Description
Technical field
The utility model relates to a kind of runoff simulating device.
Background technology
The experimental simulation that runoff infiltrates always is an important research means in hydrology research.Infiltrate experimental simulation by runoff, can observe intuitively runoff at the motion process of soil surface and the moisture dynamic changing process in soil.In inland river basin in arid zone, it is not a disaster problem that flood overflows, and flood overflows the desert ecological recovery is had great significance.For flood overflow or ecological lock to control the produced runoff that overflows be also the hot issue of research at present.And at present pin Runoff Simulation device mainly for the rainfall runoff simulation of humid region or semiarid region, mainly in conjunction with artificial rain device, aggressivity runoff or pellicular water runoff that simulated rainfall produces.For the river of current Extreme Dry drought-hit area overflow or ecological lock to control the runoff applicability of overflowing poor.
The Extreme Dry drought-hit area is mainly Melting Glaciers: and snowmelt runoff, often causes flood, and generation is overflowed.Inland river basin in arid zone, except Natural Floods overflows, is also built ecological sluice gate is arranged at present, it is carried out to manual shift and overflow.For example current Tarimhe River, build 62 water-drawing gates, and Tarimhe River desert riverbank is manually discharged water, and irrigates deserta.The mode that discharges water of ecological lock is also the process of typically overflowing, and after river is crossed sluice gate, according to landform and underlying surface feature, in zone, overflows.The ability of its water supply is except relevant with gate design, diversion condition, also relevant with landform, soil and land utilization after ecological lock, with the size of flow discharges and time, has important associated especially.River leaves river course, and to form the motion process of its runoff after runoff be the problem that a lot of scholars are concerned about by ecological lock or by naturally overflowing.The growth and decline process of runoff is directly determining the scope of overflowing, and the area that the size of the scope of overflowing is recovered for vegetation ecological is producing important impact.Although large quantity research shows the recovery that flood overflows to vegetation and plays a part positive, but be not obviously that the revegetation that the flood of any type overflows to all districts of overflowing all has remarkable result, different flow and the frequencys of overflowing of overflowing are different on the impact of the conversion of motion of moisture.The root water uptake of well-known vegetation only occurs in soil root layer, if the micro unit of take is research object, the rainwash of crossing from surface flow so is invalid to this soil micro unit soil moisture, and the moisture that only enters to be seeped into soil could be absorbed by vegetation.
Current existing runoff simulating device, generally by rainer and directly water supply.Can't accurately control stable insulated stream.The deep percolation process produced for runoff also can't be measured.For having now at present, the river of Runoff Simulation device to the Extreme Dry drought-hit area overflows or ecological lock is controlled the poor problem of runoff applicability of overflowing, and the utility model designs a set of Runoff Simulation device, simulates the runoff infiltration process of extreme arid biogeographic zone.
