摘要

. 吉里登加集水区位于婆罗浮屠寺西南5公里处,是一个被指定为缓冲区的地区,作为婆罗浮屠地区旅游活动的支持区。本研究的目的是预测吉里腾嘎流域的侵蚀,并为应用正确的水土保持技术来减少吉里腾嘎流域的侵蚀制定一个方案。利用水土评估工具(SWAT)模型进行侵蚀估算。结果表明:平均侵蚀量为30.7 t /ha/年,其中旱地侵蚀量最大;主要侵蚀危害等级分为极低、低和重三级。在台阶和山脊阶地结构中应用合适的SWC技术,有望将吉里吞加流域发生的侵蚀减少到极低的侵蚀危险等级(EHL)等级,达到总面积的60.4%,并消除严重的EHL等级。

Predicting Soil Erosion Using the Soil and Water Assessment Tool (SWAT) Model in Giritengah Catchment Area
. Giritengah catchment is 5 km to the southwest of Borobudur Temple and is an area that has been designated as a buffer zone that acts as a support zone for tourism activities in the Borobudur Area. The purpose of this study is to predict erosion in the Giritengah catchment and develop a scenario for the application of the right Soil and Water Conservation (SWC) techniques to reduce erosion in the Giritengah catchment. Erosion estimation is carried out using the Soil and Water Assessment Tool (SWAT) model. The results showed that the average amount of erosion is 30.7 tons/ha/year with the highest average erosion being on dry land use. The classification of predominant Erosion Hazard Levels is in the very low, low, and heavy classes. The application of the suitable SWC technique in the form of bench and ridge terrace’s structure is expected to be able to reduce erosion that occurs in the Giritengah catchment to very low Erosion Hazard Level (EHL) classes reaching 60.4% of the total area and eliminate heavy EHL classes.
