基于人地关系的生态旅游地域系统演变定量分析

本研究通过建立人类活动无序度和生态环境承载力评价指标体系和模型,用简化系统结构关系的方法测算生态旅游地域系统熵值,以此来分析生态旅游地域系统的功能状况;生态旅游地域系统中人类活动主要是旅游者的旅游活动、当地社区和居民的活动和当地旅游业活动三个方面,构建了27个具体指标来评价人类活动的无序度;生态环境承载力主要通过自然基础、生态系统、水资源和大气环境四个方面共8个具体指标来测算。最后通过生态旅游地域系统熵变即两个不同时刻人类活动无序度熵变和生态环境承载力熵变差值,来判断生态旅游地域系统在时间断面上的演变方向和可持续发展能力。

QUANTITATIVE ANALYSIS OF ECTOURISM REGION SYSTEM EVOLUTION BASED ON MAN-LAND RELATIONSHIP

The ecotourism region system is a special man-land system according to man-land relationship.The motion condition of the system is estimated by entropy of the system.The entropy of ecotourism region system is calculated by the difference between absolute value of the plus entropy brought from the disorder of human activities and absolute value of the negative entropy produced by eco-environment carrying capacity.The evaluation and model of the disorder of man movements and eco-environment carrying capacity are set up in the research.The entropy of ecotourism region system is counted with the way of simplifying the system structure relationship.The function state of Ecotourism region system is analyzed by it.The human activities include the activities of tourists,inhabitants,local community and tourism industry.The disorder of human activities is evaluated with 27 indexes from the activities.The eco-environment carrying capacity is calculated with 8 indexes from the nature basis,ecosystem,water resources and atmosphere environment.The evolvement direction and the sustainable development capacity are estimated by the entropy change of ecotourism region system which is the difference between the entropy change of the disorder of man movements and the one of eco-environment carrying capacity in time range at last.
