Problems solved by technology

For the study of the pattern of herbaceous communities, the most important thing is the spatial position of the herb, that is, the coordinate value in space. With the help of modern instruments such as GPS, the collection of relatively large plant individual position information such as trees or shrubs can be completed, but it is limited by the GPS itself. Influenced by the signal accuracy, there will inevitably be a large error in the spatial position, which may be acceptable for arbors, but for the centimeter-level herbaceous spatial position, GPS and other instruments obviously cannot meet the requirements, and high-precision instruments themselves are more expensive

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] As shown in the figure, a measuring device for the species distribution pattern of a herbaceous plant community includes at least two module frames, the module frames include two frame sides arranged parallel to each other, and a plurality of parallel wires are equally arranged between the two frame sides , the silk wire is perpendicular to the frame edge, and a right-angle bend-through part is arranged at one end of the frame edge, and the right-angle bend-through parts of the two frame edges are arranged diagonally so that the two module frames can be assembled into a measurement frame; one of the module frames is a longitude frame, and one of the The module box is a latitude box, and the combination of a longitude box and a latitude box is a measurement box.

[0022] Further, it also includes a positioning frame, the smalles...

Abstract

The invention relates to a device and method for measuring the distribution pattern of herbaceous plant phytocoenosium species. The measuring device comprises at least two modular frames, wherein eachmodular frame comprises two parallelly arranged frame sides, multiple mutually parallel silk threads are arranged between the two frame sides in an equally divided mode, the silk threads are perpendicular to the frame sides, a right-angled bend part is arranged at one end of each frame side, and the right-angled bend parts on the two frame sides are arranged diagonally. One modular frame is a longitude frame, the other module frame is latitude frame, and the longitude frame and the latitude frame are combined to form a measurement frame. The device is simple in structure, easy to carry and low in manufacturing cost and can quickly measure the spatial distribution pattern of herb phytocoenosium.

Description

technical field [0001] The invention relates to a measuring device and a measuring method for the species distribution pattern of herbaceous plant communities. Background technique [0002] The herbaceous community is an important organic part of the forest ecosystem. It plays an important role in the material cycle and energy flow of the forest ecosystem. It is also the habitat and food source of many animals and microorganisms. Its species richness, distribution pattern, important value, etc. Research is an important part and hot spot of forest ecosystem research. [0003] Important research contents of forest communities or individual herbaceous communities include the spatial distribution and interspecific relationships of herbaceous plant species. Currently, there is a dearth of specialized devices available for surveying herbaceous communities during field surveys. There are measurement devices for herbaceous coverage and sub-coverage, but they are not sufficient for...
