pollution in the core tourism spots, leading to new ways to problem-solving of tourism environment and sustainable development in tourist areas.

摘要： 旅游设施是形成旅游区环境问题的重要来源。本文从一个新的视角即服务系统前后台结构的视角来考量旅游区环境问题，分别考察和分析了旅游区前台与后台功能设施对旅游区环境造成的影响，明确了后台设施与功能所形成的环境污染在旅游区环境问题中扮演着极其重要的角色，是旅游区环境污染的极其重要的来源。在此基础上本文结合前后台分离的原理，提出了对旅游区各单体服务系统进行前后台分离，将那些环境污染较为严重的后台业务及相关设施进行剥离并整合构建成为旅游后台服务共享中心，实现后台业务的集约化，提高环保技术水平，并对后台共享中心进行环境友好型选址，减少核心景区的环境污染以期有效解决旅游区环境问题，为促进旅游区可持续发展提供新思路。
