Description

Technical Field

[0001] The present invention relates to the technical field of plant community construction, and in particular to a method for constructing a plant community based on plant functional traits and development. Background Art

[0002] In recent years, with the acceleration of economic globalization and the continuous growth of the world's population, human beings' excessive exploitation of ecosystems has caused drastic changes in the global environment. This has not only changed the process of biogeochemical transformation of the earth's ecosystem, but also led to global warming and changes in precipitation, which has also had an important impact on mountain ecosystems such as the Helan Mountains.

[0003] Therefore, in order to maintain the balanced ecosystem of the Helan Mountains and other mountains, the monitoring of plant communities on the Holland Mountains and the construction of plant communities have gradually been paid attention to.

[0004] As we all know, in the long process of evolution and development, plants have gradually formed many external morphological and internal physiological plant structures and physiological characteristics through interaction with the environment, namely plant attributes. Among them, a series of core plant attributes closely related to their growth, reproduction and survival ability are plant functional traits. With the deepening of understanding of plant functional traits, ecologists have gradually realized that research based on plant functional traits can better answer many key ecological issues. In addition to being affected by the habitat of the community and interspecific interactions, plant functional traits are also affected by the evolutionary history of the species. The functional trait phylogenetic niche conservation hypothesis believes that the trait differences between closely related species are smaller, and their niches are more similar, while the functional traits of distantly related species are more different. Functional traits are the manifestation of a certain functional aspect of plants, while phylogeny shows the overall differences between species, which is a combination of multiple traits. Lineages and functional traits cannot replace each other.

[0005] In order to effectively infer the different ecological processes that affect community construction, it is necessary to combine the key functional traits and the growth and development relationship of species, and use community phylogenetic information and quantifiable plant functional traits to jointly reveal the causes of community construction, which has become the key to plant community construction.

[0006] In the prior art, the construction of mountain plant communities is mostly carried out by field sampling by inspectors. The state of the plant community is constructed by testing samples at different locations. However, as time goes by, the state of the plant community after actual construction requires periodic field sampling by inspectors to update the state of the plant community. Not only does it require a large investment in human resources, making it difficult to construct the plant community, but it also has a slow update cycle and it is difficult to make an intuitive judgment on the impact of rapid periodic changes in the environment on plant growth. Summary of the invention

[0007] In view of the shortcomings of the prior art, the present invention provides a method for constructing a plant community based on plant functional traits and development, so as to solve the problem raised in the background technology that, when the prior art constructs a plant community system in mountainous areas, the system updates slowly and it is difficult to intuitively and quickly detect the functional traits and development of plants according to the rapid changes in the environment.

[0008] To achieve the above object, the present invention provides the following technical solution: a method for constructing a plant community based on plant functional traits and development, comprising the following steps:

[0009] a. Sample site selection: select multiple plant communities to be tested that are located within the vertical distribution area of ​​the Helan Mountains;

[0014] On the basis of the above scheme, in step a, based on the vertical differentiation of vegetation in Helan Mountain, typical plots were set up in Nansi and Beisi along the vegetation belts.

[0022] The transposition cylinder is penetrated and rotatably arranged on the power position adjustment box, and the positioning rod is penetrated and rotatably arranged on the transposition cylinder;

[0023] The transposition internal gear ring is arranged on one side of the transposition cylinder, and the transposition internal gear ring is located in the power position adjustment box;

[0024] The transposition rotating rod is rotatably arranged on the soil detection box;

[0025] The transposition gear is arranged on the transposition rotating rod, and the transposition gear is meshed with the transposition internal gear ring;

[0026] The transposition worm gear is arranged on the transposition rotating rod;

[0027] The transposition worm is rotatably arranged in the power adjustment box;

[0028] The transposition motor is installed on one side of the power position adjustment box, and the output end of the transposition motor is connected to one end of the transposition worm;

[0029] There are two transposition detection plates, which are arranged on the transposition tube, a detection cavity is formed between the two transposition detection plates, and the plant development detection mechanism is arranged between the two transposition detection plates.

[0030] Further on the basis of the above scheme, the plant development detection mechanism includes a height adjustment screw rod, a height adjustment motor, a height adjustment detection frame, a detection camera, a detection blade and a laser position finder;

[0031] The height adjustment screw rod is rotatably arranged between the two transposition detection plates, and a height adjustment ball nut assembly is threadedly connected to the height adjustment screw rod;

[0032] The height adjustment motor is mounted on the transposition detection plate at a side away from the power position adjustment box, and the output end of the height adjustment motor is connected to one end of the height adjustment screw rod;

[0033] The height adjustment detection frame is arranged on the height adjustment ball nut assembly, and the height adjustment detection frame is slidably arranged on the position change cylinder;

[0034] The detection camera is installed on a side of the height-adjusting detection frame away from the transposition cylinder;

[0035] The detection blade is arranged on a side of the height-adjusting detection frame away from the transposition cylinder, and the detection blade is located below the detection camera;

[0036] The laser position finder is arranged on a side of the height adjustment detection frame close to the position change cylinder. A position measurement plate is installed on the position change cylinder. The position measurement plate is matched with the laser position finder and is used to detect the position of the detection blade.

[0037] On the basis of the above-mentioned solution, a gas detector is further installed on the side of the soil detection box away from the transposed motor, which is used to detect the surrounding gas composition and gas temperature and humidity.

[0038] Compared with the prior art, the present invention provides a method for constructing a plant community based on plant functional traits and development, which has the following beneficial effects:

[0039] 1. In the present invention, when constructing a plant community system of plant functional traits and development, after selecting the location of the plant community, only one on-site detection is required. By detecting and analyzing the soil, gas and plants around the plant community, a difference map of plant functional traits and development between the same plants in different geographical locations can be constructed;

[0040] 2. After the plant community is constructed through multiple parameters, the present invention collects data and feedbacks about the plants around the location of the plant community through the plant community construction device. The soil detector can detect the amount of water in the soil and the change of soil composition according to the changes of the external environment. The gas detector can detect the temperature, humidity and gas composition of the gas around the plant community according to the changes of the environment. The data detected by the gas detector and the soil detector can be updated in the plant community system under the transmission of the remote signal receiver and the conversion of the central data conversion system.

[0041] 3. In the present invention, when the growth and development of independent plants are detected, the height adjustment motor is remotely started under the condition of remote detection and control of the detection camera, and the output end of the height adjustment motor drives the height adjustment screw to rotate, so that the height adjustment ball nut group moves on the height adjustment screw, and the movement of the height adjustment ball nut group drives the height adjustment detection frame to move, and the movement of the height adjustment detection frame simultaneously drives the detection blade, the laser position finder and the detection camera to perform longitudinal linear movement. When the production and development of plants are detected, the detection camera is used to preferentially observe the plants growing vertically upward, and the bottom end of the detection blade is brought into contact with the top of the plant. The position of the detection blade is initially positioned through the cooperation between the laser position finder and the positioning plate. According to the different plant species and the different growth rates, the corresponding development detection cycle is set. After the detection cycle is over, the position of the top of the plant is tested in the same way, and the position of the detection blade is re-positioned by the laser position finder. The distance between the measured position and the initial position is the height of the plant development.

[0042] 4. The present invention, when detecting the growth and development of clustered plants, because the plants themselves grow slowly and have many forked branches at the top, it is difficult to intuitively detect the development and growth status of the plants by detecting the height of the top growth of the plants. At this time, the transposition motor can be started, and the output end of the transposition motor drives the transposition worm to rotate, the rotation of the transposition worm drives the rotation of the transposition worm wheel, the rotation of the transposition worm wheel drives the rotation of the transposition rotating rod, the rotation of the transposition rotating rod drives the rotation of the transposition gear, the rotation of the transposition gear drives the rotation of the transposition inner gear ring, the rotation of the transposition inner gear ring drives the rotation of the transposition cylinder, and the rotation of the transposition cylinder drives the movement of the transposition detection plate. The position of the plant development detection mechanism can be moved laterally by the movement of the transposition detection plate, and the detection blade can cut the top of the plant by the movement of the plant development detection mechanism. Then, during the detection period, the growth of the new part of the top of the plant can be detected.

[0043] 5. The present invention, when detecting the growth and development of plants, can adjust the position of the detection blade through the transposition motor, and can also detect the growth and development of plants in different positions according to actual conditions. With the cooperation of multiple groups of plant development detection mechanisms, the production conditions of multiple plants can be synchronously detected at the same time. Through average calculation, the production and development of plants can be detected more accurately, making the data more accurate. In addition, through the remote detection of the plant development detection mechanism, there is no need for the staff to frequently climb mountains, which can greatly increase the update rate of the plant community system. According to the changes in the external environment, the impact of the external environment on plant development can be quickly judged, making it easier to maintain the entire Dutch Mountain ecosystem.

[0044] Therefore, this method of constructing plant communities based on plant functional traits and development can not only more intuitively judge the production status of plants according to environmental changes, but also quickly update the plant community system, greatly reducing the input of manual labor.

The transposition cylinder 8 passes through and is rotatably set on the power adjustment box 5. The positioning rod 6 passes through and is rotatably set on the transposition cylinder 8. The transposition inner gear ring 9 is set on one side of the transposition cylinder 8. The transposition inner gear ring 9 is located in the power adjustment box 5. The transposition rotating rod 10 is rotatably set on the soil detection box 3. The transposition gear 11 is set on the transposition rotating rod. On the rod 10, the transposition gear 11 is meshed with the transposition internal gear ring 9, the transposition worm wheel 12 is arranged on the transposition rotating rod 10, the transposition worm 13 is rotatably arranged in the power adjustment box 5, the transposition motor 14 is installed on one side of the power adjustment box 5, and the output end of the transposition motor 14 is connected to one end of the transposition worm 13. Two transposition detection plates 15 are provided, and the transposition detection plates 15 are arranged on the transposition cylinder 8. A detection cavity is formed between the two transposition detection plates 15, and the plant development detection mechanism 002 is arranged between the two transposition detection plates 15.

[0063] The plant development detection mechanism 002 includes a height adjustment screw rod 16, a height adjustment motor 18, a height adjustment detection frame 19, a detection camera 20, a detection blade 21 and a laser position detector 22. The height adjustment screw rod 16 is rotatably arranged between two transposition detection plates 15. A height adjustment ball nut group 17 is threadedly connected to the height adjustment screw rod 16. The height adjustment motor 18 is installed on the transposition detection plate 15 away from the side of the power position adjustment box 5. The output end of the height adjustment motor 18 is connected to one end of the height adjustment screw rod 16. The height adjustment detection frame 19 is arranged on the height adjustment screw rod 16. The height adjustment detection frame 19 is slidably arranged on the transposition cylinder 8, the detection camera 20 is installed on the side of the height adjustment detection frame 19 away from the transposition cylinder 8, the detection blade 21 is arranged on the side of the height adjustment detection frame 19 away from the transposition cylinder 8, the detection blade 21 is located below the detection camera 20, the laser position finder 22 is arranged on the side of the height adjustment detection frame 19 close to the transposition cylinder 8, and a positioning plate is installed on the transposition cylinder 8, the positioning plate is adapted to the laser position finder 22, and is used to detect the position of the detection blade 21.

[0064] In addition, a gas detector 23 is installed on the side of the soil detection box 3 away from the transposition motor 14 for detecting the surrounding gas composition and gas temperature and humidity.

[0065] Specifically, when constructing a plant community system of plant functional traits and development, after selecting the site for the plant community, only one on-site detection is required. By detecting and analyzing the soil, gas and plants around the plant community, a difference map of plant functional traits and development between plants in different geographical locations can be constructed. Based on the obtained parameters, the construction of the plant community system is an existing technology known to technicians in this field. The functional traits of the plant can be calculated by inputting the obtained parameters into the plant community construction system.

[0066] After the plant community is constructed through various parameters, when the plant community construction equipment is used to collect data feedback on the plants around the equipment location, the soil moisture and soil composition changes can be detected according to the changes in the external environment through the soil detector 4. The temperature, humidity and gas composition of the gas around the plant community can be detected according to the changes in the environment through the gas detector 23. The data detected by the gas detector 23 and the soil detector 4 can be updated for each corresponding parameter in the plant community system under the transmission of the remote signal receiver and the conversion of the central data conversion system.

[0067] It is supplemented that when the growth and development of independent plants are detected, when the detection camera 20 is remotely detected and controlled, the height adjustment motor 18 is remotely started, and the output end of the height adjustment motor 18 drives the height adjustment screw 16 to rotate, so that the height adjustment ball nut group 17 moves on the height adjustment screw 16, and the movement of the height adjustment ball nut group 17 will drive the height adjustment detection frame 19 to move, and the movement of the height adjustment detection frame 19 simultaneously drives the detection blade 21, the laser locator 22 and the detection camera 20 to perform longitudinal linear movement. When the production and development of plants are detected, the detection camera 20 is used to preferentially observe the plants growing vertically upward, and the bottom end of the detection blade 21 is brought into contact with the top of the plant. The position of the detection blade 21 is initially positioned through the cooperation between the laser locator 22 and the positioning plate. According to the different plant species and the different growth rates, the corresponding development detection cycle is set. After the detection cycle is over, the position of the top of the plant is tested in the same way, and the position of the detection blade 21 is re-positioned by the laser locator 22. The distance between the measured position and the initial position is the height of the plant development.

[0068] When detecting the growth and development of clustered plants, since the plants themselves grow slowly and have many forked branches at the top, it is difficult to intuitively detect the development and growth status of the plants by detecting the height of the growth of the top of the plants. At this time, the transposition motor 14 can be started, and the output end of the transposition motor 14 drives the transposition worm 13 to rotate, and the rotation of the transposition worm 13 drives the transposition worm wheel 12 to rotate, and the rotation of the transposition worm wheel 12 drives the transposition rotating rod 10 to rotate, and the rotation of the transposition rotating rod 10 drives the transposition gear 11 to rotate, and the rotation of the transposition gear 11 drives the transposition inner gear ring 9 to rotate, and the rotation of the transposition inner gear ring 9 drives the transposition cylinder 8 to rotate, and the rotation of the transposition cylinder 8 drives the transposition detection plate 15 to move. The position of the plant development detection mechanism 002 can be moved laterally by the movement of the transposition detection plate 15, and the detection blade 21 can cut the top of the plant by the movement of the plant development detection mechanism 002. Then, during the detection cycle, the growth of the new part of the top of the plant can be used to detect the development of the plant.

[0069] When detecting the growth and development of plants, the position of the detection blade 21 can be adjusted by the transposition motor 14, and the growth and development of plants in different positions can be detected according to actual conditions. With the cooperation of multiple groups of plant development detection mechanisms 002, the production conditions of multiple plants can be synchronously detected at the same time. Through average calculation, the production and development of plants can be detected more accurately, making the data more accurate. In addition, through the remote detection of the plant development detection mechanism 002, there is no need for staff to frequently climb mountains, which can greatly increase the update rate of the plant community system. According to changes in the external environment, the impact of the external environment on plant development can be quickly judged, making it easier to maintain the entire Dutch Mountain ecosystem.

[0070] It is additionally noted that if Figure 2 As shown, by setting up a solar panel 7, it is used to power the electrical components in the plant community construction equipment. For the remote control of each electrical component, it is necessary to install a remote signal receiver with a network signal on the soil detection box 3. By connecting the remote signal receiver with the central data conversion system, the detection results of the electrical components in the plant community construction equipment are received through the central data conversion system, and instructions are sent to each electrical component to achieve the purpose of remote control. The specific electrical connection method between the electrical components is not the main innovation of the present application, but is a prior art known to those skilled in the art. Finally, the received data is transmitted to the plant community system through the central data conversion system to update the data.

[0071] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
