摘　　要：为了解南方红壤区水土流失特点和变化趋势,以浙江省金衢盆地的东阳样区为例,收集当地1990年、2005年两个年份的土地利用情况、植被覆盖度、地面坡度、有效土层厚度等基本资料。文章通过对这两个年份土地利用和植被盖度的变化情况及其成因分析,了解20世纪90年代以来调查样区的水土流失特点及其变化趋势,并针对当地出现的水土流失新问题,提出合理建议。In order to understand the characteristics and variation trends of water and soil loss in the red soil region of southern China, information and data of the land use, vegetative coverage, land slope and effective s0il thickness in the sampling region of Jinqu bason in Zhejiang Province of the year of 1990 and 2005 were collected for Dongyang. This paper, by analyzing changes of the land use and vegetative coverage and their causes, studies the characteristics and variation trends of the water and soil loss in the sampling area since 1990s, and proposes reasonable suggestions for the new water and soil loss issues.
