specific Embodiment approach 1

[0021] Specific embodiment one: the portable sample frame of this embodiment comprises two sets of unidirectional frames, four integral connectors; There are nine rope holes with equal distances; the two ends of the nine separation ropes 2 are bolted to the frame connecting pipe 1 through the rope holes respectively; the two frame connection pipes 1 in a set of one-way frames are parallelly expanded to nine separation ropes 2 are parallel to each other; the frame connecting pipe is a hard plastic hollow pipe, and the length of the frame connecting pipe is 1 meter.

[0022] The schematic diagram of the one-way frame structure in the portable sample frame of this embodiment is as follows: figure 1 shown.

[0023] Nine separation ropes of the present embodiment are assembled sequentially, and the two ends of the grid separation rope are in the Prussian knotting mode (such as figure 2 shown) bolted on the frame connecting pipe, the knot is required to fill the inward through ho...

specific Embodiment approach 2

[0025] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that both sets of unidirectional frames are deployed horizontally and stacked up and down. The separating ropes in the frame are perpendicular to each other, and the four frame connecting pipes are connected end to end to form a square, and the four corners of the square are fixed with integral connectors. Others are the same as the first embodiment.

[0026] In this embodiment, the frame connecting tube is inserted into the overall connector port to a depth of 14.9 mm, and the assembled structure schematic diagram is as follows image 3 As shown, 3 in the figure is an integral connector.

specific Embodiment approach 3

[0027] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the integral connector is a rigid plastic pipe with a 90-degree elbow. Others are the same as those in Embodiment 1 or 2.

[0028] In this embodiment, the overall connector has an outer diameter of 24.6 mm and an inner diameter of 20 mm; the overall connector has a length of 39.5 mm and a width of 39.5 mm.

[0029] Embodiment 3: This embodiment differs from Embodiment 1 in that the outer diameter of the frame connecting pipe is 20 mm. Others are the same as the first embodiment.

Abstract

The invention relates to a portable frame and application thereof, in particular to a portable frame and application thereof in investigation of wetland herbaceous vegetation. The problems that an existing wetland vegetation investigation device is complex in structure, inconvenient to carry and high in investigation error rate, influences the local environment and is high in single device cost are solved. The portable frame comprises two sets of one-way frames and four integral connectors. According to the application of the portable frame in investigation of wetland herbaceous vegetation, different investigation methods are adopted for different vegetation. The portable frame is high in operability, low in construction cost, convenient to use and suitable for various complex wetland environments and quadrat investigation precision levels, and the local ecological environment can be effectively protected during use.

Description

technical field [0001] The invention relates to a portable sample frame and its application. Background technique [0002] Wetland quadrat survey is a statistical behavior to obtain qualitative and quantitative information of plant communities, and it is an important method to identify wetland plant species, master community species composition, draw population life-form spectrum, and classify vegetation zonal composition characteristics. Scientific and applicable survey devices are the material basis for carrying out wetland scientific research, and efficient and accurate survey methods are the key link to improve the modern wetland ecosystem observation system. [0003] At present, several measuring devices such as measuring ropes, iron sample frames, and foldable supports are mainly used in quadrat surveys. The measuring rope is light in weight and easy to carry, but the process of laying out the sample quadrats requires the cooperation of multiple people, and the shape ...
