Debris flow susceptibility mapping(DFSM)has been reported in many studies,however,the irrational use of the same conditioning factor system for DFSM in regional-scale has not been thoroughly *** this paper,a region-partitioning method that is based on the topographic characteristics of watershed units was developed with the objective of establishing multiple conditioning factor systems for regional-scale ***,watershed units were selected as the mapping units and created throughout the entire research *** topographical factors,namely,elevation,slope,aspect and relative height difference,were selected as the basis for clustering watershed *** k-means clustering analysis was used to cluster the watershed units according to their topographic characteristics to partition the study area into several ***,the information gain ratio method was used to filter out superfluous factors to establish conditioning factor systems in each region for the subsequent debris flow susceptibility ***,a debris flow susceptibility map of the whole study area was acquired by merging the maps from all *** of Yongji County in Jilin Province,China was selected as a case study,and the analytical hierarchy process method was used to conduct a comparative analysis to evaluate the performance of the region-partitioning *** area under curve(AUC)values showed that the partitioning of the study area into two parts improved the prediction rate from 0.812 to *** results demonstrate that the region-partitioning method on the basis of topographic characteristics of watershed units can realize more reasonable regional-scale ***,the developed region-partitioning method can be used as a guide for regional-scale DFSM to mitigate the imminent debris flow risk.

学校文化是学校在自身长期发展过程中不断积累而成的文化成果,具体由物质文化、制度文化、精神文化等多个层面构成。良好的学校文化在促进学生个性化发展、教师专业化发展、学校特色化发展等方面都具有自身独特价值。然而,在当前学校文化建设实践中,存在内生性力量式微、主体参与性缺失及建设内容片面化的困境。为破解以上困境,本文提出精准定位、多方协同及多维联动的学校文化建设优化路径。

目的分析不同特征下适婚青年人群孕期保健相关知识得分的差异,探讨孕期保健相关知识得分的影响因素,为提高适婚青年孕期保健相关知识水平采取相应措施提供基础资料。方法于2014年12月—2015年2月,采用自编问卷调查表,运用随机抽样的方法,对前来阜南县妇幼保健院参加婚前医学检查的适婚青年男女进行孕期保健相关知识掌握程度的调查研究。结果共调查男性367人,平均年龄(24.96±3.14)岁;女性447人,平均年龄(24.30±3.27)岁。不同特征人群孕期保健相关知识得分中,本科及以上文化程度最高,为(6.96±2.29)分;3000~4000元月收入最高,为(6.00±2.09)分;有城镇职工医疗保障最高,为(6.53±2.16)分;处于孕期和有流产史的人群其得分最高,以上差异有统计学意义(P<0.05)。多元线性回归分析表明,影响孕期保健知识得分的主要因素为医疗保障、生育情况。结论阜南县参加免费婚前医学检查的人群孕期保健相关知识知晓得分较低。需要探索新型服务模式,提高适婚人群尤其是低文化程度人群、二孩备孕者的孕期保健相关知识水平。
