The invention discloses a filter membrane clamping and collecting method for falling dust of a museum of an ancient ruined site. The method comprises the following steps: tailoring a filter membrane into a standard filter membrane with a diameter of 47mm; putting the filter membrane made of a quartz material into a muffle furnace to burn and removing residual impurities; putting into a constant-temperature and constant-humidity box and standing for over 24 hours; weighing, putting into a falling dust filter membrane collecting device with an inner diameter of 47mm; horizontally or vertically putting into a site region and carrying out falling dust collection; ending sampling and directly taking down the filter membrane; putting the filter membrane into the constant-temperature and constant-humidity chamber and keeping the consistent temperature and constant humidity for over 24 hours; and carrying out weighing and various chemical analysis. By virtue of the filter membrane clamping and collecting method for falling dust, the filter membrane is directly taken down to be subjected to weighing and chemical analysis, so that secondary pollution in falling dust collection is reduced; the analysis error in the falling dust quantity and the chemical components is reduced; the falling dust monitoring accuracy and normativity for the site environment are improved; and the interference to cultural relics and tourists is reduced to the minimal extent.
