Abstract

Transformation of land uses from several semi-arid agroecosystems in Indonesia: forest to settlement, dryland agriculture, and others had affected to soil erosion. This study was conducted to evaluate soil erosion at semi-arid Manikin Baki watershed, West Timor, Indonesia. USLE method was used to predict soil erosion supporting ArcGIS 10.3 software. The results showed that the highest soil erosion occurred at dryland farming (60.22% with total land cover 11% of total areas), while the smallest one went to the forest (0.20% with total land cover 42% of total areas). Another finding that soil erosion at Manikin Baki watershed was dominated by class I (12,251.77 Ha; 64.38% of total areas), while the smallest one was majored for class IV (1.59% of total areas).

利用GIS-USLE预测印尼西帝汶不同土地利用方式下的土壤侵蚀

印度尼西亚的土地利用从几个半干旱农业生态系统:森林到住区、旱地农业和其他方面的转变对土壤侵蚀产生了影响。本研究对印度尼西亚西帝汶曼尼金-巴基半干旱流域的土壤侵蚀进行了评价。采用USLE方法，支持ArcGIS 10.3软件进行土壤侵蚀预测。结果表明:旱地土壤侵蚀率最高(60.22%，占总面积的11%)，森林土壤侵蚀率最低(0.20%，占总面积的42%);Manikin - Baki流域土壤侵蚀以I类(12251.77 Ha)为主;占总面积的64.38%)，最小的是四年级专业(占总面积的1.59%)。
