| 英文摘要 | stratum, geological conformation, gradient of terrain and average maximal daily precipitation are selected as evaluation factor, weight of each factor is determined by AHP method, weighted average of factors is reckoned by overlay analysis function of GIS technique, and distribution map of degree of risk of county and district with debris flow repeatedly occurring in worst-hit area is obtained. The majority of debris flow ditches which broken out in rainy season of 2008 are located in area of high degree of risk, indicating that index system and method of evaluation offered in this paper are logical and feasible, the distribution map reflects distribution law of degree of risk of debris flow in disaster area after earthquake as a whole, and may be reference used for reconstruction after disaster in disaster area. |
