Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] The purpose of the present invention is to use a simple and easy method, through the establishment and observation of snowmelt runoff in high mountainous areas and understanding the process and mechanism of snowmelt runoff in high altitude areas in arid and semi-arid areas, to understand the process of snowmelt, and to propose effective methods and methods for increasing snowmelt runoff. approach, so as to alleviate the contradiction between spring plowing water in the middle and lower reaches, and solve practical problems that urgently need to be solved in agricultural production.

Abstract

The invention discloses an arid and semiarid region alpine snowmelt runoff observation method. The observation method comprises the following steps: selecting a snowmelt runoff observation field; determining the construction place of the snowmelt runoff observation field; and constructing the snowmelt runoff observation field and a measuring cabin. According to the theories of the forest ecology and the forest hydrology, the generation and development rules of the snowmelt runoff are observed and researched, and the change rules of the snowmelt runoff under different meteorological conditions, different forest covers, different forest coverage rates and different artificial action modes are disclosed through observation, research and analysis, so the find-out of an effective way for increasing the flow of the snowmelt runoff, making up the flow of a river way in a dry season and alleviating the spring ploughing water conflicts along the middle and lower reaches is needed to solve an urgent practical problem in the current agricultural production.

Description

technical field [0001] The invention belongs to the technical field of snowmelt runoff observation in alpine areas, in particular to a method for observing snowmelt runoff in arid and semi-arid areas. Background technique [0002] "Forest Ecosystem Positioning Research Method" edited by the Science and Technology Department of the Ministry of Forestry and published by China Science and Technology Press, and "China Ecosystem Research Network Observation and Analysis Standard Method - Water Environment Elements Observation and Analysis" published by China Standard Press , the observation of slope runoff and the setting of artificial runoff field are introduced in detail. Regarding the hydrological process of forests, as well as the characteristics and laws of slope runoff under precipitation conditions, many domestic institutions have carried out research on forest hydrological processes with rich content, and have drawn many research conclusions with academic value. The rese...
