温州大学是一所地方综合性大学，办学历史可追溯到温州近代著名爱国爱乡人士黄溯初先生1933年创办的温州师范学校，文化底蕴深厚，有着优良的办学传统。
学校位于浙江省南部美丽的沿海城市温州。学校占地总面积2352亩，分茶山校区和学院路校区。茶山主校区位于温州高教园内，南眺罗山群峰，北蕴三垟湿地，山水灵秀与翰墨书香相得益彰，是莘莘学子修身治学的绝佳所在。
查明滑坡的运动特征及其影响因素，探讨滑坡的运动规律与内在机制，为区域防灾减灾工作提供理论借鉴。［方法］ 以泾阳南塬黄土滑坡为例，通过现场调查及槽探查明了滑坡的运动特征，采用统计学方法分析了滑坡的运动规律，在此基础上，探讨引起滑坡运动特征分异的“液化效应”。［结果］ 按照运动特征将泾阳南塬黄土滑坡划分为流滑型和滑动型两类，流滑型滑坡的滑距一般为坡高的4倍，滑动型滑坡的滑距约为坡高的2倍。1.50×1...
