| Abstract: |
| The study was conducted to compare soil moisture under different models of land use by field investigation and sampling in Changwu tableland.Results showed that there were great differences in the total content of soil moisture under different models of land use after wheat-cutting date and before rainy season.The content of soil moisture in maize land was greater than that under other models of land use because of recharging of rainwater and fallow of cropland in past year.The averaged content of soil moisture under other models of land use showed significant differences in different soil layers.According to soil moisture in 0～300 cm soil layer, the land uses could be ranked in the order of orchard land > Alfalfa land > farmland.The 200～300 cm soil layer was a transition layer and below the 300 cm soil depth, the land uses could be ranked in the order of farmland > orchard land > alfalfa land.At the same time, different land uses caused different soil moisture profiles.The main differences of soil moisture in farmland could be found in orchard land and alfalfa land, which showed that the types of land use and land coverage were the main factors affecting the depth of water use. |
