Description
Technical field
The utility model is related to a kind of forest precipitation station, especially one kind can accurately, total rainfall on real time measure woods,
The forest precipitation station of throughfall, water flow in the stem and interception, belongs to forest hydrology and forest ecology technical field.
Background technology
Rainfall falls on trees canopy, and a portion is retained by tree branches, and a part is fallen to the ground across canopy (wears
Saturating rain), a part reaches root (i.e. stem flow) by branch confluence through trunk.Trees act on the reallocation of rainfall, change
Rainfall reaches the Distribution Pattern on ground, is unevenly distributed undergrowth regeneration, generates the runoff mechanism from non-forest area different.
Undergrowth regeneration nonunf ormity certainly will cause the distribution of hayashishita soil moisture, nutrient, microorganism and lower vegetation to change.
Therefore, carry out total rainfall on accurate, real time measure woods, throughfall, water flow in the stem and canopy retention quantifier elimination, have
Important forest hydrology, ecological significance.
According to water balance, total rainfall should be equal to the sum of throughfall, water flow in the stem, interception three on woods.Mesh
Before, the rainfall of rainfall gauge measurement is laid on the ground usually outside forest to replace total rainfall on woods, but due to rainfall
Affected by wind in different height, this measurement, which obtains rainfall, can not be equal to total rainfall on woods.Water flow in the stem leads to
It is often to be flowed in water storage barrel or tipping-bucket rain-gauge obtain, but due to water storage by conduit again by installing cut-off groove on trunk
Ladle capacity is limited and cannot measure the process of stem flow, if measuring and pouring not in time in big rainfall, can lead
Cause overflow；Since the applicable raininess of tipping-bucket rain-gauge is generally less than 4mm/min, when more than this raininess, tipping bucket type rainfall
Meter cannot accurately measure water flow in the stem.At present, it is by laying multiple water collectors or V-arrangement catch basin (such as in hayashishita to penetrate rain
Design disclosed in the patent of CN205656323U) rainfall a little or in small area is first measured, then convert to wear by area
Saturating rain amount.Due to hayashishita penetrate rain distribution it is very uneven, this is just difficult to ensure that the accuracy of surveyed penetration.Canopy interception
Itself cannot directly measure to obtain, and can only measure to obtain on woods after total rainfall, throughfall and water flow in the stem, be calculated
Canopy interception.Due to measuring the method for former three at present there are error, certainly will leading to the calculating of interception, there is also larger
Error.Therefore, still lack the device that can while accurately measure total rainfall, throughfall and water flow in the stem on woods, limit at present
The development of forest hydrology and ecological study is made.

The tipping bucket meter 14 of one 1-3 liters/bucket.
Stem flow measuring device is flowed higher than cut-off groove 15 is installed on the trunk at girder 30-50cm by hose 13
Tipping bucket meter 16 to 0.4-0.6 liters/bucket measures water flow in the stem.As shown in Fig. 2, the installation needs of cut-off groove 15 are being ground
Around the EPE foam plate of 2-4cm thickness after flat 17 bark of trunk, foam ring 18 is formed, around the silicon of 2-4mm outside foam ring
Offset plate 19, the upper edge of silica gel plate are higher than foam ring 4-6cm.Foam ring 18 and silica gel plate 19 are fixed on trunk using band.
The hard tube 20 of a piece internal diameter 1-2cm is embedded in the seam crossing of foam ring 18, then the implantation glass glue on foam ring 18, by foam
Seam between ring 18 and bark, silica gel plate 19, hard tube 20 all blocks, and material is thus formed in the stem flow measuring device
Cut-off groove 15.Each tree sets the tipping bucket meter 16 of a 0.4-0.6 liters/bucket is independent to measure stem flow respectively.
Below using the contrast experiment in Nanjing Hydraulic Research Institute Chuzhou hydrological experiment base south Dawa County forest watershed as
Example, to embody the beneficial effects of the utility model.It is built in southern Dawa County's forest watershed according to the embodiment of the utility model
The forest precipitation station of one 4m × 8.5m, while the sample prescription of 25m × 25m is established in its vicinity, traditional side is used in sample prescription
Formula has laid 25 rain gauge measurements and has penetrated rain, 17 stem flow device monitoring stem flows.Table 1 to get out of the wood precipitation station and
The measurement result of 5 rainfalls during sample prescription August in 2017 12 days to September 16 days, from result：The tree that forest precipitation station measures
Scapus stream (mean value 3.3mm) is greater than the measuring and calculating value (mean value 2.1mm) of sample prescription.This is because hayashishita penetrates rain distribution very not
, bigger than normal (the rain mean value that penetrates of forest precipitation station and sample prescription is respectively 17.7mm to the rain that penetrates for leading to that a small amount of rain gauge measures
And 21.0mm), and then cause stem flow less than normal.It is big that canopy interception (mean value 5.0mm) is calculated by forest precipitation station
In the calculated value (mean value 2.9mm) of sample prescription.By comparing result it is found that the forest precipitation station that the utility model is announced can obtain ratio
Traditional measurement mode more accurately and reliably result.
1 forest precipitation station of table and sample prescription measure the comparing result of rainfall
Embodiment 2：
On the basis of embodiment 1, discounting for specifically measure each tree stem flow and both sides penetrate rain and catchment
The flow in face, as shown in figure 3, all stem flows can be flowed to the tipping bucket type flow of a 0.4-0.6 liters/bucket by hose
Meter 16, the stream that goes out of two buffer barrels 12 is pooled in the tipping bucket meter 14 of a 1-3 liters/bucket, can be saved into this way
This.
The specific technical solution being not limited to described in above-described embodiment of the utility model, it is all using equivalent replacement formed
Technical solution is the protection domain of the requires of the utility model.
