Study On The Spatial Distribution Characteristics Of Groundwater And Its Exploitation And Utilization In Wudang District,Guiyang

As the main drinking water source,groundwater has been paid more attention and attention.However,with the development of industry and cities in the southwest karst area,groundwater is becoming an important factor limiting its development.Balance the relationship between the two is a big challenge,because of the karst area with the inequality of the karst aquifer water resources and the supply of binary features(exogenous and endogenous water water),and its special way of infiltration medium(dotted with planar)and gap(pipes,fissure and pipeline),that on the one hand,the southwest karst area precipitation abundant;On the other hand,due to the extensive development of karst landform,the surface water leakage is serious,resulting in engineering water shortage.How to develop karst groundwater has become an urgent scientific problem.Based on the theory of karst power system,this study selected wudang area as the research area,and the spatial distribution characteristics of groundwater in wudang area were studied.Through detailed field investigation and data collection and sorting,clear its hydrogeological characteristics,the condition of groundwater resource,the hydrogeological features,resource selection rule of two layer groundwater buried depth,infiltration coefficient,the discontinuous groundwater runoff modulus,ground water,natural recharge,aquifer layer building with six indexes suitable for mutation model of multi-objective decision,calculation and analysis of the study area calculation period of the spatial distribution of characteristic value,based on this,advances in wudang district karst water resources development and utilization of the corresponding countermeasures.Results:1.The annual precipitation of the research area is abundant but karst development,the spatial and temporal distribution of groundwater is uneven,the difference of runoff is obvious and the change is strong,resulting in the situation of engineering water shortage in the research area.2.Certain radioactive-polluted area is obtained by atmospheric precipitation infiltration coefficient method in natural groundwater recharge 95% assurance rate of 127.1016 million m3/a,75% assurance rate of 153.4634 million m3/a,50% assurance rate of 174.1762 million m3/ a,the groundwater resources in the computing segment is respectively:?1 for 12.9519 million m3/a,?2 for 5.5605 million m3/a,?3 is 11.469 million m3/a,?4 is 6.7583 million m3/a,?1 of 22.61 million m3/a,?2 is 14.7259 million m3/a,?3 is 8.8571 million m3/a,?1 of 4.0013 million m3/a,?2 is 32.0465 million m3/a,?3 is 7.4444 million m3/a.3.Get through the catastrophe model calculation:spatial distribution of groundwater research value between 0.4685-0.8414,suitable for the use of rainwater collection development model has 14,III1;Karst is suitable for surface water development and utilization mode III2,II1,I2,III3,I3,II3,II2 for shallow development I have used the groundwater model1,the whole Wudang district development and utilization of water resources for the collection and utilization of rainwater and surface water of Karst development and utilization of two modes...
