The Black Tiger Landscape Database To Permit Expand To Permit Of The Necessity And The Possibility Research

This thesis made a research on increasing the capacity of reservoir project. The implement of "the reservoir capacity increasing project ", is the comprehensive utilization and rebuilt not only of Heihushan Reservoir, but also of many reservoir of middle and small size built in 1950s, which had many problems such as low technique level, poor in quality and project safety. It is typical, applicable and operable. technique level is low,the engineering quality is bad,the safe suffer from the comprehensive reformation that has another and puts forward,make use of a project, not only have typical model, but also have the extensive application and operability, for from now on the water resources the management has important meaning with comprehensive exploitation.This thesis aims at a nervous problem of the rigorous water resources that the current our country and green state face, analyzing the water resources to run short of reason,endanger,and surround the reformation exploitation of the reservoir, launch extensive but thorough of the investigation and the theories study.Aim at the geography scope,the hydrology weather of the black tiger landscape database etc. natural history condition, increased to permit to expand to permit to carry on the system investigation to the reservoir, go deep in to analyze the disease insurance reservoir to expand to permit to increase to permit of the necessity and urgency, evaluated the foundation condition,profit ability and economy and social performance of the item construction completely.According to the item programming, went deep in to analyze reservoir to expand to permit to increase to permit to the local ecosystem environment,agriculture produce,water conservancy construction,defend the huge function of the safety, then synthesized argument reservoir to expand to permit can not only reform the disease insurance reservoir, but also resolve a farmland irrigation irrigation,the city area to produce a life to use a water and arouse the problem of[with] comprehensive kit etc. of the whole city water conservancy facilities, various argument the reservoir expand to permit to increase to permit of the necessity and the possibility.This thesis to the item research that the reservoir expands to permit to increase to permit, not only absorbed to draw lessons from the successful experience way of doing in the current reservoir reformation completely, the main dam that put forward reservoir to expand to permit to increase to permit an usage protects an ascent,vice- dam to cut seepage ,purdah to infuse syrup,spillway to set up strobe and turns on water the hole extension etc. the item measure, put forward the engineering construction concrete measure systematically, also to carry on to the water conservancy construction measures, such as maze embankment and the rubber dam...etc. more analytical, put forward the possibility opinion of[with] innovation.In the meantime, this text still combines reservoir to expand to permit to increase to permit, the kit analysis was also put forward infusing a comprehensive reformation,the mountain area reservoir of area to establish a kit,the city area water supply to synthesize to make use of etc. measure, not only have the very strong maneuverability,usage and instruction, but also have to certainly run before sex and farsighted programming, can draw lessons from sex for winning the comprehensive exploitation of the small scaled disease insurance reservoir to have.
