Abstract
The utility model belongs to the technical field of the design and manufacture of grassland resources and ecological investigation equipment, especially relate to a cover degree frame of survey grassland vegetation cover degree, including the big hollow connecting rods that are stick shape such as four, the bottom on the long limit of connecting rod is setting up the external screw thread, and the minor face afterbody is setting up the interior bolt that suits with the external screw thread, and the equipartition is setting up the engaging lug on the inboard of long limit of connecting rod and minor face, connect gradually four connecting rods and can form a cover degree frame that is the rectangle, be connected cotton rope and engaging lug, with forming a plurality of lattice in the cover degree frame. The utility model discloses beneficial effect: simple structure is equitable, determines fast, accurate, can also can dismantle into four alpin -stocks and use along with grass layer height regulating cover degree frame height, and it is also very convenient to carry.
Description
Technical field
The utility model belongs to the design and manufaction technical field of grassplot resource and ecology investigation apparatus, particularly relates to a kind of cover degree frame measuring grassland vegetation cover degree.
Background technology
In the work such as grassplot resource and ecology investigation, the acquisition of grassland vegetation cover degree quantitative data, in order to can accurately, fast fetching obtains the data message of the grassland vegetation cover degree in institute survey area, needs the vegetation cover degree measured in the sample area of regulation.At present, the assay method of grassland vegetation cover degree mainly still relies on the ocular estimate of professional and technical personnel, it is exactly the vegetation cover degree situation by virtue of experience measured by the eye in regulation sample prescription, this ocular estimate artificial subjective factor is too strong, specialty according to technician is different with ability can draw different data, accuracy and the credibility of data are lower, therefore design a kind of cover degree frame unifying to use and can draw more consistent and data information accurately.
Utility model content
The utility model, for existing Problems existing, provides novel a kind of cover degree frame measuring grassland vegetation cover degree, and make to measure vegetation cover degree standard unified, data are objective; Meanwhile, cover degree frame can be split and use as alpin-stock, accomplish one-object-many-purposes, alleviate the load of surveyor.
The purpose of this utility model is achieved through the following technical solutions: a kind of cover degree frame measuring grassland vegetation cover degree, comprise the hollow connecting link in stick-shaped that four grades are large, the bottom on the long limit of described connecting link arranges external thread, minor face afterbody arranges the inner bolt adapted with external thread, uniformly on the inner side of connecting link long limit and minor face arranges engaging lug; Four connecting links are connected successively and can form a rectangular cover degree frame, cotton rope is connected with engaging lug, forms several lattices by cover degree frame.
The utility model beneficial effect: simple and reasonable, measures fast, accurately, can regulate cover degree frame height with turf height, also detachably becomes four alpin-stocks to use, carries also very convenient.Can with demand Fast Measurement 1m

Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is main TV structure schematic diagram of the present utility model;
Accompanying drawing 2 is the main TV structure schematic diagram of the utility model connecting link.
Embodiment
Embodiment 1, a kind of cover degree frame measuring grassland vegetation cover degree, as shown in Figures 1 and 2, comprise the hollow connecting link 1 in stick-shaped that four grades are large, the bottom on the described long limit of connecting link 1 arranges external thread 5, minor face afterbody arranges the inner bolt 4 adapted with external thread 5, uniformly on the inner side of the long limit of connecting link 4 and minor face arranges engaging lug 2; Four connecting links 1 are connected successively and can form a rectangular cover degree frame, cotton rope 3 is connected with engaging lug 2, forms several lattices by cover degree frame.Connecting link 1 can be arranged in sharp cone distal bottom long limit, and bottom the minor face afterbody hollow position of connecting link 1 and long limit, sharp cone distal can form compact siro spinning technology.
In practice, can using connecting link as when participating in surveying work on foot, the alpenstock of use uses, after having arrived measured zone, connecting link is connected into cover degree frame, the region area then measured as required, can use with the lattice that cover degree frame is divided into needs to measure by cotton rope.
Claims (2)
1. one kind measures the cover degree frame of grassland vegetation cover degree, comprise the hollow connecting link (1) in stick-shaped that four grades are large, it is characterized in that: the bottom on described connecting link (1) long limit arranges external thread (5), minor face afterbody arranges the inner bolt (4) adapted with external thread (5), uniformly on the inner side of connecting link (4) long limit and minor face arranges engaging lug (2); Four connecting links (1) are connected successively and can form a rectangular cover degree frame, cotton rope (3) is connected with engaging lug (2), forms several lattices by cover degree frame.
2. a kind of cover degree frame measuring grassland vegetation cover degree according to claim 1, is characterized in that: can arrange in sharp cone distal bottom connecting link (1) long limit, and bottom the minor face afterbody hollow position of connecting link (1) and long limit, sharp cone distal can form compact siro spinning technology.
