Abstract:

The hydrochemistry type, spatial distribution and the cause of formation about the river were discussed by analyzing the hydrochemistry data which from the karst springs, the surface water and the underground water monitoring stations in Banzhai. The results showed that the pCO2 of the karst spring was high, and the concentration of the CO2 in 20cm depth was 38000ppm in the area of Laqiao，which was 30 times higher than the area of returning farmland. The surface retained water which was formed by the land cover in the forest and karst aquifer make up a multilayer hydrogeology space structure, which increased discharge storage largely and decreased the water release. Then the arid landform caused by an unequal distribution of rainfall was improved greatly. The soil in maolan was much less than in not-karst zone, although the maolan in forest area, where the process of karst in the forest area was not strong. The pollution of the MaoLan Natural was mainly from agricultural activities such as the effect of fertilizer and domestic sewerage etc. The dynamical change of hydrochemistry in epikarst spring water was influenced by surface environment and rainfall greatly. The hydrochemistry of underground water was affected by the diluting processes of rainfall obviously.
