Simple and convenient under-forest vegetation rainfall runoff collecting and measuring device and mounting method

Abstract

The invention relates to a simple and convenient under-forest vegetation rainfall runoff collecting and measuring device and a mounting method. The simple and convenient under-forest vegetation rainfall runoff collecting and measuring device comprises a runoff collector and a runoff interception groove with an open top, an inner cavity of the runoff interception groove is divided into a first interception cavity and a second interception cavity through a vertical filter screen, the second interception cavity is communicated with the runoff collector through a water guide pipe, and the top of the second interception cavity is covered with a transverse filter screen. By arranging the vertical filter screen and the transverse filter screen, interference of foreign factors such as litters andinsects can be reduced, and the problem that rainwater overflows when the precipitation amount is large is solved; the water outlet of the rectangular runoff interception groove for collecting water is connected with the runoff collector for collecting water through a water guide pipe, so that the evaporation of the collected rainwater can be greatly reduced due to the factors; the rectangular runoff interception tank for collecting water and the runoff collector for collecting water are relatively independent, and sampling is convenient.

Description

technical field [0001] The invention relates to the technical field of runoff measurement, in particular to the measurement of rainfall runoff of understory vegetation, in particular to a simple understory vegetation rainfall runoff collection and measurement device and an installation method. Background technique [0002] Understory vegetation is a general term for forest understory shrubs, herbs, and vines, and is an important part of forest ecosystems. At present, there are relatively systematic studies on the indicator function, soil fertility maintenance and soil improvement of understory vegetation, but the research on its hydrological benefits, soil and water conservation and benefit evaluation needs to be further studied. Therefore, research on it is beneficial to guide the restoration of its understory vegetation, and has important theoretical and practical significance for soil and water conservation and ecological construction in difficult sites. At present, the ...

AI Technical Summary

Problems solved by technology

At present, the collection and measurement of rainfall runoff in understory vegetation mainly uses some devices such as collection bottles and collection boxes. Interference, when the precipitation is large, it is easy to cause the blockage of the collection port and make the rainwater overflow the collection box, which increases the collection error; second, the opening area of ​​the collection device is large, and when the rainfall is small, most of the rainwater is evaporated. The error of collecting rainwater is increased; the third is that the water collector of the collection device is not treated with anti-evaporation, which is prone to large errors due to evaporation; the fourth is that most of the collection devices are integrated, and the entire collection device needs to be moved when collecting precipitation.
