【摘要】 以可持续发展思想为指导，以优化流域水资源系统结构和功能为着眼点，针对水资源系统存在的问题进行调控，建立适合漓江流域特点的水资源系统调控模式，确保流域水资源满足经济社会协调发展的需要，实现流域水资源的可持续利用，具有重要的理论和实际意义。本课题是广西壮族自治区科技厅下达应用基础性研究课题，同时又得到了国家“十五”城市水环境改善重大科技专项课题的资助。 本课题紧紧围绕水资源的两个主要特征——水质和水量，从时空尺度上展开研究。在水量方面，分析了漓江流域水资源的分布特征和利用特点，指出了流域降雨时空分布与水资源时空需求之间矛盾。在水质方面，分析了漓江流域水环境特征和水环境容量分布利用特点，指出了流域水环境容量的时空分布与需求不相协调的矛盾。 在总结国内外生态需水量研究的基础上，针对水资源丰富地区景观河流的景观与生态的保持，提出了景观生态需水量的概念与计算方法。通过综合考虑社会、经济和环境的需求，采用权重-属性决策法确定了漓江景观生态需水量。在此基础上，进行了漓江流域水资源的供需平衡关系分析。 在充分考虑流域水资源时变性的基础上，建立了漓江水质数学模型，对未来水量变化条件下的漓江水质进行了模拟，并对漓江的水环境容量进行了计算，确定了漓江污染负荷的理论削减量；提出了对于山区雨源型河流应按未来水量条件确定水环境容量的设计流量，在此基础上，讨论了山区雨源型河流水环境容量的动态变化规律。 对漓江流域水资源系统的存在的矛盾进行分析，指出了漓江水资源系统存在的问题，提出了调控水资源系统，实现流域水资源持续利用的思路，即节水优先，科学调水，保护生态，防治污染，加强管理，初步研究了增强水资源持续利用能力的工程技术措施和管理措施。 采用组件式软件技术开发了具有开放性结构的新型GIS平台—DynaMap，使漓江水资源的图形信息与属性信息能够关联起来，实现地图和属性信息的一体化管理，使水资源管理部门可以根据需要，实时更新专业数学模型、实时处理监测数据，达到动态管理流域水资源目的。 论文的创新性主要表现为：在水资源时空尺度综合研究的基础上，提出了河流景观生态需水量的定义和计算方法，采取权重-属性决策法确定最适景观生态需水量；提出了漓江流域水资源调控的系统思想和方法，建立了工程技术与管重庆大学博士学位论文理措施相结合的漓江流域水资源可持续利用模式，并提出了具体的工程技术和管理改革相结合调控措施。关键词:流域，漓江，水资源，水环境，景观生态需水量更多还原

【Abstract】 The research, the research on water resource sustainable utilizing in Lijiang valley, which is one of essential scientific research on water resource exploitation, utilizing and protection afforded by the department of the science and technology of GuangXi Autonomous District for ZhuangZu People, and the 863 major science and technology item administration office which is leaded by the department of science and technology of the Peoples Republic’s of China also give some sustentation fund. The objective of scientific research task is intended to ensure harmony and with requirements for quantity and quality of water as well as for the environment. Aim at enhancing the function of valley water resource system which is directed by the sustaining development idea, the author analyzes the question which is occurred in the valley water resource system, establishes the case system to adjust valley water resource system.The subject matter of this thesis is focused on quantity and quality of water, which are two of cardinal characteristic of water resource. In the aspect of quantity of water, the author analyzes distribution characteristic and utilizing peculiarity of water resource, points out that the cardinal problem of valley water resource is the contradiction of disagreement between the moisture distribution in space-time and water resource requirement in space-time. In the aspect of quality of water, the author analyzes distribution characteristic and utilizing peculiarity, points out that the cardinal problem of valley water environment is the contradiction of disagreement between the water environmental capability distribution in space-time and water environmental capability requirement in space-time.Based on the summary to the research of the Water Required for ecosystem and environment in present, the author puts forward the concert and calculative method for Water Required for Landscape and Ecology in order to keep the landscape and ecology of Landscape River in the area with abundant water resource. The author make certain Water Required for Landscape and Ecology in Lijiang according to the method, after then, analyze the relations between supplying and needing of water resource in Lijiang for the aim of balance.The research builds a mathematical modeled of water quality in Lijiang, and imitates the water quality in Lijiang in the future condition of water flow, calculates thewater environment capacity in Lijiang, brings up the thoughts that it should put the water flow in the future condition as the designing flow of calculating the water environment capacity in the mountainous region with abundant water resource. After then, the author discusses the dynamic capability of water environment in Lijiang.The author construe the conflict between natural system and artificial system by applying the systemic engineering theory, In order to resolve the problems, the author bring forwards some stratagem of management and engineering to revise water resource system, come true water resource sustaining utilizing.For the maintain to needing of management, the author exploit a software platform -DynaMap, which can conjunct the graph information of GIS with the attribute information of MIS, and it can realize unitized management to information of graph and attribute, and it make the system on components GIS is able to achieve updating water environment mathematics model and handling monitor data online, according to administrative demand, and that is helpful to arrive at the purpose to valley water resource dynamic administrating.During the research, the author concludes some innovating ideas and conclusions in some area: the inspect of utilizing disciplinarian in landscape river in the mountainous region with abundant water resource, the author brings forward the definition and calculative method of Water Required for Ecology and Landscape in landscape river; according to the disciplinarian of water quantity for ecology and environment requirement, the author discusses dynamic capability of water environment; according the a更多还原
