Research On The Construction And Operation Management Model Of Silt Dam In Loess Plateau Area

The paper proposed mechanism which benefits realization of modern management and measures of promotion and application, based on the comprehensive summary of construction management model and operation management model of silt dam on Loess plateau and analysis of existing problems, self-advantages and self-disadvantages in the process of management. The research indicates several advantages of managing engineering construction item regarding professional basin institution: 1.The procedure of organization and management is simplified and systematical. There are less links and it is easy for us to implement plans, documents and related instructions of higher authorities; 2.Be able to make full use of technical advantages of basin management institution. There are more technical workers and many obvious advantages such as research, construction and management; 3. Be more standard to manage construction capital, without the situations such as occupation, misappropriation and unreasonable expenditure. The main disadvantages is that it is difficult to develop more powerful coordination effects to resolve the problems such as communications with local government and the public and occupation of field.Regarding local water (water-soil conservation) administrative department as construction unit, the main characteristics shows in the following aspects: 1.Although area (city, pledge) water conservation bureau are juristic persons, affected by traditional management, their status was not manifested fully and they were"the second passers"at best; 2.The implementation of engineering supervision system has improved quality of engineering construction greatly and basically ceased illegal behaviors such as false reporting, concealing reporting the number of governing measure. But because of the effects of management, there is a certain difficulty in implementing supervision work independently, autonomously and publicly; 3. To present investment standard and composition of capital source, the conditions of executing bidding system is not mature, especially because of the existence of lots of characteristics such as less capital, tremendous quantity, wide platter, non-concentration, seasonal strength, it's even more impossible to implement hillside governing engineering. Under the magnificent situation of construction of new countryside of socialism, each irrigation and water conservation engineering referred to countryside construction will be implemented considerably. The two construction model must co-exist in a certain period, and will play more important role in management. From the recent situation of construction management, it's more reasonable to regard irrigation and water conservation department of county as construction unit. The key point is to reinforce supervision power in order to put limited construction capital on the engineering construction, make engineer display long-term benefits stably.Furthermore the research consider that it is reforming operation management of silt dam that makes it revive and display comprehensive benefits of blocking and silting putty, and planting, etc.. During the implementation of reforming property right of silt dam, we had better operate revolving"three powers", that is transforming ownership, loosing construction power, stimulating operation power, and transforming towards direction of"oneness of three powers"regularly, making"obligation, power, benefit"highly integrated virtually. Successful land joint production contract management system indicates that it is depending on the public to manage their own things that it's possible to manage well, drawing on the management experience of other successful projects, proposing the establishment of demonstration management committee of silt dam, exploring management mechanism of sustainable development, drafting rudimentary a set of measures concerning management operation of silt dam and obtaining certain demonstration effects after implementing the measures in hilly and gully region of Loess plateau。In view of the effects and status of silt dam in hilly and gully region of Loess plateau, it is suggested that we had better still strengthen research and propose more reasonable and operational management measures and system, promote management measures and system gradually, especially increase demonstration area and number of silt dam in Shaanxi,Shanxi,Neimenggu and Gansu province,etc. where silt dams are widely distributed. The measures above would display essentially important impetus to promote management maintenance and exploitation development.
