| 摘 要： | 本试验分别对腾格里沙漠东南缘沙坡头地区流动沙丘和1964年建植的人工固沙植被区生物土壤结皮的地表反照率和土壤湿度进行了同步测定。分析了该区这两种地表类型的反照率与太阳高度角和土壤湿度的相关性,分别提出了地表反照率与太阳高度角和土壤表层(0～2 cm)湿度的经验拟合关系式。结果表明,地表反照率随太阳高度角增加呈指数递减;排除太阳高度角的影响后,地表反照率随土壤湿度的增加也呈指数递减关系;流沙地表反照率对土壤湿度变化的响应要比生物土壤结皮地表敏感。

| Abstract: | The surface albedo and soil moisture of sand dune and biological soil crusts were measured concurrently in field plots of a moving sand area and an artificially revegetated area established in Shapotou in southeasten edge of the Tengger Desert in 1964.We mainly aimed to study the relationships between surface albedo and solar elevation angle and surface soil moisture.The empirical formulas relating surface albedo to solar elevation angle and to surface soil moisture were proposed.The results indicated that ... |
