摘要：Soil erosion, gullying and landslides have been recognized as the major environmental threats in the MoldavianPlateau of Eastern Romania. Five stages of land degradation over the last two centuries can be depicted, namely:i) a preparingstage for future land degradation (1829–1999) when the most dynamic change of the native landscape was recorded; ii) atransitory stage (1900–1920) associated with the extension of the cultivated land up to 48% of the total area; iii) the climaxstage (1921–1970) defined by both the traditional up and down hill farming and the peak rate of land degradation during1960’s; iv) a decreasing tendency of land degradation (1971–1990) as a result of the extension of conservation practices andthe rainfall pattern; v) the present-day revival of land degradation associated to the Act no. 18/1991 when up and down hillfarming under small plots is on the screen again. The main objective of this study was to define the process:based erosionand sedimentation by providing quantitative information from long-term field measurements in small catchments.
