| This article introduced Songjianghe Town, east hillock town located at the Jilin Province Bai Shanshi Fusong County within the boundaries. Because Fusong County's geographical position is quite special, is apart from the Changbai Mountain scenic spot to be near. Along with the recent years Changbai Mountain tourism vigorous development, the Fusong County concentration of industries area which the above two towns and west the Changbai Mountain management meeting pond the area (west i.e. pond area) and was emerging has formed a relative centralism economic center.Travels take Changbai Mountain as the backing, two town two areas (Songjianghe Town, east west hillock town, pond area and concentration of industries area abbreviation) economical rapidly expand. Meanwhile, also unceasingly increases to the cities water supply request. West newly built pond area and concentration of industries area not complete water supply system, but two town's original water furnishing abilities cannot satisfy the economic development and the improvement of the standard of living bring to the water supply demand. The water supply question already became the economic development the restriction factor, hinders its advance seriously the step. Two town two areas set the water supply request in abundance to the Fusong County government. Therefore, the Fusong County government to the peripheral rivers river system's current capacity, the water quality conducts the analytical study, from overall situation angle embarking, decided that take Songjianghe Town as the center, establishes the unified water supply system.In order to cause the project to be more economical, the efficiency, this project first has conducted the investigation and study to two town two area's present water supply present situations, and has carried on the forecast to its future water demand.The Songjianghe Town present water source water quality is good, has certain water furnishing ability 1.5×10~4m~3/d, but the water supply pipe network gets older basically. It is estimated that to 2010 the greatest date water demand 2.74×10~4m~3/d, will achieve to 2020 3.55×10~4m~3/d. East the hillock town also has certain water furnishing ability 1480m3/d, what but uses is the mechanical well pump water supply way, the energy consumption is high. It is estimated that to 2010 the greatest date water demand 0.33×10~4m~3/d, will achieve to 2020 0.46×10~4m~3/d. But west the pond the area and the concentration of industries area still not gave the water facility at present. It is estimated that to 2010 west pond area greatest date water demand 0.72×10~4m~3/d, concentration of industries area greatest date water demand 1.32×10~4m~3/d, to 2020 west pond area greatest date water demand 2.07×10~4m~3/d, concentration of industries area greatest date water demand 3.45×10~4m~3/d.According to two town two area overall supply and demand water budget results: Forecasts in 2010 the highest date water demand for 5.12×10~4m~3/d, water scarcity 3.62×10~4m~3/d; Forecasts in 2020 the highest date water demand 9.53×10~4m~3/d, water scarcity 8.03xl04m3/d. In view of the fact that the loose rivers and streams area present serious water scarcity condition, to satisfy the water supply the request, must carry on the new water works construction. Will therefore establish the water works construction scale in the near future for 4.0×10~4m~3/d; Forward achieves 8.0×10~4m~3/d.Then, according to above investigation and study situation, this project choice's water source has the Dashahe water source and the hill reservoir water source. From the determination as follows two draw out a person into confessing the aqueous system plan: First plan - Dashahe takes the water plan: This project has the water source, the source water distribution pipeline, the water purification factory, the water purification water distribution pipeline and the water distribution pipe line five parts. The second plan - hill reservoir takes the water plan: This project has the reservoir to take the water pump station to expand, the source water distribution pipeline, the water purification factory and the distribution network of water supply four parts.Finally, this article may choose the different water supply system plan which to two water source forms to carry on the technical aspect and the economic aspect compared to elects, by determines the synergy. From technical aspect, main stress to water source water volume, water quality, construction difficulty degree comparison, although two plan have the advantages, but compares favors the first plan. From the economic aspect, mainly from targets and so on project total investment, all-in cost, all-in cost current value, unit run cost and investment recoupment period carries on the comparison, similarly also has the advantages respectively. Elects after the ratio to obtain: The plan one are more than the plan two project total investments, but target first plans and so on working plan period total cost expense, total cost expense current value, average unit cost are lower than the second plan, a plan investment recoupment period compared to plan two short. As soon as the synthesis compares two plans, the plan surpasses the plan two. Establishes this project the recommendation plan is: Dashahe pilot plan.According to this recommendation plan engineering construction's scale, the goal and the content, this article first emphatically carries on the analysis to this recommendation project's financing plan, stresses in the financing structure, the financing cost and the financing risk analysis. Looking from the financing structure, this project capital in cash and debt fund proportion: 30%,70%, although the debt fund proportion is high, but also in reasonable scope, moreover may enhance the capital in cash the fluidity. Looking from the financing cost, this project's fund cost mainly to lend money the cost, is lower than 8% profession returns ratio according to its computation's fund cost, its project's financing cost comparison is low. Looking from the financing risk, its influencing factor has two. First, fund supply and demand risk, although exists, but because this project is the public welfare facility items of basic construction, will obtain government's preferential benefit and the support, corresponding will reduce the fund the supply and demand risk. Second, interest risk. Because this project's fund cost is been big the interest rate change's influence. Therefore, must take seriously to this risk, with the aim of dodging the interest risk well.Next, this article carries on the economic evaluation to the recommendation plan. Mainly from the total cost expense, the profit and the appropriation of profit, profit ability and the repayment ability carries on the appraisal, thought that this plan from the financial angle looked is feasible.Once more, this article carries on the society to the recommendation plan to appraise. This project's construction to this area's urban construction, accelerates the local tourism the development, the regional economies development has the profound influence. Moreover this project and the locus have strong suitable, the social feasibility are mutually good.In summary, passes through to this project construction plan carries on compared to elects with to carry on the economic efficiency and the social efficiency appraisal to the recommendation plan, draws the conclusion: The plan one, namely the Dashahe pilot plan is feasible. |
