The unique karstification in Karst region forms a kind of earth's surface-underground binary space structure, in natural cause and people
For under factor synergistic effect, karst earth's surface is in soil by discontinuous, soil layer be shallow or even the stony desertification scape of large area basement rock exposure
It sees, and its underground then forms crack, pipe, funnel, vertical shaft, sinkhole, solution cavity under carbonate rock (limestone) corrosion
Deng.Karst Area special " binary " structure and porous media feature, so that runoff in shallow-layer hole (splits) gap, pipe in rainfall
Flowing in road, funnel can take away soil, cause " soil leakage " phenomenon.Karst Area soil erosion process is complicated, water and soil and
Nutrients are missed along Karst Fissures, pipeline, sinkhole etc. to underground not only with the loss of surface runoff, how to monitor noise made in coughing or vomiting
The leakage of this special zone underground and material transport process have become urgent problem to be solved.
Since Karst region soil total amount is limited, Water Conservation Capacity of Five is low, and gap development, Atmospheric precipitation portion (are split) in shallow-layer hole
Divide and generate overland flow in slope surface, partially carries Nutrients along the soil, Epi-karst and conveyer belt of karst aeration zone and hang down
Straight lower infiltration enters underground system by pipeline, sinkhole etc. at low-lying place, but also Karst region underground water is easy by dirt
Dye, it is difficult to administer, and exacerbate the degeneration of karst water quality.In this background, soil and Nutrients are in underground crack karst
Which kind of hydrology path is selected in pipeline, is badly in need of further investigation by key scientific problems such as which kind of hydrology driving mechanisms.
