Analyze On Restraint Of Water Resources And Urban Sustainable Development

Sustainable development is a new development strategy. As a core of the economic development of countries and regions, Cities.are the key to achieving sustainable development.Accelerating the pace of urbanization is an important strategic measures for achieving the third-step strategic goal.The problem of water resources for sustainable urban development in China is generally the "bottleneck" problems.Along with the accelerated process of urbanization, urban industrialization and modernization level,the increase in the number and size of cities and the continued expansion of the contradiction between supply and demand of water resources in cities has been quite pronounced,hence many new problems.To ensure sustainable economic and social development of our city, we do the research of urban sustainable development and urban comprehensive utilization of water resources under scarce water resources is of great significance.Based on the relationship between water resources and urban sustainable development, describe the role of natural resources in economic sustainable development and the line of economic growth, the resource constraints on economic development issues under scarce resources in the big system of resources and economy.Next, put the issue of sustainable development in the process of urbanization, analyse the value and scarce characteristics of water resources, the macroeconomic impact of water resources in urban development, the problems and causes that exist in the development process.On this basis, analyse the restraint roles of water resources in urban sustainable development from the functions of cities,ecological, economic and laws etc.Take the cities in northwest area for example,by using the threshold model analyze the total economic amount of urban development and the corresponding thresholds of urbanization level under the constraint of water resourc. Finally, take urban water resources management as a breakthrough and put forward the strategy for urban sustainable development That it is necessary to raise the use efficiency of resource and build conservation-minded citiese in order to promote economic and social sustainable development and solve the problem of shortage of urban water resources and other natural resources., which are the basic requirements for implementing the scientific concept of development and building effective cities.
