根据吐鲁番2001-2011年旅游-经济-生态环境系统各指标的相关数据,利用主成分分析法,得到各个指标的相关权重,以此构建了相关的综合评价函数,并引入耦合度及耦合协调度模型,对吐鲁番地区的旅游-经济-生态环境的耦合度以及耦合协调度进行了实证研究。结果表明:吐鲁番地区在2001-2011年间,旅游-经济-生态环境的耦合协调度类型以旅游超前发展型逐步转变为以经济超前发展型为主,由三者基本协调状态转为旅游与经济的发展超出了生态环境承受阈值范围的状态,其耦合协调关系处于颉颃状态,生态环境成为制约耦合协调度提高的关键因素。

The coupled human and natural systems were formed through continuous interaction between human activities and nature composition. Under the guidance of this theoretical framework, we studied that how the human activities affect the ecological environment in Turpan area. As we all know, the special climate of Turpan was the preconditions for our this study. Based on the data of Tourism-Economy-Ecological System in Turpan area from the year 2001 to 2011, which was from Statistical Yearbook of Xinjiang, Statistical Yearbook of Turpan and Field investigation in Turpan, then we used principal component analysis and SPSS17.0 software to determine the relative weight of each index to construct tourism-economy-ecological comprehensive evaluation function, and then used the model of coupled degree and coupled coordination degree to calculate each degree of tourism-economy-ecological system in Turpan area. Compared the values to the classification of coupled coordination degree, we got the types and characteristics of coupled coordination degree of tourism-economy-ecological system in Turpan area. The result showed that during 2001 to 2011, the type of coupled coordination degree in tourism- economy- ecological system was changing from tourism-advanced to economy-advanced, and the condition of the system was changing from harmony to disharmony that was the development of tourism and economy go beyond the threshold the ecology could stand. And the system of the coupled coordination was in antagonistic state, the ecology was an important factor in restricting an elevation of coupled coordination degree.
