Description

Technical Field

[0001] This invention relates to the field of plantation assessment technology, specifically to a plantation quality assessment system and method based on site conditions. Background Technology

[0002] Traditional plantation quality assessments often focus on current stand indicators (such as diameter at breast height, tree height, and stock volume), generally neglecting the impact of site conditions on the long-term development potential of stands. Site conditions, as a core natural environmental complex affecting tree growth, encompass key factors such as topography (slope, aspect, etc.), soil (type, humus thickness, etc.), climate (micro-regional temperature and humidity, light, etc.), and hydrology. Their quality directly determines the foundation and upper limit of the plantation's growth potential.

[0003] Existing site condition data collection mainly relies on manual field surveys, satellite remote sensing, or general-purpose sensors. Manual field surveys are time-consuming, costly, and highly subjective. Satellite remote sensing has limited spatial resolution, making it difficult to obtain ground parameters such as soil profiles and organic matter. General-purpose sensors (such as soil moisture meters and pH meters) are mostly single-point, discrete, and non-integrated, resulting in poor accuracy and comprehensiveness of site condition data collection, as well as low collection efficiency. No matter how advanced the subsequent quality assessment model is, it cannot provide reliable support for the quality assessment of plantations.

[0004] To address these issues, a site-condition-based plantation quality assessment system and method are provided. Summary of the Invention

[0005] The purpose of this invention is to provide a site-condition-based plantation quality assessment system and method, which solves the problem that existing site condition data collection relies on single-point, subjective sampling, leading to large deviations in assessment results.

[0016] As a further optimization of the present invention, the site condition acquisition device further includes a ground cover acquisition component, which is used to acquire ground cover information within the coverage area of ​​the standard measurement frame; the ground cover acquisition component includes a main cover, a camera and supplementary light fixedly installed on the top surface of the main cover, and a ground cover collection unit; the horizontal projection specifications of the main cover are completely matched with the standard measurement frame, and a flexible ring is provided at its bottom; the ground cover collection unit includes a suction hood installed inside the main cover, a storage cylinder fixedly installed on the top of the main cover, a suction pump for connecting the suction hood and the storage cylinder, and a translation module for driving the suction hood to move horizontally.

[0017] As a further optimization of the present invention, the ground cover collection component also includes a toggle unit for removing the cover to improve the shooting accuracy; the toggle unit includes elastic toggle rods symmetrically arranged on both sides of the suction hood.

[0018] As a further optimization of the present invention, the site condition acquisition device further includes a soil remediation component, which is used to repair the holes left after the probe and transparent sampling tube are inserted.

Detailed Implementation

[0041] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0042] Example 1

[0043] To address the issues that existing plantation quality assessment systems often rely on single indicators (such as diameter at breast height, tree height, and volume), neglecting the influence of site conditions, and that the collection of site condition data depends on single-point, subjective sampling, leading to significant biases in the assessment results, please refer to [link to relevant documentation]. Figures 1-2 The present invention provides a site-condition-based plantation quality assessment system, comprising:

[0044] Site condition data collection device, used to collect site condition parameters of artificial forests, including at least data on the thickness of the humus layer;

[0045] The data transmission module is used to transmit the collected data to a remote server or local storage device;

[0046] The quality assessment module is used to assess the quality of plantations based on the collected data.

[0047] The visualization module is used to display the evaluation results;

[0048] The site condition acquisition device includes a housing 1, a tension arm 2 fixed to the top of the housing 1, a lifting module 3 fixed to the end of the tension arm 2, a standard measuring frame 4 located at the movable end of the lifting module 3, and multiple probes 5 evenly distributed in a dot matrix within the standard measuring frame 4. The tension arm 2 can extend its working radius by folding or telescopically, and can be stored at the top of the housing 1 when not in operation. The standard measuring frame 4 can be a square of 0.25-1 square meters. The height of the probes 5 is adjustable so that the bottom end adapts to the ground surface. The lifting module 3 is used to simultaneously press all probes 5 into the soil to obtain data on the thickness of the humus layer by measuring the change in penetration resistance. The lower part of the housing 1 is equipped with a cleaning tank 101 for cleaning the residue on the surface of the probes 5. The cleaning tank 101 is equipped with a high-pressure spray head and a brush assembly for efficiently cleaning the soil, humus, and other residues attached to the surface of the probes 5 after penetration into the soil.

[0049] Site condition parameters of plantations, such as humus layer thickness data, are collected using a site condition acquisition device. Specifically, the container 1 is moved to the sampling point of the target plantation, the extension arm 2 is extended to a horizontal working position, and the standard measuring frame 4 is lowered by the lifting module 3. During this process, the bottom of each probe 5 adapts to the ground surface terrain to accommodate the undulations and ensures that the starting points of all probes 5 are consistent. Then, all probes 5 are pressed down synchronously by the lifting module 3 to penetrate the soil. The humus layer thickness data is obtained by observing the changes in penetration resistance. The humus layer is loose and soft, with low penetration resistance, while the mineral soil layer is compact, with a sharp increase in resistance. The data collected by the site condition acquisition device is then transmitted to a remote server or local storage device. Based on the collected data, the quality of the plantation is assessed, and the assessment results are displayed.

[0050] Furthermore, the probe 5 can also integrate sensors for detecting data such as soil moisture, soil temperature, and soil water content, which can be embedded in the probe 5 at the four corners of the standard measuring frame 4.

[0051] The standard measuring frame 4 has multiple first through holes 401 corresponding to the probe rods 5 one by one; each first through hole 401 forms a stepped mounting cavity along the axial direction, and an electromagnetic lock 501 for clamping or releasing the probe rods 5 is embedded in the lower part of the mounting cavity, and a pressure sensor 502 is fixedly installed in the upper part of the mounting cavity. The pressure sensor 502 and the electromagnetic lock 501 are coaxially arranged; the probe rods 5 pass through the center holes of the electromagnetic lock 501 and the pressure sensor 502 in sequence along the axial direction, and the pressure sensor 502 is physically separated from the probe rods 5; a counterweight 503 is fixedly installed on the top of the probe rods 5.

[0052] During the descent of the standard measuring frame 4 driven by the lifting module 3, the electromagnetic lock 501 is in the released state, and the bottom end of each probe 5 adapts to the terrain. Then, the electromagnetic lock 501 clamps the probe 5, and the lifting module 3 presses down the probe 5 to penetrate the soil. The electromagnetic lock 501 applies upward pressure to the pressure sensor 502, and the pressure sensor 502 collects pressure change data in real time. When the pressure changes abruptly, it is determined to be the boundary between the humus layer and the lower soil layer, thereby calculating the thickness of the humus layer.

[0053] like Figures 2-3 As shown, a soil sampling unit 6 is also provided above the standard measuring frame 4, which is used to rotate and extract a complete columnar sample to obtain a soil profile image. The soil sampling unit 6 includes an electric push rod 603, a motor 604 fixedly installed at the movable end of the electric push rod 603, an electromagnet 605 fixedly installed at the output end of the motor 604, and a two-dimensional slide rail platform 606 for driving the electric push rod 603 to move in a horizontal plane. The soil sampling unit 6 also includes a transparent sampling tube 601 and a magnetic docking seat 602 fixedly installed on the top of the transparent sampling tube 601. The magnetic docking seat 602 is adapted to the electromagnet 605. A second through hole 402 adapted to the transparent sampling tube 601 is opened on one side of each first through hole 401.

[0054] In specific use, before sampling, the transparent sampling tube 601 is inserted into the second through hole 402. The transparent sampling tube 601 fits tightly with the second through hole 402. Based on the humus layer thickness data, sampling is performed at any position within the frame as needed. The two-dimensional sliding platform 606 drives the electric push rod 603 to move to the target sampling position. The electromagnet 605 and the magnetic docking seat 602 magnetically connect and fix the transparent sampling tube 601. The electric push rod 603 presses down to drive the motor 604 to rotate, so that the transparent sampling tube 601 penetrates the soil to obtain a complete columnar sample. After lifting, a profile image is taken. The electromagnet 605 is de-energized to release the transparent sampling tube 601 and complete the sampling.

[0055] Example 2

[0056] Based on Example 1, in order to collect information on land cover, such as Figures 4-7As shown, the site condition acquisition device also includes a ground cover acquisition component. The ground cover acquisition component is used to acquire ground cover information within the coverage area of ​​the standard measurement frame 4 to identify herb / shrub cover and species, and to assist in judging soil exposure. The ground cover acquisition component includes a main cover 7, a camera 701 and a supplementary light 702 fixedly installed on the top surface inside the main cover 7, and a ground cover collection unit. The horizontal projection specifications of the main cover 7 are completely matched with the standard measurement frame 4, and a flexible ring 707 is provided at its bottom. The ground cover collection unit includes a suction hood 703 installed inside the main cover 7, a storage cylinder 705 fixedly installed on the top of the main cover 7, a suction pump 704 for connecting the suction hood 703 and the storage cylinder 705, and a translation module 706 for driving the suction hood 703 to move horizontally.

[0057] Before collecting humus layer thickness data through the standard measurement frame 4, surface cover information is first collected through the surface cover collection component. The surface cover collection component is moved to the original position of the standard measurement frame 4 through the cooperation of the slider 301 and the chute. The main cover 7 is driven to descend to a suitable height by the lifting module 3, and the camera 701 captures a panoramic image of the surface. Then, the suction hood 703 is moved by the translation module 706, and the elastic levers 708 on both sides simultaneously clear away obstructions such as fallen leaves and weeds, and the camera 701 captures the image again. If it is necessary to collect surface cover information, the main cover 7 is driven to descend by the lifting module 3 until the flexible ring 707 is fastened to the surface to form a closed space. The translation module 706 drives the suction hood 703 to move, the suction pump 704 is started, and the suction hood 703 sucks the surface cover (such as litter and herb samples) into the storage cylinder 705.

[0058] The ground cover acquisition component also includes a toggle unit for removing the cover to improve shooting accuracy; the toggle unit includes elastic toggle rods 708 symmetrically arranged on both sides of the suction cover 703, the end of the elastic toggle rod 708 is provided with an arc-shaped soft end, and the rod can elastically extend and retract in the vertical direction.

[0059] To avoid the holes left by probe 5 and transparent sampling tube 601 damaging the surrounding soil, causing soil structure disturbance, and hindering long-term dynamic monitoring, such as... Figure 4 , Figure 8As shown, the site condition acquisition device also includes a soil remediation component, which is used to repair the holes left after the probe 5 and the transparent sampling tube 601 are inserted. The soil remediation component includes a mounting plate 8, a liquid storage tank 803 fixedly installed on the top of the mounting plate 8, a spray pump 804 fixedly installed on one side of the liquid storage tank 803, a fixed spray gun 801, a movable spray gun 802, and a pipeline assembly 805 for connecting the spray pump 804 and each spray gun. The mounting plate 8 has perforations corresponding to the insertion positions of the probe 5 and the transparent sampling tube 601. The fixed spray gun 801 is fixedly inserted into the perforation of the corresponding probe 5, and the movable spray gun 802 is movably inserted into the perforation of the corresponding transparent sampling tube 601.

[0060] When using the soil remediation component, move it to the top of the standard measuring frame 4 and lock it in place. Adjust the position of the movable spray gun 802 and insert it above the soil sampling hole. The remediation liquid (such as a remediation liquid made of biodegradable plant gum and humic powder) in the storage tank 803 is pressurized by the spray pump 804 and then precisely injected into the hole left by the probe 5 and the transparent sampling tube 601 through the fixed spray gun 801 and the movable spray gun 802. After filling, the remediation is completed.

[0061] like Figure 9 As shown, a slider 301 is fixedly provided on the movable end of the lifting module 3. A positioning hole is provided on the slider 301. The sides of the standard measuring frame 4, the main cover 7, and the mounting plate 8 are all provided with sliding grooves that slide with the slider 301. All three are provided with positioning parts 9 that are inserted into the positioning holes. The standard measuring frame 4 and the main cover 7, and the standard measuring frame 4 and the mounting plate 8 are connected by hinges so that they can be folded and stored inside the box 1.

[0062] By sliding the slider 301 and the chute, the surface cover collection component and the soil remediation component can be switched sequentially to the top of the standard measurement frame 4, and then locked by the positioning component 9 to achieve precise alignment; after collection, the main cover 7 and the mounting plate 8 are folded by the hinge, the extension arm 2 is retracted, all components are stored in the box 1, and the probe 5 is cleaned by the cleaning tank 101.

[0063] Example 3

[0064] This invention also provides a method for assessing the quality of plantations based on site conditions, comprising the following steps:

[0065] S1. Collect site condition parameters of artificial forests using a site condition acquisition device, including at least the humus layer thickness data.

[0066] S2. The collected data is transmitted to a remote server or local storage device via the data transmission module;

[0067] S3. Conduct plantation quality assessment based on the collected data using the quality assessment module;

[0068] S4. Display the evaluation results through a visualization module;

[0069] When the site condition acquisition device collects data, the standard measurement frame 4 is moved above the target sampling point, and the bottom of each probe 5 is made to adapt to the ground surface terrain. Then, the lifting module 3 presses down all probes 5 into the soil in a synchronous manner, and the thickness data of the humus layer is obtained by the change of penetration resistance.

[0070] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
