九龙江流域城市化进程与水资源耦合关系的定量辨识

Quantitative Identification of the Coupling Relationship Between Urbanization Process and Water Resources in Jiulong River Watershed

正确识别城市化与水资源利用所处的发展阶段及辨识二者之间的耦合关系是研究特定时期和特定地域人水关系系统的前提条件.针对九龙江流域漳州、龙岩和厦门三市的城市化水平、用水总量、用水效益和人均用水水平进行了定量分析,并在此基础上验证了水资源约束力的存在,提出了测量水资源约束力指标的方法.结果表明,龙岩和漳州目前处于城市化的中期阶段,而厦门已经处于城市化的后期阶段;漳州和厦门在城市化进程中存在一定的水资源约束力,并且漳州约束强度高于厦门.综合分析得出龙岩城市化发展与水资源环境耦合作用过程处于相对平和的磨合期,漳州处在拮抗阶段,厦门则处在磨合与高水平协调阶段之间.

To properly identify the stage of development and coupling between urbanization and water utilization is the premise of re search on relations between people and water in a specified period and specified region.The urbanization level, total water utilization, water use efficiency,and water consumption per capita in three cities in the Jiulong River Watershed, Zhangzhou, Longyan, and Xiamen,were quantitatively analyzed.Subsequently,the constraint on water resources was verified to be present and a method was proposed to measure it.Both Longyan and Zhangzhou were shown to be in the middle stage of urbanization,and Xiamen was shown to be in the later stage of urbanization at present.During the processes of urbanization of Xiamen and Zhangzhou, there had been constraints on water resources,with the intensity of Zhangzhou was higher than that of Xiamen.Through comprehensive analysis, the coupling between the urbanization and water resources for Longyan was in a relatively peaceful adaptation stage.Zhangzhou was in the resistant stage,whereas Xiamen was in the phase between adaptation and advanced harmony.
