基于GIS的中等比例尺地质灾害易发性评价

Evaluation on growth degree of the geological hazard based on GIS medium scale

通过采用信息量模型方法,以GIS为平台,针对工程区的地质灾害易发程度进行了研究分析,并最终得到了该区地质灾害易发程度信息,包括其地质灾害易发分区图及相关统计信息,评价结果与当地实际情况有较好的一致性。

Taking GIS for platform,the paper makes research analysis on the geological hazard in the project district by information model method,finally gets the growth degree information of the geological hazard in the district including the geological hazard growth degree zone map and the relevant statistic information,and the evaluation result is greatly consistent with the local practical situation.
