Effect of reconstructed micro-slope on soil moisture dynamics in Yunnan dry-hot river valley

Abstract: A preliminary research on the soil water dynamics of reconstructed micro-slope in typical slope in Yunnan dry-hot river valley was conducted by positioning observation and comparative tests .The results show that the seasonal dynamic changes of soil moisture were determined by the amount of rainfall and its distributions within the year .It was usually divided into four stages :evaporation stage before rainy season , wetting stage during rainy season, the stability stage in post-rainy season , and the stability stage in the winter .The soil moisture variety range of the contour trench and contour terrace in wetting stage during rainy stage was much greater than that of the natural slope .On the same high level , the yearly average soil moisture of all soil layers was much greater than that of the natural slope , and the coefficient of variation of soil moisture was smaller than that of the natural slope , the soil moisture variety range of micro-slope decreased with the increase in depth .The soil profile could be divided into three layers :active layer (cv 0.30), less active (0.16 cv 0.30)and stable layer (cv 0.16).Soil moisture lost very quickly on soil surface , it decreased with the increase in depth .Reconstructing micro-slope decreased the loss of soil moisture and increased the stagnation of moisture in soil , which was good for plants'absorption of water .Reconstructing micro-slope obviously improved the soil humidity environment in dry-hot river valley .[ Ch , 3 fig .4 tab .16 ref .]
