摘要：Erosion constitute one of constraint for dryland farming in Indonesia. In dryland farming in transmigration sites, almost all factors led to the high rate of erosion: high intensity of rainfall in a short period, steep slope, opening of forest landcover for cultivation, and the absence of conservation efforts. This research was conducted to determine the soil conservation measures according to spatially calculated erosion. The calculation of the erosion rate was first carried out spatially, so that appropriate conservation could be recomended. The study was conducted in Rantau Pandan SP-3, Jambi Province. The amount of erosion was calculated using the method of Universal Soil Loss Equation (USLE) (Wischmeier & Smith, 1978). The results of the research showed that the magnitude of the maximum erosion in transmigration site of Rantau Pandan SP-3 ranged from 0.004 tonnes/ha/year to 496.97 tonnes/ha/year. The magnitude of this erosion is the maximum erosion in some land use types in the settlement and other part of land. Lands in Rantau Pandan SP-3 have an erosion hazard rate which were classified as mild to very severe. Tolerable erosion at Rantau Pandan SP-3 ranged from 29.7 to 35.8 tonnes/ha/year, taking into consideration the 300 years lifetime of soil. Spatially, erosion calculation can be done using several assumptions in accordance with the observations of field conditions. In each land use polygon can be assigned a maximum amount of erosion, which can then be used for the determination of soil conservation techniques. As erosion considered is the maximum erosion, protection against erosion can be guaranteed.
