| Abstract: |
| The entire irrigation district is divided into three terraces based on the geology and geomorphology of the study area in this research. The water-salt in soil dynamic behavior on the three terraces is real-time monitored on the spot, and the paper analyzes detailedly the change situation of groundwater conductivity along with groundwater depth at different stages and in different distribution conditions using the method of double-factor variance analysis. The results indicate that groundwater conductivity has close relation with water level, and this situation exhibits strong regional characteristics that the increase of EC value on each terrace is along with the rise of the water level, the high EC value always appears in the high water level district
, and there exists significant variation of conductivity on the second terrace. In addition, the outside factors such as the micro-region environment, the human act
ivity, the climate etc., can also affect the dynamical process of groundwater and salt. Therefore, the reduction of the water level in this irrigation district is an important measure to control the soil salinification and is a key to realizing the sustainable development of agriculture. |
