| Water resources is not only bases of basic natural resource of controlling ecologicalenvironment and substance bases of all society development, but also is a strategicaleconomical resource. It is also an important parts of a national comprehensive power.World water resources comprehensive assessment (1997.1) of United Nations reported thatwater crisis will seriously restrict global society and economy development in 21 century,and might lead to conflicts among countries. Now, national water crisis has not been solvedfor a long period of time, furthermore it is becoming to yield severe water crisis. China feed its population which account for 22% of world population with 6% ofworld fresh water and 9% of world arable area. So, China has made a great contribution tothe world water supply and demand balance. It is one of thirteen water resources per capitashortage countries in the world. It's water resources states are waterlogging, water shortage,water dirtiness and water pollution and ecological environment unbalance. Therefore,studying on harmonious sustainable development path among population, society,economy, environment and national stratagem of water resources and other scientifictopics in relation to water resources in 21 century have become one of important researchsubjects which governments pay a great attention to in the world. Sustainable waterresources are one of important multi-discipline comprehensive research fields in thiscentury. Indicators system and assessment methods for sustainable utilization in relation towater resources are one of core subjects. At the present time, some works about the fieldshave been investigated and made some progress. These progress are very beneficial toperfect the indicators system and assessment methods for sustainable utilization in relationto water resource. But, generally speaking, the research in the fields is still in its primaryresearch stage. So far, there has no a assessment indicators system which can be widelyaccepted by water resources experts. In this thesis, based on existing research states andmain problems about the field at home and abroad, taking Shaanxi Province as researcharea, using sustainable development theory, we want to establish the indicators system ofsustainable water resources and study assessment method of the indicators system. There are nine chapters in this thesis. Chapter one is about a comprehensivedescription of some progress and main shortcoming in sustainable development and　Vindicators system of sustainable water resources at domestic and abroad, presents researchcontents and methods and technical ways. Chapter two presents sustainable waterresources utilization system structure, including defining and basic research tasks andtargets of sustainable water resources utilization system. Chapter three describes thegeneral situation of natural geography and climate and society and economy and waterresources utilization and environmental protection in Shaanxi Province. Chapter fourselects indicators and presents the indicators system concept framework for sustainablewater resources utilization system which consist of water resources society and economyand environment subsystem according to Entity-Relationship Approach (Peter Chen,1976).The sustainable water resources utilization system name as RSWRS system. Based onBossel's basic orientor indicators and sustainable development idea, these indicators arefallen into six categories basic orientor indicators, i.e. Existence, Effectiveness, Freedomof action, Security, Adaptability and Coexistence. Using benchmark selecting method andoptimum selecting methods, this thesis gives the basic orientor indicators criterias whichclassified as the lowest level, low leve, middle leve, high leve and the highest level.Chapter five uses Bossel's assessment criterias and deviation sum of squares withreference state of basic orientor indicators to determine the weight, bases on Bossel'sOrient...
