Description

A kind of rubber Lin Linnei penetrates the rain measurement mechanism
Technical field
The utility model relates to meteorological utensil, in particular for penetrating the rainfall gatherer in the woods between high forest canopy and the scrub forest canopy, specifically is that a kind of rubber Lin Linnei penetrates the rain measurement mechanism.
Background technology
Forest water household balance is the dynamic process of a variation at all times, and the observed result of certain period can only be the basic situation of certain timing node, can not represent the situation of forest land reality fully.The space-time of each factor amount distributes, transmits, changes in the forest Water Cycle process, has fully manifested the different interface levels of forest ecosystem (as storey, ground cover layer, Soil Interface layer, border, basin etc.) moisture is had the different accent mechanism of holding.Therefore, continue the system ensemble observation that multi-faceted, multiple spot, multimode combine, could reflect the dynamic change mechanism that forest moisture space-time distributes, transmits, changes better, could propose rational forest management and administration measure for increasing forest moisture regulating power better, help rational utilization of water resources in artificial forest is managed, regulate the forest land water budget, protect and hold soil fertility.Provide scientific management activity and decision-making for improving forest yield-power and Ecosystem Service.
Forest penetrates rain (throughfall) and means " the rainfall after outer rainfall (claiming the forest land gross precipitation again) the deduction crown canopy interception of woods and the trunk runoff amount (the administrative standard LY/T1606 of People's Republic of China's forestry one 2003 " forest ecosystem location observation index systems ").
Penetrate rainfall by the raindrop that directly pass the crown canopy gap and through crown canopy and branches and leaves cut hold after the rainwater of drippage form, penetrating rainfall and trunk runoff amount, to have constituted effective rainfall in the woods (be actual rainfall in the woods after atmospheric precipitation is subjected to the storey crown_interception, also claim ground effective precipitation in the woods), effective rainfall participates in the formation of underground and rainwash in this woods, and directly affects the growth and decline variation of forest soil moisture.Characteristics of rainfall has appreciable impact to the spatial variations that penetrates rainfall, and research in the past thinks that sylvan life penetrates tangible straight line correlation relation is arranged between rainfall and the rainfall amount, foundation penetrate linear regression model (LRM) (Shi Deming etc., 1993 that the rain model also mostly is statistics; Liu Yijun, 2003; Shi Yuhu etc., 2004; Bao Wen etc., 2004), have research report forest to penetrate the correlativity of the power funtcional relationship of rainfall amount outside rainfall and the woods a little more than the correlativity (Liu Min etc., 2012) of linear regression recently.
Because forest plant spacing inequality, trees come in every shape and the difference of seeds branches and leaves, cause storey branches and leaves space distribution inhomogeneous, even also exist woods window or chearance to some extent, so difference is bigger everywhere to penetrate rainfall in the woods.In the real work of research forest water household balance, often need to observe penetrating rainfall.Measure penetrate in the forest woods rain method and technology have many, and constantly perfect.Mainly contain following several:
(1) numerical control sensor meter
This sensor is mainly by raingauge receiver, water storage room, float, inductor system, clock system, and signal processing circuit is formed.It is to utilize in the quantity of precipitation water storage room float to rise with rainfall to drive the induction pole system, makes sensor produce electric capacitance change, through be converted to displacement metering or numeral show quantity of precipitation and precipitation intensity.A lot of this numerical control sensor automatic gauges in the market, its shortcoming are, cost is expensive, safeguard complicated, fragile, field inspection under the incompatible long-term abominable natural conditions.

Weighing formula rain gage adopts the direct weighing rainfall of electronic scale, comprises a rain container, is provided with rain gage bucket in its lower end, and the rain gage bucket lower end is provided with weighing support and pressure-strain sensor, and the lower end of rain gage bucket is provided with drainpipe, is provided with automatically controlled draining valve at drainpipe.Sensor output weighing signal shows real-time rainfall amount and raininess after software systems are handled, when rainfall amount reached setting value in the rain gage bucket, draining valve automatic draining in rain gage bucket bottom had been arranged water and closed water valve automatically.Though this method accuracy height, continuous dataization is handled automatically, and because of antitheft relatively poor, reasons such as power consumption are difficult for locating for a long time in the open air being extensive use of.
(4) siphon rainfall recorder
Siphon rainfall recorder is made up of rain container, siphon, self-recording and four parts of shell.One float chamber is arranged under rain container, indoorly adorn a float and top self-recording nib links.Rainwater flows in the tube, and float rises thereupon, drives simultaneously on the recording pen on the float lever to lift, and draws a time dependent quantity of precipitation upcurve at the self-recording paper that rotates the clock tube.When the water level in the float chamber reached siphonal top, U trap was just discharged the rainwater in the float chamber rapidly at short notice and is finished a siphon.And so forth, record and measure rainfall intensity and the strong rainfall of whole period.Because of structural limitations, the capacity of float chamber can't be done too big, if meet the heavy showers process, siphon then frequently occurs, and record is interrupted too much, causes error in dipping; Friction, float straight-bar and float chamber top cover straight-bar between friction between siphon chamber and the float, recording pen and the pen shelves directly stained the friction that produces of getting rusty all can cause error in dipping; Greasy dirt is arranged and be connected not closely all can water clock (leak gas or leak) for U trap inwall and float chamber in addition, produces undesired record.
(5) multiple spot is laid standard rain gage bucket or the uncovered connected of water leg
Generally speaking, penetrate rainfall in the observation woods and adopt traditional multipoint method usually: several standard rain gage buckets are set in woods, or adopt the method for several water legs or water collecting basin.Water leg is normally made " U " shape groove that an end has rising pipe with iron sheet, and frame is gathered at support, whole collector easy-to-rust; The collector dimensions is more random, and observation data often lacks representativeness; Run into the not too convenient installation of forest land collector that landform is changeable, the gradient is big, damage " U " shape groove behind the bough windbreak easily by pressure.Self-evident, no matter adopt which kind of method, improve and penetrate the rainfall precision in the woods of actual measurement and just need to enlarge that to hold the rain area more big, more multi-measuring point namely is set, just must increase the workload of observation.
The rain measurement mechanism that penetrates described above respectively has advantage and disadvantage, the numerical control sensing, automatically weighing and siphoning installation safeguard loaded down with trivial details, involve great expense, fragile.Debugging is complicated, and be and consider open-air durable reliable that timeliness observation station needs that grow, elemental destructiveness, therefore, in conjunction with the open-air situation of forest and actual forest land feature, explore a kind of can be in the open air long-term location observation, practical simple, penetrate the rain measurement mechanism in the high woods of reliability and seem particularly necessary.
