Embodiment 1

[0023] see figure 1 , the present invention provides a technical solution: a method for measuring rainfall with a portable device for grassland ecological positioning and observation points, including a circular tray 13, a connecting screw 12, a main body rod 14 for installation, a rainfall collector 10, an anti-evaporation device 7, Rainfall storage 5, exhaust hose 8, filter screen 11, filter membrane 9, cylindrical shell 4 and base 2, install the main rod 14 with a length of 180cm, one section is buried in the ground with a depth of 30cm, and the other end is connected to the tray; the circular tray 13 connecting screws 12 are installed on the top of the main rod 14, and a portable rainfall measuring device is placed on the upper end of the circular tray 13; there are screws 1 on the bottom of the base and the top of the base is connected with the bottom of the cylindrical shell with a nut 3, and the exhaust hose is connected to the rainfall and the other end of the hose 8 i...

Embodiment 2

[0025] see figure 1 , the present invention provides a technical solution: a method for measuring rainfall with a portable device for grassland ecological positioning and observation points, the length of the main body rod 14 is installed, and the depth of a section buried in the ground is set according to the actual situation; in order to determine the collection of the rainfall collector Surface diameter, design artificial simulated rainfall experiments with different diameters of rain-collecting surfaces (4cm, 6cm, 8cm, 10cm, 12cm and 15cm), the simulated rainfall time is 5min, calculate the rainfall collection effect, and determine the optimal diameter of the rain-collecting surface. The test results found that the devices with rain-collecting surface diameters of 4cm, 6cm, 8cm, 10cm, 12cm and 15cm received 14.11, 28.00, 40.10, 58.33, 72.15 and 90.20g of rainfall in sequence. The equivalent unit cm diameter rainfall collection of different devices is 3.5283, 4.6667, 5.0124...

Abstract

The invention discloses a method for measuring rainfall by a portable device for a grassland ecological positioning observation point. The method comprises the steps of mounting the device, constructing the portable rainfall measuring device and acquiring rainfall data. The mounting device comprises a main body rod and a circular tray, one section of the main body rod is buried into soil by 30 cm, one end of the main body rod is connected with the tray through a screw, the tray is used for being connected with the portable device, and the portable device comprises a rainfall collector, an anti-evaporation device, a rainfall reservoir, an exhaust hose, a filter screen, a cylindrical shell and a base. When the method is used for measuring the rainfall, the portable rainfall measuring device is low in cost, small in grassland damage area, free of power supply equipment, simple to install and accurate in measured data, so that the problem that the rainfall data of a small area cannot be obtained due to sparse distribution of meteorological stations can be effectively solved; the method has a wide application prospect in grassland ecological positioning observation points with underdeveloped economy and poor natural environment.

Description

technical field [0001] The invention relates to the technical field of natural rainfall measurement, in particular to a method for measuring rainfall with a portable device at a grassland ecological positioning observation point. Background technique [0002] Accurate and rapid determination of rainfall is of great scientific significance to the growth of grassland vegetation and the stability of ecosystems. Under the background of ecological civilization construction, many scholars and scientific and technological personnel have carried out a large number of grassland ecological positioning and monitoring points to monitor the regional ecological status for a long time. However, my country's meteorological stations are mainly distributed at the city and county level, and the meteorological observation points are limited, which cannot meet the needs of more detailed regional research. The cost of setting up regional ecological positioning monitoring meteorological stations i...
