Pr eliminary Resear ch on Function Optimization of the Tour ism Landscape Ecosystem
旅游景观生态系统功能优化研究初探

Quickly development and spread is the tendency of tourism industry. Therefore, it is a valuable scientific issue to study how to harmonize the human-environment relationship, so as to promote the sustainable development of tourism destination. Based on the theory of landscape ecology, this article proposes that the function of tourism landscape ecosystem is the representation according to the demand of human society and is the result of reciprocity between ecosystem elements, which are tourists, residents and environments. The functions of the tourism landscape ecosystem consist of ecological functions and tourism functions. And the structure of the functions can be divided into relation structure and spatial structure. The former is the interrelation and status of elements, and the latter is the spatial pattern of elements. Furthermore, this article poses the following function characteristics of tourism landscape ecosystem. Firstly, ecological functions and tourism functions interact and sustain one other. Secondly, functions present different degrees in process. Thirdly, the spatial pattern tends to be a network. Fourthly, varying elements will lead to functional changes in the tourism landscape ecosystem. Then, this article analyzes the factors driving the function change. Finally, the methods to optimize the function are summarized, which are the harmonization of elements and optimization of spatial patterns.
