1 The relationship between soil moisture in various soil horizon and senescence, and irrigation efficiency of different irrigation scheme have been discussed.

2 Direction elements of including Au, U ore information are enriched in cemented soil horizon of the top of accumulated layer, which has not blocked the most elements.

3 The sewage soil disposal experiment is made mainly by using biochemical process of looser permeable soil horizon, and secondly by leaching and adsorption.

4 First, soil erosion modulus can be estimated by using water erosion model, and the maps of soil density and soil horizon thickness can be derived from soil detailed survey data.

5 The SOTER attribute database consisted of four parts; the map delineation information table, the landscape environment table, the typical pedon table and soil horizon table.

6 The eluvial soils on slopes where surface flow occurs are mainly clayey soils with some blocks or debris. They have good grading distribution and a thin soil horizon.
