从游客环境容量到LAC理论——环境容量概念的新发展

From Recreation Carrying Capacity to LAC Theory——On the New Development of Environmental Capacity Concept

LAC(可接受的改变极限)是从游客环境容量概念发展而来的,用于解决资源保护和旅游发展之间矛盾的理论。这一理论在很多国家的规划和管理中得到了广泛的应用,取得了良好的效果。本文阐述了从环境容量到LAC理论的发展过程,描述了LAC理论的九个步骤,简要介绍了LAC理论的衍生技术方法。

LAC(Limits of Acceptable Change)is a theory developed from the concept of 'carrying capacity' to deal with the conflicts between resource protection and tourism development. It has been applied in the planning and management process in some advanced countries around the world. This paper generalizes how LAC is developed from recreation carrying capacity, describes the nine steps of LAC history, and introduces briefly some models derived from LAC theory.
