| Abstract: | By means of positioning observation. the quantity, the components, the nutrients content of the litters and it's quantity of nutrient restitutions under cypress forests for water and soil conservation were researched systematically. The analysis of monthly change's regularity and the establishment of prediction model for the quantity of litters under cypress forests have been made, and it have been demonstrated that the cypress forests for water and soil conservation play a very important role in improving soil, water supply conservation and water and soil conservation. |
