摘　　要：以1989-2001年通过盘江桥、高车断面的输沙量资料,分析北盘江流域的水土流失状况。结果表明,喀斯特地区的水土流失特征具有非线性的复杂关系。为了改善北盘江流域的生态环境质量,有必要对石漠化过程和人类活动方式采取适当的调控措施。通过对不同尺度范围可行性的探讨,认为按尺度层次划分的坡地改良方式,可能是北盘江喀斯特地区石漠化治理较为有效的途径。Based on the runoff and sediment transport data obtained at Panjiangqiao and Gaoche cross-sections from 1989 to 2001 the soil loss in the Beipanjiang basin is analyzed. It is proved that the soil loss in karst region is of very complex relation with non-linear characteristics. It is necessary to take suitable measures to control the process of rock desertification and to adjust human's activities in order to improve the environmental quality. Through the study of the feasibility at different scales it is believed that the ameliorating way of slope field in accordance with division of scale grade may be effective method for the control and treatment of rock desertification in the Beipanjiang basin.
