Description
Technical field
The invention belongs to Forestry Meteorology observation instrument technical field, particularly a kind of packaging type trunk stream determinator and assay method thereof.
Background technology
The change in time and space characteristic understanding rainfall each several part (as rainfall in woods, crown interception, trunk stream etc.) in forest ecosystem is often needed in research work in Forestry Meteorology, forest hydrology, water and soil conservation etc.Trunk stream, as the important component part of rainfall in forest, is one of emphasis in rainfall monitoring research always.
According to document and actual service condition, the method for measuring of current trunk stream and equipment are essentially two kinds.One is proofed sleeve spiral wrap trunk intercepting process, namely classification is carried out by the forest diameter of a cross-section of a tree trunk 1.3 meters above the ground, it is tree-like representational as normal wood with tree crown that each footpath level chooses 2 ~ 3 strains, forest apart from 1.3m place, ground, with the proofed sleeve spiral wound cut open to butt, be fixed on trunk with steel nail by proofed sleeve, fill up its gap with the waterproof material such as pitch, clay, semi-circular tube is bottom received in ground captation (as Plastic Drum or cement pit).Another kind is plastics bib method, and concrete thought is: winding plastic cloth on the smooth trunk processed, and the Polypropylence Sheet of smooth trunk upper end is wound around by elastic membrane more simultaneously, and fixes with iron wire, forms aquiclude; Then, by Polypropylence Sheet upper limb last volume parcel elastic membrane; Again, by Polypropylence Sheet lower edge upwards pocket rise and fix with iron wire; Finally, the water of plastics bib is guided to enter captation (as Plastic Drum or cement pit) by conduit.
Proofed sleeve spiral wrap trunk to collect the shortcoming of trunk stream is: 1) the intercepting path of determinator to trunk stream is long, makes proofed sleeve cause a large amount of mechanical damages with being fixedly connected of trunk to trunk; 2) gap of proofed sleeve and trunk is comparatively large, and it is quite difficult that its antiseep fills up process; 3) transporting of trunk stream is limited to narrow proofed sleeve passage, easily makes trunk stream excessive, causes the trunk stream collected to be less than actual value.
Plastics bib is wound around trunk: 1) at the closed place of aquiclude and trunk, one be difficult to guarantee trunk stream along trunk a small amount of under ooze, on the other hand because Polypropylence Sheet needs outer wraparound to wrap up in elastic membrane, cause to have one between this pervious bed and trunk can not the groove of draining, these aspects all will certainly expand the error of the method; 2) Polypropylence Sheet material used is poor, easily aging, fragile, and the mechanical support temporarily saved trunk stream is limited, can not reuse for a long time; 3) Polypropylence Sheet bib and branch, be connected indefinite between branch with aqueduct, lack scientific and precise; 4) be easy in installation process, cause Polypropylence Sheet to break or damage by the method for iron wire tighten Polypropylence Sheet, do not have the effect of due undertaking trunk stream; Use the method for iron wire tighten Polypropylence Sheet simultaneously, because iron wire is easy to get rusty, often cause the landing of plastics bib, the failure of an experiment.
The savings device of above two kinds of trunk streams is Plastic Drum or cement pit.Plastic bucket is easily aging, and need often upgrade, recycling rate of waterused is low, and is easy to suffer nature and artificial destruction; Meanwhile, the retention volume of plastic bucket is all fixing, and when meeting extra torrential rain, Plastic Drum is easy to fill and excessive, causes test and observes unsuccessfully.And cement pit is when doing water storage unit, because domatic leveling and cement pit construction not only can destroy ground vegetation, and time-consuming, effort, cost is high, and be very easily affected by the external environment with in the process of cement pit storage trunk stream, especially when cement pit is not added a cover, rainfall directly can enter into pond, thus causes trunk stream observational error.
Although above two kinds of trunk stream collection methods are different, but trunk flow assay methods is all identical, be namely all by conduit, the trunk flowing water collected is introduced in ground bucket or cement pit and carried out artificial observation (water collected in the equipment of being filled with water is measured the water yield by graduated cylinder, measuring cup etc.).Because general graduated cylinder or measuring cup are all less, so need, repeatedly by the water injection rate IR wetting system of the equipment of being filled with water, easily make water trickle down and then cause the inaccurate of experimental data; Measuring process is numerous and diverse simultaneously, easily causes error of omission or misremembers.
