Description

Farmland or runoff of sloping field water is monitoring and sampler automatically
Technical field
The utility model relates to the farmland or runoff of sloping field water is monitored and sampler automatically.
Background technology
The severe problem that migration is present China ecology, environment in the earth of soil erosion, pollution of area source, agricultural ground nutrient loss, pollutant and nutrient, agriculture and forestry faced, and runoff is the occasioner and the main carrier of these processes.Therefore, people attach great importance to the research of runoff and monitoring, only China from 1994 up to the present, the scientific paper of delivering on all kinds of natural science periodicals relevant with runoff reached 7087 pieces (obtaining by the retrieval to " CJFD (CJFD) "), wherein more than 330 piece of a piece of writing, run in depth and interflow surplus farmland and the slope runoff 600, these papers relate generally to ambits such as agricultural, forestry, environment, ecology, water and soil conservation, the hydrology, geology from nearly 500 scientific research institutions in the whole nation (containing university).As seen, the research to runoff is crucial.
The primary basis of research runoff is accurately to measure runoff, has the measuring technique of pressure, high water head, big flow, continuity runoff very ripe for river flow is this.Yet for no pressure, low water head, low discharge, intermittent runoff as agricultural run-off, slope runoff, soil permeability stream etc., what adopt basically at present is the water collecting basin method, promptly build a runoff pond (some has part flow arrangement) in the runoff exit, runoff water is collected in the pond, then the water in the calculated product pond.The plash method has apparent in view shortcoming: 1) can only measure the total amount of runoff, and can not observe the runoff generating process, be i.e. cumulative path flow, instantaneous through flow velocity and time relation curve; 2) can not collect the runoff water sample automatically, also just can't analyze the footpath flowable state of materials such as nutrient in the runoff water, agricultural chemicals, silt, i.e. cumulative flow vector, instantaneous loss speed and time relation curve can only analyze last total number of dropouts of these materials; When 3) run-off is big, spillover takes place easily, and under the underground water table condition with higher, the underground water phenomenon of osmosis takes place easily, excludes and plash can't permeate error with these; 4) can't eliminate influence of evaporation.The ultimate principle of plash method is that runoff water is accumulated, disposable then measurement, but as long as in the plash water is arranged, evaporation from water surface will take place, in the process that runoff water accumulates gradually, water surface evaporation also builds up.Particularly, because the randomness that runoff takes place is quite strong, back (particularly nocturnal runoff) takes place in runoff, runs into the situation that is difficult in time measure the plash water yield through regular meeting, and the evaporation from water surface error will be bigger; 5) plash belongs to the stationarity facility, and maneuverability is poor, is difficult to realize the multiple spot monitoring.Over the past two years, there are 3~4 pieces of academic articles to discuss available tipping bucket and accurately measure no pressure, low water head, low discharge, intermittent runoff, Chengdu soughing of the wind in the pines numeral science and technology have been developed CR2-L type double skip flowmeter (also having only model machine at present), can comparatively accurately measure no pressure, low water head, low discharge, intermittent runoff in 0.2mm~35mm scope, can analyze the runoff process, but, still can't analyze the runoff process of runoff water inclusions such as nutrient, agricultural chemicals, pollutant, silt in observation process because the runoff water sample can not be collected automatically.
