Primary Environmental Impact and Countermeasures of the Beijing Section of the Middle Route of the South-to-North Water Transfer Project

This paper makes a survey of the major ecological and social environmental problems of the Beijing section of the Middle Route of the South-to-North Water Transfer Project based on the analysis of engineering characteristics and local environmental quality:The impact analysis of the sealed pipe culvert on water quality through the monitoring of similar projects; the impact of rural section on land resources and agricultural protection, including the destruction of surface soil and irrigation facilities, the drop in crop yields;the impact of urban section on city landscape; the obstructions of groundwater flow due to the thin permeable bed at the crossed gulch of the low altitude hilly region and the basically orthogonal of canal water and groundwater; the conflict between large population and restricted land area and the immigration program on local dweller's living. Based on the investigation on the above questions, it puts forward the countermeasures accordingly. It can be used as a reference for minimizing and alleviating the negative influence on the Middle Route Project of the South-to-North Water Transfer.
