Study On Control Plan Of Water Imported Areas In The South-to-North Water Transfer Project Of Langfang

ater is the source of all living things in the nature of life,is the basic elements of human survival environment.Water is the important foundation of social economic development and human civilization.Langfang caused by natural geography and climate conditions,the problems of water resources,Have plenty of water(flood)problem,also has less water,serious shortage of water resources,and the problem of water pollution.In the 21 st century,the shortage of water resources is still seriously restricts the langfang economic and social development.In surface water with water cut down,wastewater quantity increased,the surface water pollution,soil pollution,seeped into the underground cause water shortages,such as shallow groundwater pollution ecology and deterioration of water environment as the main sign of water crisis,has become the characteristics of local water resources in langfang city area.From a long-term point of view of sustainable development,water is the basic way to solve the crisis of water resources in langfang city.Therefore,pressure mining through some measures to solve the problem of groundwater over-exploitation langfang south-to-north water transfer project,is the urgent task of current water resources management.At home and abroad based on the summary analysis of groundwater,underground water pressure,water environmental restoration,the tapping combined with the local water environment and geological environment and the ecological environment problems,as well as the progress of shut-in pressure mining work,study of underground water pressure by tapping langfang to discuss:(1)analyzed the harm of groundwater,mining pressure,the significance of exploitation in mining area pressure on groundwater environmental restoration,the research progress of the common exploitation area,water environment,geological environment and water ecological environment question has carried on the system analysis.(2)through the local geology,climate,water resources in langfang city conditions such as investigation and analysis,to solve the water supply of water resources,water demand and water supply and demand.To determine the different planning level years underground hydraulic mining and underground water pressure CaiLiang target.(3)in view of the situation of excessive groundwater tapping in langfang city,analyzes the pressure of the urgency of the mining,put forward by diversion,rain flood resources utilization,agricultural water saving engineering,establish a sound monitoring system and the evaluation of the evaluation system of engineering control and management control measures to reduce groundwater resources,so as to realize thesustainable utilization of groundwater resources.
