| Abstract: |
| The change of land use and land management takes crucial roles on environment of soil moisture content. The various land use and management were collected, such as peak period, aged orchard and cultivated land from returning orchard on three terrains, i.e. tableland, slopeland and ridgeland, to analyze the effect of change of land-use and management on soil moisture content in soil profile in the form of measuring distribution of soil moisture in the 0～400 cm (0～600 cm on tableland). The results show that: on the slopeland and ridgeland, soil moisture content of peak orchard and aged orchard is close to crop wilting humidity, approximately equalled to 10%. On tableland, soil moisture in peak orchard and aged orchard is about 15%. For cultivated land aged fo
ur years after returning orchard, the water storage in 0～400 cm on slopeland increases significantly. On tableland and ridgeland, compared to aged orchard the soil water storage in profile can not reach significant level although it increases; and for cultivated land aged four years after returning orchard, the soil moisture in 60～140 cm and 220～400 cm in profile on slopeland and ridgeland increase significantly, compared to 220～600 cm on tableland. |
