中文摘要：

随着全球气候变化以及人类活动的影响,水资源系统的适应性已经成为研究热点。以湘江流域水循环-社会经济-生态环境耦合形成的水资源复合系统为例,从协同学理论出发对复合系统的各个子系统设置序参量,详细阐述了适应性评价模型的建立和评价过程。采用基于贴进度理论的方法计算了各个序参量的组合权重,最后使用综合评价法计算了湘江流域水资源系统的适应度。研究结果表明：湘江流域水资源系统适应性总体状况良好,与实际情况相吻合。评价结果为湘江流域水资源的可持续利用提供了可靠的依据。

英文摘要：

With the global climate change and the influence of human activity,water resources adaptability has become the concerns of researchers.The coupled water resources system of water cycle-social economy-ecological environment of Xiangjiang River Basin is taken as an example.We set order parameters of each sub-system based on synergetic theory.The establishment and evaluation of the adaptability assessment model of water resource system is described in detail.Using the method of closeness degree,the weights of each order parameters are obtained,and the adaptability of the water resources system of Xiangjiang River Basin is calculated by comprehensive evaluation method.The conclusion shows that the adaptability of the water resources system of Xiangjiang River Basin is at a good state,which is consistent with the facts.The assessment of the water resources system adaptability can provide a technical guidance for the sustainable development of the water resources in Xiangjiang River Basin.
