目的对我国常用的四种现场氡测量仪器RAD7、RTM2100、RTM1688和PQ2000的性能和测量结果进行比较。方法选择一个普通房间和高氡地下室进行了氡气含量的实地测量和比较。结果 PQ2000稳定性和可靠性最好,两个浓度的测量值与氡室参考值的R均为2%;RTM2100实测值波动较大,低水平测量时应注意延长测量时间;RAD7型连续测氡仪需要进行干燥处理,否则结果会偏低。结论四种连续测氡仪在不同环境的测量结果的可靠性均在有关标准的允许范围之内。

地形湿度指数可定量模拟流域内土壤水分的干湿状况,是静态土壤含水量的最常用指标,具有明确的物理意义。但是,由于DEM本身的结构特点,其提取的地形湿度指数具有尺度依赖性。本文主要探讨因DEM水平分辨率不同而导致的DEM栅格单元异质性,对地形湿度指数提取的影响。以厦门市地貌类型比较复杂的西源溪流域为实验区,使用1∶1万等高线生成的2.5m和20m分辨率DEM数据,分别提取地形湿度指数并计算栅格单元地形异
