Research On Issues Related To Water Resources Allocation In Yangzhou

Yangzhou is located in central of Jiangsu Province, located in the north shore of the Yangtze River, Huaihe plain at the southern end of the City total area of 6634km2, where the area is located in Yangzhou City, along the upper reaches of the central of Jiangsu Province in a total area of 1706 km2. The No.l Document of Central say "CPC Central Committee and State Council on accelerating the development of water reform" put forward in 2011, water is the source of life, to the production, ecological base. Promote long-term stable and rapid economic development and social harmony and stability, we must effectively strengthen water conservancy support capability, to achieve the sustainable use of water resources. China in recent years and severe floods and droughts occur frequently, causing significant loss of life and property, allocation of water resources has become the promotion of economic development and social harmony and stability of the indispensable means.Along the main water source of the Yangtze River and Shaobo Lake. Situation along the river from the point of view of supply and demand, peaceful water wet year, Yangzhou along the river water to meet basic needs, in the event of water shortage in dry years in some areas. Ecological central city dry season river water can not be effectively guaranteed. This article Drought on Water Resources Allocation Yangzhou along the region’s problems, are calculated and analyzed. The main results are as follows:(1)Of the plain area water availability was calculated, and the average local surface water availability factor influencing factors were analyzed. The average surface water availability coefficient with increasing water rate increases. Regulating the same time with the river water depth increases, the average surface water availability coefficient increases. But with the increase in net deep rain and rain, the average surface water availability coefficient decreased.(2) Changes in the characteristics of the water level of the Yangtze River were analyzed to c alculate the water capacity of the region along the Yangtze River. From the information over the years, the trend of substantially the same characteristic level and waveform similarity, there is a certain relationship as a whole. Based on years of data showed that showed a linear relationship, a good correlation between the characteristics of the water level. The calculated polder area along the river most of the water through artesian water meet, the status quo guaranteed rate of 50% of its capacity from 65 million cited m3,75% guaranteed rate of 129.66 million m3,95% guaranteed rate of 167600000 m3.(3)For coupling to mention storage for large-scale engineering calculations and analysis of correlation. In dry years, when compared with the abundance of local water resources, with Hennessy capacity increases drastically reduce the size of the pumping station; when Hennessy capacity of around 9 million m3, with Hennessy capacity increases slowly reduce the size of the pumping station; when Hennessy capacity of 30 million m3, pumping scale was maintained at 917500 m3.
