Mr.zhang Sustainable Utilization Of Water Resources Supply And Demand Balance Analysis And Research

With the progress of human civilization, the requirement for water resources is growing.but the water resources available for human use will not increase.Even man-made pollution and other factors have reduced its quality and utilization.Additionally, the world’s freshwater resources is unevenly distributed. The People live location and distribution of water without commensurate, so that the contradiction between supply and demand of water resources is great, especially in the industry and population concentration city, this contradiction is more prominent.By a systematic analysis of the regional water supply and demand balance, propose the measures to solve the existing problems in the process of Water resources development and utilization,then a fundamental solution to the contradiction between supply and demand of the local water resources. The study of the sustainable use of water resources has great significance to promote the coordination of regional society, economy and environment.and sustainable development.The sustainable use of water resources as the guiding ideology.on the basis of analysis of water supply and demand balance, combine sustainable use of water resources with socio-economic development and ecological protection and establish the comprehensive evaluation index system of the sustainable use of water resources in pursuit of economy, society and environment to maximize overall efficiency in Panzhihua City. Through analysis of surface water and groundwater, thus calculating the available water resources of Panzhihua City. By the survey on water supply.socio-economic water use. the status quo annual water analysis, water resources development and utilization of analysis and the status quo of water resources supply and demand analysis, reveal the existing problems of water resources development and utilization, and the contradiction between supply and demand for water resources to provide a realistic foundation for the optimal allocation of water resources in Panzhihua City.By predicting the population of the Panzhihua City level, the tertiary industry added value and other indicators of water in enhancing the water quota under water saving conditions,calculate the level of planning required.According to the planning level water demand and reference the relevant planning to develop a conventional water sources and unconventional sources of water supply planning, and calculated the planning level of the total available water.To protect the water resources optimal allocation results can be successfully achieved, develop water conservation implementation plan and increase water conservation measures and water quality monitoring plan to improve the water security measures.Water supply protection capability; socio-economic development and ecological protection is basic coordination.and holistic integrated water resources constraints eased.
