Description

Method for manufacturing comprehensive measuring device for forest rain penetration
Technical Field
The invention relates to the field of forest hydrology, in particular to a manufacturing method of a comprehensive measuring device for forest penetrating rain.
Background
Water is an important substance for the material circulation of the forest ecological system, and is also used as a main carrier for the material and energy circulation of the system and the forest ecological hydrologic process to participate in the regulation and control process of the forest ecological system. From the water balance, different plant species and forests composed of the plant species according to a certain space structure have different distribution characteristics on atmospheric precipitation. Therefore, the accurate observation and analysis of the distribution law of forests on rainfall has important significance for the analysis of understanding the regulation and distribution effects of forest preparation on water and the spatial patterns and processes generated by the regulation and distribution effects. The penetrating rain is the rain obtained by subtracting the canopy cut-off amount and trunk runoff from the rain outside the forest (also called total rainfall of the forest land), is an important component of forest rainfall redistribution, and the water conservation efficiency of the forest is greatly dependent on the penetrating rain actually entering the forest, so that accurate measurement of the penetrating rain of the forest is of great significance to the water balance research of a forest ecological system.
However, the collection and measurement work of penetrating rain with the canopy of the forest is mainly performed by other series of devices such as a collection tank and a collection box. The single-point rain collecting device provided by the prior CN102191789A and the simple-type forest canopy penetrating rain collecting and measuring device provided by the prior CN204989515U have small rain receiving area, so that the devices are required to be laid in batches with time and labor waste, and in addition, the devices are close to the ground and are easily interfered by animals such as snakes, rats, ants and the like, so that inaccurate measurement results are caused; a column-hanging type in-forest penetrating rain collector provided by CN202522717U has no filtering device, so that the in-forest penetrating rain collector is easily blocked by litters in the forest, is difficult to clean, and is potentially at risk of overflowing of rainwater caused by the fact that when the precipitation amount is large, the collecting port is not collected enough; if the under-forest penetrating rain collector proposed by CN201622356U is adopted as a bracket, the bracket is easily broken by sand and soil to cause difficult telescoping, meanwhile, the movable joint is easy to age, the phenomenon that the bracket slides down can occur, finally, the phenomenon that the precipitation is collected is incomplete is caused, a certain deviation can occur to a measuring result, meanwhile, the integral trend of the whole device is obvious, the integral disassembly and assembly are difficult, and the working efficiency of field staff is reduced.
