Problems solved by technology

The degree of dryness and humidity of the regional environment is usually measured by the degree of humidity in the region, and the change of regional precipitation is usually significantly related to the degree of humidity. Therefore, the degree of environmental humidity in a certain region is usually expressed by annual precipitation in the past, but the regional precipitation is used It cannot fully characterize the humidity of the environment in the area

Embodiment approach

[0106] As a specific embodiment of the method for measuring the degree of wetness in the area of ​​the present invention, its scheme is as follows:

[0107] From January to December 2016, the measurement personnel carried out the actual measurement in the Nanji Mountain Nature Reserve in the Poyang Lake area of ​​Jiangxi with four humidity index measuring instruments.

[0108] The humidity index measuring instrument collects local climate daily value data in real time, including air temperature, precipitation, sunshine hours, wind speed, and relative humidity, and then automatically calculates the net short-wave radiation and net long-wave radiation of the measurement area according to the formula (1). Radiation and the net radiation, combined with the dry and wet constant, the saturated water vapor pressure, the actual water vapor pressure and other parameters to calculate the daily value of the potential evapotranspiration in the measurement area, and store it together. The ...

Abstract

The present invention discloses a method and system for measuring a regional humidity degree. According to the method, firstly an environmental parameter of a measurement area is obtained, then a net radiation of the measurement area is calculated according to the environmental parameter, the potential evapotranspiration of the measurement area is calculated according to the environmental parameter and the net radiation, and finally a humidity index of the measurement area is calculated according to the potential evapotranspiration and the environmental parameter. According to the method and the system, the influences of parameters of air temperature, solar radiation, sunshine duration, wind speed, relative humidity and precipitation on the regional humidity degree are comprehensively considered, a calculation result can accurately characterize a regional environment humidity degree, and the reliability is high.

Description

technical field [0001] The invention relates to the technical field of environmental detection, in particular to a method and system for measuring the degree of humidity in a region. Background technique [0002] The report of the first working group of the fourth report of IPCC pointed out that the global temperature has generally increased, and the warming trend in the last 100 years (1906-2005) is 0.74℃ (IPCC, 2007). The problem has been brought to the attention. The dryness and wetness of the regional environment is usually measured by the wetness of the region, and the change of the regional precipitation is usually significantly related to the wetness. Therefore, the wetness of the environment in a certain region in the past is usually expressed by the annual precipitation, but the regional precipitation is used. It cannot fully characterize the wetness of the environment in this area. Therefore, how to provide a method that can accurately characterize the humidity d...
