초록

The purpose of this study is to develop a pipe type soil sampler that can easily collect soil cross section servey and soil samples to conduct ecologicalenvironment surveys while minimizing ecological disturbance in the area subject to soil survey.
Furthermore, this study develop the exponential type estimation specific weight formula (ESWF) that uses pipe type soil sampler to easily carry outsoil cross section survey and soil sample while estimating the specific weight of the area using water content and soil sample length variation ratio(SLVRs) and to obtain apparent specific gravity, hardness, and max. porosity which are used as growth of corps and ecological environment index.
The calibration results of ESWF showed a high degree of significance, with NSE for actual specific weight ( ) and calibration estimation specificweight ( ) 0.95, R2 for 0.954, and RMSE for 0.051. The verification results of ESWF showed a high significance, with NSE for actual specific weight( ) and verification estimation specific weight (  ) 0.881, R2 for 0.978, and RMSE for 0.055.
