摘要
通过对福建沿海土壤性质的调查和风蚀定位观测,发现从每年6月至翌年3月的强风使土壤水分的蒸发量超过降雨量。在风蚀和水蚀的作用下,沿海土壤演变为沙土,沙质红壤土,沙质海泥土,风水蚀堆积土和风水蚀红壤。土壤风蚀和演变的结果导致土壤粘粒含量、土壤保水保肥能力降低和土壤质地粗砂化。风蚀的发生发展受植被覆盖、耕作活动、土壤质地、土壤水分和风力等因子的影响。
Through the survey of soil property and the observational fixed spots on the coastal hilly soil of Fujian province it is found that the strong wind from September to next April makes the evaporation of soil moisture exceed the rainfall in the same period. Under the effects of wind and water erosions the coastal hilly soil evolves into sand soil, sandy red soil, sandy muck soil,sediment soil by wind-water erosion and red loam by wind-water erosion.The wind erosion danevolution of the soil results in the decrease of clay particals content in soil and the capability to conserve water and fertility, and the coarse texture of soil. The occurrence and development of wind erosion is affected by p]ant cover, tillage, soil texture, soil moisture and wind power, etc..
