Method for measuring penetrating rainfalls of different canopy positions of arbor vegetation

The invention provides a method for measuring penetrating rainfalls of different canopy positions of arbor vegetation, and belongs to the technical field of forest hydrology test. The method comprisesthe following steps: equidistantly dividing the canopy of the arbor vegetation into n levels according to the canopy thickness of the arbor vegetation; placing rain measuring cylinders at different levels, wherein the placement manner of the rain measuring cylinders comprise: one rain measuring cylinder is placed with the trunk of the arbor vegetation as the center, and then the rain measuring cylinders are equidistantly placed toward N directions of the same horizontal plane from the outside to the inside; connecting the lower side of each rain measuring cylinder to a ground rain collectionbottle through a connecting pipe, collecting the rainfall in the ground rain collection bottles corresponding to the rain measuring cylinders of the same level, and using the obtained rainfall as thepenetrating rainfall of the
