Water storage amount time-space change and water amount balance monitoring method of peat swamp

Abstract

The invention discloses a water storage amount time-space change and water amount balance monitoring method of a peat swamp, and the method is mainly applied to the technical field of field measurement of the environment engineering, the plateau wetland and the peat swamp. The method mainly solves the problem that various groundwater hydrological elements in a peat layer of the plateau wetland cannot be subjected to field measurement for a long time. The main technical means is characterized in that through five types of point positions, arrangement sequence, arrangement method and monitoringdata of the five types of point positions, specifically, the five types of point positions are peat layer thickness detection points (1), underground water head observation points (2), sets of underground water change trend line observation points (3), self-recording water level gauge arrangement points (4) and penetration points (5), the field monitoring method which is adaptive to the water storage amount space-time change and water amount balance of the peat swamp is provided, and therefore all-directional monitoring of the change of the groundwater water storage capacity of the peat swampin a small watershed scale is realized.

Description

technical field [0001] The invention relates to the field measurement technology field of environmental engineering, plateau wetland and peat swamp. Background technique [0002] Peat swamps are important "reservoirs", and the water resources contained in them are the most critical elements for the survival of animals and plants in wetlands, and are also the main water supply for surrounding rivers. How much water is contained in small watershed-scale peat swamps has always been a hot issue in wetland science, but so far there is no answer that most scholars agree with. The main reasons for this are as follows: [0003] 1. The spatial distribution of peat bogs is discontinuous, and the thickness variation has no obvious rules. The usual thickness is 1-3m, but according to investigations, it can reach more than 10m in some places. Therefore, if the thickness of peat bogs is measured in a watershed, it must be measured on the spot, at least to ensure that it reaches the scal...

Problems solved by technology

[0005] 3. There are traces of human activities on some peat swamps. Specifically, there are artificial ditches, and the peat swamps have been drained and drained. This type of disturbance has a great impact on the water storage of peat swamps, regardless of time. Therefore, how to distinguish the impact of artificial ditches and natural ditches on the same peat swamp is also a difficult ...
