Method for emergency water supplement of degraded wetland by clean energy

Abstract

The invention provides a method for emergency water replenishing of clean energy to a degraded wetland. The method specifically comprises the following steps: 1) determining a water replenishing watersource according to local hydrological conditions; 2) determining a water supplementing position according to local topographic conditions; 3) determining the minimum ecological water supplementing amount and the water supplementing time according to the wetland restoration target; 4) determining the power and specification of the wind power water elevator and the solar energy and wind energy integrated water pump according to the local wind energy and solar energy water resource gap; 5) installing water supplementing equipment on site, determining a water supplementing scheme according to the on-site detection data, and implementing accurate water supplementing; and 6) tracking, detecting and evaluating the water supplementing effect. According to the method, solar energy and wind energywater lifting equipment can be coupled for the water-deficient wetland with a surface water source or an underground water source nearby, and the optimal water supplementing time and water supplementing amount are determined according to seasonal differences of dominant vegetations and water birds in different stages for wetland moisture requirements, so that the purpose of accurately, ecologically and efficiently supplementing water is achieved.

Description

technical field [0001] The invention belongs to the technical field of ecological protection, and in particular relates to a method for emergency replenishment of degraded wetlands with clean energy. Background technique [0002] First, with urbanization and the increase in agricultural water demand, the water supply of most wetlands has gradually decreased, resulting in a reduction in wetland area and functional degradation. Understanding the water supply needs of different wetlands in different seasons and researching feasible water replenishment methods are the key factors in scientifically regulating water resources and maintaining the ecological health of wetlands. [0003] From the perspective of energy conservation and emission reduction, solar energy and wind energy have "zero" emissions and "zero" pollution, and have good environmental benefits. At present, a series of photovoltaic water conservancy products have been formed, such as photovoltaic water pumping syst...

AI Technical Summary

Problems solved by technology

At present, a series of photovoltaic water conservancy products have been formed, such as photovoltaic water pumping system (or called photovoltaic water pumping system), which are widely used in photovoltaic agriculture and forestry irrigation, photovoltaic desert control, photovoltaic grassland animal husbandry, photovoltaic domestic water, photovoltaic seawater desalination, photovoltaic urban waterscape and other fields , but the application in ecological protection is still rare

[0004] Secondly, the current wetland ecological replenishment generally adopts the extensive method of gravity flood irrigation, which requires a large amount of water and has low efficiency.

Use new water pipelines or fuel oil pumps to pump surface or groundwater nearby, or rely on the construction of water pipelines and canals for flood irrigation to achieve extensive flood irrigation ecological water replenishment, which is costly, inefficient, and environmentally unfriendly

[0005] Flood irrigation wastes water resources particularly seriously, requires more labor, and is likely to cause the groundwater table to rise, leading to soil salinization

In addition, flood irrigation is also likely to cause a lot of water in some places and insufficient water in some places.

[0006] Finally, there is currently no plan to use clean energy for wetland ecosystem water replenishment. For a case of using similar ideas in other fields, see "A Water Purification Equipment Based on Complementary Power Supply of Solar Energy and Wind Energy (CN201710553865)"; but this equipment It only uses clean energy to purify water quality, and has not been applied to ecological water replenishment

For example, the above patents "Ecological Water Supplement Scheduling Method and System for Small Urban Rivers (CN201410226487.5)" and "Lake Ecological Water Supplement Method Based on Wavelet Multi-scale Transformation (CN201010182787.X)" are only for water replenishment of lakes and rivers, and the use of clean energy Rehydration of wetlands is extremely rare, etc.
