Investigation on rules of groundwater and salt dynamical in Luohui trench irrigation district
Journal Title: Science Paper Online - Year 2007, Vol 2, Issue 2
Abstract
To comprehend the rule of groundwater dynamical thoroughly is one of the basic theories to solve the problems of the soil salinization and ground water pollution. Based the geology and physiognomy about Luohui trench, this research divides the entire irrigation area into three terraces. Monitors the groundwater and salt dynamical on the spot in 2005, and uses the“Two-Way ANOVA”methods, analyzes concretely the change of groundwater conductivity along with the groundwater depth in differ times and vary from distributing condition. The result indicates, the variation of groundwater conductivity has a great relationship with the water level, and demonstrates very strong regional characteristic: Each terrace EC value increases with rising of the water level, high EC value appears in the high water level area, the conductivity of high water level of the first terrace exists a variation. But the outside factors include the micro-region environment, the human movements and the climate also can affect the groundwater and salt dynamical process. Therefore, reduces the water level of this irrigation district is the important measure to control the soil salinization and the key to realize the agriculture development.
