Benefits of technology

This technology helps researchers analyze how greenhouse gases are released from areas where they have been affected by droughts or other factors that affect their ability to absorb nutrients such as nitrogen fertilizers (N) into plants' roots through evapotranspiration processes. By measuring these changes over time, scientists may help predict future environmental risks associated with dry land fires caused by rain events.

Problems solved by technology

This patented technical problem addressed by this patents relates to studying how natural environments like rivers can help prevent damage caused from floods during times when they occur.

Embodiment Construction

[0033] The following uses the method of the present invention to take the three-ring flood detention area in the Sanjiang Plain as the research object, and carry out research on its hydrological function.

[0034] Through on-site surveys, data on hydrology, meteorology, agricultural production, land use, water conservancy projects, groundwater level changes, etc. have been collected in the past 50-60 years, combined with relevant engineering design and research literature of the river basin, and using remote sensing photographic data , various early topographic maps, and agricultural and water conservancy project planning and design drawings, etc., to obtain information and data on the underlying surface of the basin and the process of hydrological changes. By analyzing and calculating the ability of the Sanhuanpao flood detention area to regulate surface runoff and replenish groundwater, its water cycle regulation function in the watershed is analyzed.

Abstract

The invention discloses a hydrological research method of a flood detention area. The water circulation regulation function of the flood detention area in a watershed is analyzed by analyzing and calculating the regulation ability of the flood detention area to surface runoff and the replenishment ability to groundwater. Based on the data of hydrological stations, whether the variation of hydrological annual average runoff is increasing or decreasing is analyzed. The method analyzes whether there is land use change in catchment area and the effect of groundwater level change on wetland vegetation composition and structure, Through the analysis and calculation of flood regulation and storage function and groundwater replenishment amount, the influence on wetland vegetation, wetland soil andwetland aquatic ecosystem and groundwater replenishment function in flood detention area can be analyzed, thus playing an important role in the regulation of surface runoff and groundwater runoff inwatershed.
