Problems solved by technology

There are very few studies involving fog in China. The sampling method is only to place containers in the open air to receive the fog water. It does not take into account the interference of rainwater on sampling in the field environment, and cannot meet the requirements of avoiding water evaporation in the experiment. At the same time, the collection efficiency It is also relatively low; and there is a problem of high cost in the existing mist water collection instruments in foreign countries

Embodiment Construction

[0023] The device has been put into use in three sample plots in the alpine meadow of Balang Mountain in Sichuan Wolong Nature Reserve at an altitude of 3,720 meters, and the effect of collecting fog is good; in August 2005, a device was placed in the open alpine meadow facing the wind In the zone, fog water can be collected every time there is fog; during the experiment period, there were 12 days of fog, and 12 samples of fog water were collected, and the sample volume was between 20-70 ml. Its specific steps are as follows:

[0024] In the first step, assemble the instrument according to the previous instructions. Choose a nylon mesh with a mesh size between 0.5mm x 0.5mm - 1mm x 1mm.

[0025] The second step is to inspect the site and choose a better location to place the instrument. It is better to face the wind and open areas.

[0026] In the third step, place the sample collection bottle. If necessary, put a small amount of mineral oil in the bottle to reduce water ev...

Abstract

The invention belongs to the technical field of ecological engineering. A fog water collector suitable for collecting fog water samples in the field environment was designed. The mist collecting device is mainly composed of a rainwater retaining cover, two layers of mist absorbing nets, a mist collecting dish, a connecting handle and a supporting foot. It has high fog water collection efficiency, and can effectively remove the influence of vertical precipitation and water evaporation on fog water collection in the field environment, and provides a simple and efficient experimental device for carrying out research activities on fog water in the future.

Description

1. Technical field [0001] The invention belongs to the technical field of ecological engineering and relates to a simple method for manufacturing a mist collector. 2. Background technology [0002] Fog, as an important horizontal precipitation, has a unique position in the water input of ecosystems, especially coastal ecosystems and mountain ecosystems, and affects the water cycle, nutrient input, plant interspecific relationships and species diversity of ecosystems. sex. In addition, in some severely arid areas, such as Northwest my country and western South America, due to the scarcity of rain, fog water is an important water resource that can be used to alleviate or even eliminate local water shortages. [0003] However, for a long time, human beings' understanding of fog has remained at a superficial level, so that fog water is also called "occult precipitation". At the end of the 20th century, foreign countries began to pay more attention to the study of fog, and sinc...
