摘　　要：腾冲县是云南省山洪灾害易发区,在分析研究该县以往山洪灾害灾情数据的基础上,提出了免疫进化算法优化的逻辑斯谛曲线山洪灾害灾情评价模型(IEA算法优化的LOG模型)。评价结果表明,该方法易于操作,克服了各单项灾情评估指标结果不相容的问题,能够有效解决复杂的非线型优化问题,可为县域山洪灾害的防灾减灾工作和工程治理提供决策参考。Mountain torrent disasters were prone to occurring in Tengchong County of Yunnan Province.Based on analyzing the data of past mountain torrent disasters in the county,the evaluation model for the Logistic curve-LOG of the Immune Evolutionary Algorithm was advanced.The evaluation results showed that the methods were apt to operating easily and solved the incompatible problems from monomial mensurated results of evaluation.It could be used to solve complex nonlinear optimization problems and provide decision-making gist for the jobs about disaster prevention and reduction and project management of mountain torrent disaster in the county.
