A framework for risk assessment on soil erosion by water using an integrated and systematic approach

摘要: A new approach for establishment of an analytical risk assessment model to evaluate the index soil erosion by water is proposed, in which remote sensing, GIS, hierarchy process (AHP), and modeling techniques are integrated through investigation a joining area that partially covers Shanxi province, Shaanxi Inner Mongolia Autonomous Region China. Based on field survey information analyses, pertinent factors this region assessed nine dominating identified. The considered include type, rainstorm intensity, landform accounting physiognomy ravine density, land slope, vegetation coverage, mining area, level conservation, type uses. GIS thematic layers degrees those constructed. weight each layer determined AHP technique. This then applied predicting development at typical scenario study area. brief discussion construction application presented. It demonstrated presented methodology practicable establishing mode interest where such as sensing data available. flowchart presenting general procedure implementation proposed also included.
