摘要
运用层次分析法与熵权法相结合的方法,构建洞庭湖区城镇化综合发展水平和水资源开发利用综合潜力评价指标体系和响应关系模型,分析2001—2010年洞庭湖区城镇化发展与水资源开发利用的主要影响因素、变化特征以及两者响应特征.结果表明:研究期间,洞庭湖区处于城镇化快速发展时期和规模扩张阶段,经济城镇化和社会城镇化水平滞后于人口城镇化和空间城镇化水平,城镇化发展质量和效益有待提升;伴随城镇化进程的推进,湖区用水负荷逐年增大,水资源利用效率和管理水平稳步提升,其中,水资源本底条件和开发利用程度受湖区水文条件的影响更显著.在2001、2002、2005、2006、2007、2009年,洞庭湖区城镇化的发展在一定程度上受到水资源系统的约束.目前,洞庭湖区将面临提高城镇化水平和质量的双重任务,必须改变传统的外延型扩张模式,提高水资源保障能力.
By using analytic hierarchy process and entropy method, the evaluation index system and the response relationship model of comprehensive development level of urbanization and comprehensive development and utilization potential of water resources in Dongting Lake District were constructed, with the key affecting factors, their change characteristics, and response characteristics from 2001 to 2010 analyzed. During the study period, the Dongting Lake District was undergoing a rapid development of urbanization, and at a scale expansion stage. The economic and social development level was lagged behind the population and area increase, and the quality and efficiency of urbanization were still needed to be improved. With the advance of urbanization, the water consumption increased yearly, and the water resources utilization efficiency and management level improved steadily. However, the background condition of water resources and their development and utilization level were more affected by hydrological environment rather than urbanization. To a certain extent, the development of urbanization in 2001, 2002, 2005, 2006, 2007, 2009 was slowed down by the shortage of water resources. At present, Dongting Lake region was confronted with the dual task of improving the level and quality of urbanization, and hence, it would be necessary to reform the traditional epitaxial expansion of urbanization and to enhance the water resource support capability.
