Abstract
The invention relates to a device for carrying out in-situ automatic control on the water level of a marsh wetland without external power, which comprises a low water level control pipe, a residual water collecting box, a high water level control pipe, a water supply bottle, a water supply tank, a conduit, a water control valve, a filter screen and a bracket. The high water level control is implemented in a mode that water is continuously and automatically supplied to the high water level control pipe by the water supply tank and the water supply bottle. The low water level control is implemented in a mode that the water in the low water level control pipe automatically flows into the residual water collecting box under the action of gravity. According to the invention, the water level of the marsh wetland can be automatically controlled in situ in the field in a small territorial scope under the condition without external power; the defect of large discrepancy between the indoor simulation environment and the real environment is overcome; meanwhile, the interference of other factors on an experimental result is eliminated; the device has a simple structure and is convenient to operate; and the manpower, material resources and cost which are invested in research can be greatly saved.
Description
Technical field
The invention belongs to Marsh Wetland greenhouse gases research field, particularly a kind of for the device without the rate of release of Marsh Wetland greenhouse gases on different hydraulic gradiants under additionaling power modeling effort in-situ condition.
Background technology
Marsh Wetland, due to its unique hydrologic condition, huge yield-power and organic reserves, makes it become a kind of important terrestrial ecosystems type.The Marsh Wetland greenhouse gases discharge a class key factor that is considered to affect whole world change, and by environment and ecological educational circles extensive concern.The water level condition is to affect the key factor that the Marsh Wetland greenhouse gases discharge.SEA LEVEL VARIATION is by changing the gas permeability of wetland soil, and then the soil profile oxidation-reduction potential is distributed and has conclusive impact, and finally affect the wetland soil microbial activity, thereby change the aerobic/anaerobic decomposition rate of wetland soil organic matter and as the rate of release of the greenhouse gases of organic matter decomposition product.
The mimic water-depth variation is a kind of important means in wetland greenhouse gases releasing research.Mimic water-depth changed the method that the research of wetland soil greenhouse gases release impact is generally adopted indoor soil-column cultivation and original position simulation in the past.Indoor cultural method, easy to operate, be easy to control the reaction conditions of culture systems, but have indoor condition of culture and the larger limitation of open-air true environment condition gap.Former bit emulating method, because environmental baseline and the open-air true environment condition of its culture systems are approximate, these class methods have been subject to more and more researchers' attention.The former bit emulating method of having reported at present is divided into two classes, and a class is to select different natural water level gradients to lay experimental provision in the scope of territory significantly.Although the disturbance less of these class methods to physical environment, but the deficiency of its maximum is, under the natural water level gradient, Marsh Wetland vegetation and soil matrix condition often varies widely, and therefore, these class methods can't be rejected the collaborative impact of other factors on SEA LEVEL VARIATION.Another kind of is to select same water level to bring the pedestrian into for controlling water level in more among a small circle.These class methods have been rejected the impact of other factors such as vegetation and soil matrix, but all adopted the additionaling power system on experiment control, require the driving arrangements such as configuration motor, pump, not only device is complicated, and need to be equipped with the concrete management personnel, greatly increased human and material resources and expense that research drops into.Therefore, simple in structure, easy operating, expense device cheap, automatically control the Marsh Wetland water level without the original position that is easy to realize of additionaling power are significant for the research work of wetland greenhouse gases.
