| 摘 要： | 土壤水分是影响土壤侵蚀的重要因素之一.以晋西离石王家沟流域为试验基地,收集了1994年7～9月份的土壤水分逐日观测数据和与之相对应的降雨量、气温、空气湿度、蒸发量等气象因子观测资料.通过分析,得到了较高精度的用于预报该地区梯田、坡耕地、荒坡地、弃耕地、人工草地、沟坡林地6种不同地类土壤水分的经验公式,为各种地类的土壤水分预报以及土地生产力评价、土壤侵蚀规律研究提供了较为理想的土壤水分计算方法.

| Abstract: | Soil moisture is one of the main factors influencing soil erosion. The daily observation data of soil moisture from July to September in 1994 was collected at Wangjiagou watershed, a test base of Lishi County of Western Shanxi Province, as well as rainfall, temperature, air humidity and evaporation, etc. . Through analysis, the paper draw out 6 empirical formulas which could accurately predict soil moisture in terraced field, slope farmland, slope wasteland, abandoned farmland, grassland, and forest land in gully slope in the area. These formulas provide a perfect method for calculating soil moisture in prediction of soil moisture in all kinds of land, evaluation of land productivity and study on the law of soil loss. |
