摘要
“黑土滩”的形成有其特定的海拔范围、区域特征和独特的气象条件。整个过程的主导因素是人为过度放牧 ,导致秃斑地的形成 ;害鼠破坏、风蚀、水蚀和冻融剥离等自然因素起到加速“黑土滩”
Based on current investigation results and information available, the present situation, district distribution, natural factors and formative mechanism of 'Black Beach' formed on grassland in Qinghai Tibetan plateau were discussed. 'Black Beach' was formed under certain altitude range, district and meteorological conditions. The dominant factor of its formation was overgrazing, however, the factors of rodent damage, wind and rain erosion sped up the formation of 'Black Beach'.
