Abstract

The invention discloses a combined grassland survey quadrat frame, and belongs to the field of sample collection. The combined grassland survey quadrat frame comprises a plurality of circular tubes, and connecting pieces arranged among the plurality of circular tubes, and a first connecting pipe and a second connecting pipe are respectively arranged at the end parts of two adjacent circular pipes;the first connecting pipe is rotationally connected with the second connecting pipe; a threaded baffle ring is arranged in the middle of the first connecting pipe; one end of the outer wall of the first connecting pipe is movably sleeved with a limiting sleeve; and a spring is arranged between the limiting sleeve and the first connecting pipe. According to the invention, the connecting pieces andthe circular tubes are mutually combined to assemble quadrat frames with different sizes, the working requirements of workers are met, the workers can conveniently transport the combined storage rackafter disassembly in a combined and detachable mode, the transportation convenience of the workers is improved, and the workers can conveniently fold and store the combined storage rack through rotation of the first connecting pipe and the second connecting pipe.

Description

technical field [0001] The invention relates to the technical field of sample collection, in particular to a combined grassland survey sample frame and a method for using the same. Background technique [0002] Field surveys of natural grasslands often use the four-degree-one-quantity survey method, which includes height, coverage, abundance, frequency, and biomass. When conducting surveys, it is necessary to carry many common tools, including measuring tapes, sample boxes, Tape measure, sample line, scissor steelyard or platform scale, etc. In particular, the sample square frame is an indispensable tool. The survey of four degrees and one measurement must be completed within one sample frame, and according to the needs of different surveys, generally a long-term field survey needs to bring different sizes of sample squares frame. [0003] Since there are not only many types of sample squares, but also many specifications, one sample frame cannot be unified, which brings a...
