Description

Technical Field

[0001] The utility model belongs to the technical field of plant community sample plot arrangement, and in particular relates to a plant community sample plot arrangement device. Background Art

[0002] In ecology and vegetation science, traditional plot surveys are the basic method and main means to study forest plant populations, community characteristics and their dynamic changes. The shape of the plot is generally square or rectangular. However, in urban green forests, due to the influence of factors such as landscape planning, when investigating typical plant communities, the shape of the plot may not meet the requirements of square or rectangular, and the shape and size of the plot need to be changed. This process requires accurate demarcation of the boundaries of the plot and calculation of its area to ensure the accuracy and comparability of the data.

[0003] Traditional sample plot layout and area calculation methods mostly rely on manual measurement tools, such as tape measures, flower poles or ropes, to determine the boundaries of the sample plot and calculate its area. In addition, methods of visually measuring the vertex angle or calculating the vertex angle with the help of a compass are affected by factors such as human eye errors, signal strength, and battery power. There are large errors in the measurement of vertex angles and side length data, which affects the scientific nature of the survey data. These methods are not only time-consuming and labor-intensive, but also easily affected by the operator's skills and experience, leading to measurement errors.

[0004] In order to improve the accuracy and efficiency of the arrangement and area measurement of plant community plots, some technologies have tried to assist measurement and calculation through electronic devices and software algorithms in recent years. However, the equipment in the prior art is often complex in structure, inconvenient to operate, and the stability and reliability in harsh environments still need to be improved. In addition, the prior art has not yet provided a simple and accurate solution for how to directly calculate the area on the equipment and how to adapt to plots of different sizes and shapes. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a plant community sample plot arrangement device, which can simplify the arrangement and area measurement process of plant community sample plots, and improve the convenience of operation and the accuracy of measurement.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A plant community sample plot arrangement device comprises a marking cone, the top of the marking cone is connected to a support plate, the top of the support plate is plugged with a buckle, and the top of the buckle is connected to an angle measurement component;

[0008] The angle measuring assembly comprises a dial, a positioning seat is fixedly connected to the top center of the dial, a first pointer and a second pointer are sleeved on the positioning seat, and a level bubble is connected to the top of the positioning seat;

[0009] Adjacent buckle pieces are connected with measuring tapes.

[0010] Furthermore, a first through slot is formed through the side surface of the buckle member, and an arc-shaped buckle is fixedly connected to the side surface of the first through slot, and the shape of the arc-shaped buckle is set to be semicircular.

[0011] Furthermore, both ends of the buckle are fixedly connected with baffles, and the side of the baffle is fixedly connected with a plug-in column;

[0012] The top of the support plate is provided with a plug-in slot matched with the plug-in column.

[0013] Furthermore, a connecting thread is provided on the outer side of the top of the marking cone, and a connecting seat is fixedly connected to the bottom of the supporting plate.

[0014] Furthermore, the top of the dial is provided with scale lines distributed at equal intervals around its central axis.

[0015] Furthermore, a screw-on component is fixedly connected to the bottom of the vial, and a threaded column is fixedly connected to the bottom of the screw-on component.

[0016] Furthermore, a positioning buckle engaged with the arc-shaped buckle is fixedly connected to the side surface of one end of the tape measure, and second through grooves are formed through the side surface of the tape measure at equal intervals along its length direction.

[0017] A plant community sample quadrat area calculation system, the system comprising:

[0018] (1) Data input module, input the four side lengths and four vertex angles of the sample into the system;

[0019] (2) Sample shape identification module, which identifies the sample shape (square, rectangle, other quadrilateral) based on the input data;

[0020] (3) Data calculation module: if the sample shape is a square or rectangle, the sample area calculation formula is:

[0021] S = a × b, S is the sample area, a is the length of the quadrilateral, and b is the width of the quadrilateral;

[0022] If the sample plot is in the shape of another quadrilateral, measure the distance e between two vertices whose diagonal sum is greater than 180°, and calculate the sample plot area by referring to Heron's formula:

[0023]

[0024] S is the sample area, a and b are the adjacent sides of the quadrilateral, e is the diagonal length, P1 is = (a + b + e) ​​ / 2; c and d are the adjacent sides of the quadrilateral, P1 is = (c + d + e) ​​ / 2;

[0025] (4) Data output module, which visualizes the S value of the data calculation module.

[0026] Compared with the prior art, the beneficial effects of the utility model are:

[0027] First, the device provides an accurate and stable method to set and measure plant community plots through the coordinated work of the marking cone, support plate, buckle, angle measurement assembly and level bubble. In complex terrain, this design ensures the stability of the equipment and the accuracy of measurement. In particular, the addition of the level bubble ensures that the dial remains horizontal during operation, thereby reducing the measurement error caused by the tilt of the equipment.

[0028] Secondly, the design and use of the tape measure improves the traditional measurement method. The combination of the tape measure with the arc buckle and the positioning buckle not only speeds up the measurement process, but also improves the accuracy of the measurement. The installation and removal of the tape measure becomes quick and easy, allowing the operator to quickly adapt to the layout requirements of sample plots of different shapes and sizes. In addition, by combining the first pointer and the second pointer with the tape measure, the angle and side length of the sample plot can be accurately measured, which directly participates in the calculation of the area, greatly improving the accuracy and efficiency of the sample plot area measurement.

[0029] Finally, the design of the device targets a variety of problems that exist in traditional methods. For example, human visual errors, instability of the equipment in harsh environments, and complex operating procedures. Through automated and semi-automated designs, the impact of human operations is reduced, ensuring the scientificity and reliability of the data. In addition, the modular design of the system also allows for flexible use in different ecological environments and terrains, improving the versatility and practicality of the equipment. Through these design improvements, the system not only optimizes the operating process, but also improves the scientificity and efficiency of plant community sample plot surveys.
