Description

Technical Field

[0001] The present invention relates to the field of ancient tree conservation, and in particular to a method for protecting and managing ancient and famous trees. Background Art

[0002] Ancient and famous trees are trees that have survived through human history and possess significant scientific, historical, or cultural value. According to the "Technical Regulations for the National Survey and Filing of Ancient and Famous Trees," ancient trees are defined as trees over 100 years old; famous trees are defined as trees planted by individuals who have had significant historical or social influence, or as trees of exceptional historical, cultural, or commemorative value. Ancient and famous trees are a scarce, non-renewable resource, a precious legacy of nature and history, a national treasure, and a vital vehicle for promoting and advancing ecological civilization. Ancient and famous trees are categorized as normal, weakened, endangered, or dead based on their growth potential. The National Afforestation Committee's second survey of ancient and famous trees revealed a total of 1,037,400 ancient trees in normal growth, 157,700 in weakened growth, and 26,300 in endangered status. Trees in weakened and endangered status account for 15.1% of the country's scattered ancient and famous trees. The inadequacy and lag in health monitoring methods for ancient and famous trees, as well as the inadequacy of maintenance and rejuvenation measures, are the fundamental reasons for the weakening growth and even endangered and dead growth of ancient and famous trees.

[0003] Currently, the protection of ancient and famous trees mainly relies on information technology to complete the survey of ancient and famous tree resources and record information such as the type, age, longitude and latitude, and growth status of the ancient and famous trees. On this basis, video surveillance is introduced to provide maintenance personnel with a means to remotely view the growth status of ancient and famous trees; a navigation module is introduced to guide inspectors to the location of the trees; an early warning module is introduced to generate early warning information based on the inspectors' inspection records; bird-repelling facilities are deployed to drive away flocks of birds; voice alarm facilities are deployed to issue voice warnings when monitoring detects human damage; and a maintenance log module is introduced to record manual maintenance information. However, the shortcomings of the existing technology are also very obvious. The main ones are that the monitoring methods are relatively simple and fail to cover the ancient and famous tree health monitoring indicator system; the maintenance plan is not targeted enough and is not established based on the health characteristics of ancient and famous trees; the maintenance implementation does not form a closed-loop task, which poses a risk of loopholes in the protection of ancient and famous trees. Therefore, based on the above problems, a protection and management method for ancient and famous trees is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a method for the protection and management of ancient and famous trees, which can comprehensively evaluate the health of ancient trees, formulate different maintenance plans for different health levels, and form a complete task closed loop from data acquisition to maintenance completion to solve existing technical defects and unattainable technical requirements.

[0005] To achieve the above object, the present invention provides the following technical solution: a method for protecting and managing ancient and famous trees, comprising the following steps:

[0006] 1. Establish a health evaluation model for ancient and famous trees based on existing health evaluation standards for ancient and famous trees;

[0007] 2. Obtain information on the status of ancient and famous trees from multiple angles;

[0008] 3. Analyze the information obtained in step 2;

[0009] 4. Determine the classification of each monitoring indicator for the protection of ancient and famous trees;

[0010] 5. Based on the classification of the ancient and famous tree protection monitoring indicators in step 4, use the analysis data in step 3 to calculate the health status of the ancient and famous trees;

[0011] 6. Based on the health calculation results in step 5, evaluate the health level of ancient and famous trees and describe their health status characteristics;

[0012] 7. Based on the health assessment information of ancient and famous trees in step 6, establish a targeted ancient and famous tree maintenance plan;

[0013] 8. Implement the ancient and famous tree maintenance plan established in step 7 and conduct closed-loop task management.

[0014] In this application, in step one, the existing standards for evaluating the health of ancient trees and famous trees are based on the standards for evaluating the health of ancient trees and famous trees in the location of the target ancient trees and famous trees, including but not limited to the "Technical Regulations for Rapid Diagnosis of the Health of Ancient Trees and Famous Trees in Beijing" (DB11T 1113-2014), the "Technical Regulations for Rapid Diagnosis of the Health of Ancient Trees and Famous Trees in Zhejiang Province" and the "Technical Regulations for Diagnosis of the Health of Urban Ancient Trees and Famous Trees" based on the local standards for engineering construction in Fujian Province, etc., which can be understood as collecting the corresponding information of ancient trees and famous trees according to the relevant standards of the region where the ancient trees and famous trees to be protected are located.

[0015] Preferably, the specific content of step 1 is:

[0016] 1.1. Based on the region where the ancient and famous trees are located, obtain the various indicators used to judge the health status of the ancient and famous trees in the existing ancient and famous tree health diagnostic standards in the region;

[0017] 1.2. Determine the information of the ancient and famous trees that need to be tested based on the indicators in step 1.1.

[0018] Preferably, in the step 2, obtaining the status information of ancient trees and famous trees from various angles includes: obtaining spectral information of the surface of ancient trees and famous trees, obtaining image information of different parts of the surface of ancient trees and famous trees, obtaining stress wave information of the internal decay status of the trunks of ancient trees and famous trees, obtaining stem flow information of the trunks of ancient trees and famous trees, obtaining distribution information of the root systems of ancient trees and famous trees, obtaining meteorological data of the surrounding environment of ancient trees and famous trees, obtaining soil data at different depths under the crown of ancient trees and famous trees, and obtaining information on diseases and insect pests of ancient trees and famous trees and their surrounding environment, wherein obtaining the stem flow information of the trunks of ancient trees and famous trees is not abandoned according to the standards of the area where the ancient trees are located.

[0019] In the present application, it is necessary to further explain that the information acquisition of other relevant items related to the health evaluation of ancient and famous trees in the present application (items corresponding to single indicators, various items used to evaluate the health) is based on the standards of the area where the ancient and famous trees are located, but the acquisition of the stemflow information of the trunk is required regardless of the location of the ancient and famous trees. That is, it can be understood that in the present application, no matter what kind of ancient and famous trees are tested for health, it is necessary to obtain the stemflow information of the trunk of the ancient and famous trees, and if the health evaluation standards of the area where the ancient and famous trees are located involve the calculation of stemflow information, the obtained stemflow information participates in the calculation of steps four and five, otherwise, the obtained stemflow information of the trunk of the ancient and famous trees only participates in the analysis of step three and the description of the health status in step six.

[0020] Preferably, the specific information to be obtained in step 2 is:

[0021] The spectral information includes spectral information of the crowns of ancient and famous trees;

[0022] The image information of different parts of the surface of the ancient and famous trees includes image information of the crown, the ground environment under the crown, the root system under the crown, the trunk and branches;

[0023] The root distribution information of the ancient and famous trees includes the root distribution depth and horizontal amplitude;

[0024] The meteorological information includes temperature, humidity, rainfall, wind speed and direction around ancient and famous trees;

[0025] The soil data includes soil temperature, humidity, pH, inorganic salt content, etc.;

[0026] Among them, the information collection cycle for the tree crown is once a day, the information collection cycle for the branches is once a month, the information collection cycle for the trunk is once a month or once every six months, the information collection cycle for the root system is once every six months, the information collection cycle for the tree growth environment is once a day or once every six months, and the collection cycle for tree disease and pest information is once a day.

[0027] In this application, it needs to be explained that the image information of different parts of the surface of ancient trees and famous trees also includes information on the roots of the ancient trees and the vegetation around them. Although the above description is the information of different parts of the surface of the ancient trees, the roots of some ancient trees will be exposed on the bottom surface, so in this case, it is also necessary to collect information on the exposed parts of the roots, so that the vegetation information around the ancient trees can be collected at the same time.

[0028] Preferably, in step three, the specific content of the information analysis is:

[0029] Analyze whether the leaf surface is normal and the chlorophyll content of the leaves based on spectral information;

[0030] Analyze trunk damage, trunk tilt, and ground conditions based on image information from different parts of the ancient and famous trees;

[0031] Analyze the internal decay of ancient and famous trees based on the stress wave information of the internal decay of the trunk;

[0032] Analyze the growth status of ancient and famous trees based on the stem flow information of the trunk;

[0033] Analyze root distribution and root damage based on relevant root information;

[0034] Analyze the temperature, humidity, rainfall, wind speed and direction around ancient and famous trees based on meteorological data;

[0035] Analyze the temperature, humidity, pH, inorganic salt content, etc. of the soil at different depths under ancient and famous trees based on soil data;

[0036] Based on the pest and disease information, analyze the types of pests and diseases of ancient and famous trees, the damage symptoms, insect population density, etc.

[0037] Preferably, in step 4, the monitoring indicators for the protection of ancient and famous trees include six dimensions: leaves, branches, trunks, roots, growth environment, and pests and diseases.

[0038] It is necessary to explain in this application that the above indicators include at least the following:

[0039] Leaves: Indicators related to leaves include normal leaf rate and chlorophyll content.

[0040] Branches: Indicators related to branches include the degree of treetop damage and the amount of new shoot growth.

[0041] Trunk: Indicators related to the trunk include trunk inclination, degree of trunk damage, degree of bark loss, trunk internal rot, and trunk stem flow.

[0042] Root system: Indicators related to the root system include root distribution and the degree of loss of exposed roots.

[0043] Growth environment: Indicators related to the growth environment include the degree of hardening under the crown, soil coverage, soil pH, soil temperature, soil moisture, and air temperature.

[0044] Preferably, the specific contents of step five include:

[0045] 5.1. Calculate the indicators in step 4 based on the ancient and famous tree health evaluation model: First, determine the indicator's classification based on the measured value. Then, based on the score range of the classification, use the interpolation method to calculate the score of the indicator. The calculation method is as follows:

[0046] Ni=score Min +(value-value Min )*(score Max -score Min ) / (value Max -value Min )

[0047] Among them, i represents the i-th indicator, Ni is the score of the indicator (single indicator score), score Min Indicates the lowest value of the indicator grading score range, score Max Indicates the highest value of the indicator grading score interval, value indicates the indicator measurement value, value Min Indicates the lowest value of the indicator classification interval, value Max Indicates the highest value of the indicator classification range.

[0048] The above content needs to refer to the existing health diagnosis standards for ancient and famous trees, including relevant documents issued by various provinces and cities regarding health diagnosis standards for ancient and famous trees, including but not limited to the following:

[0049] The "Technical Regulations for Rapid Health Diagnosis of Ancient and Famous Trees in Beijing" (DB11T 1113-2014) evaluates the health of ancient and famous trees from four dimensions: leaves, branches, trunks, and roots. Specifically, it includes seven indicators: normal leaf rate (%), dead and broken branch ratio (%), annual growth of new shoots (deciduous species) (cm), annual growth of new shoots (evergreen species) (cm), trunk inclination (°), degree of trunk damage (%), and degree of damage to exposed roots (%). Furthermore, the monitoring value of each indicator corresponds to the indicator grade in the model. Furthermore, a weight value is set for each indicator to evaluate the impact of different indicators on health.

[0050] According to the "Technical Regulations for Health Diagnosis of Ancient and Famous Trees in Zhejiang Province", the health of ancient and famous trees is evaluated from six dimensions: leaves, branches, trunks, roots, growth environment, and pests and diseases. Specifically, 11 indicators are used to evaluate the health of ancient and famous trees, including the normal leaf rate (%), the degree of branch (treetop) damage (%), the degree of trunk (first-level branch) damage (%), the inclination of the main trunk (°), the degree of bark damage (%), the internal decay of the trunk (%), the degree of root damage (%), the degree of hardening under the crown (%), the degree of soil cover (fill) (%), soil pH, and the degree of pest and disease damage. Furthermore, the monitoring value of each indicator corresponds to the indicator grade in the model. Furthermore, a weight value is set for each indicator to evaluate the impact of different indicators on health.

[0051] According to the Fujian Provincial Engineering Construction Local Standard, the "Technical Regulations for Health Diagnosis of Ancient and Famous Trees in Cities" assesses the health of ancient and famous trees based on three categories: tree condition, environmental factors caused by urban construction, and pests; seven primary indicators, including leaves, branches, trunks, harmful substances in the soil, stress factors such as buildings or pipelines, parasitic plants, and climbing plants; and 13 secondary indicators, including abnormal leaf rate, leaf area index, relative chlorophyll content, proportion of dead and broken branches, trunk hollow volume ratio, bark damage area ratio, soil pH, soil heavy metals, soil toxic organic matter, underground effective space ratio, aboveground effective space ratio, severity of parasitic plant threats, and degree of entanglement and coverage of climbing plants. Furthermore, the monitoring value of each indicator corresponds to the indicator classification in the model. Furthermore, a weight value is assigned to each indicator to evaluate its impact on health.

[0052] Preferably, in step 5, the calculation content of health degree is:

[0053] 5.2. Calculation of comprehensive health index score:

[0054] Among them, S is the comprehensive health index score of ancient and famous trees, with one decimal place retained, Ni is the score of the i-th level indicator, with one decimal place retained, Ai is the weight corresponding to the i-th level indicator, and n is the number of level indicators.

[0055] In this application, it needs to be further explained that the "grade indicators" in the above content usually refer to secondary indicators, but different regions have different indicator grading standards, and some regions do not grade indicators, so this application does not limit the specific grading situation.

[0056] In addition, in this application, since the health grades of ancient trees and famous trees in different regions correspond to different scoring systems (ten-point system and hundred-point system), this application adopts the ten-point system when calculating the scores of individual indicators and the comprehensive health index. One decimal place is retained when calculating the scores of individual indicators, and the number of decimal places retained when calculating the comprehensive health index is determined according to the standards of the region where the ancient trees and famous trees are located. That is, when calculating the comprehensive health index score, if the corresponding standard grade evaluation adopts the ten-point system, then this application retains one decimal place. If the corresponding standard grade evaluation adopts the hundred-point system when calculating the comprehensive health index score, then this application retains two decimal places. After calculation, the comprehensive health index score calculated in this application is expanded ten times to obtain a score that is the same as the standard percentage system and retains one decimal place.

[0057] Preferably, the specific content of step six is:

[0058] 6.1. Based on the comprehensive health index score of ancient and famous trees and referring to the existing health diagnostic standards for ancient and famous trees in the area where the ancient and famous trees are located, the health level of the ancient and famous trees will be evaluated as normal, weak, severely weak or endangered;

[0059] In this application, it needs to be further explained that the health level division of ancient trees and famous trees in each region is different according to the standards of different regions, and is specifically divided according to the relevant standards of the location of the target ancient trees and famous trees, and the score range of the ancient trees and famous trees health comprehensive index corresponding to each level is also different, and is also determined according to the corresponding standards.

[0060] 6.2. Based on the health grades of ancient and famous trees, the health status of ancient and famous trees of different health grades is described by combining the calculation results of each individual indicator and the stem flow information of the trunk. The following are typical description examples of different health grades:

[0061] Normal: The ancient and famous trees are growing well overall, free from diseases and insect pests, with lush branches and leaves and no damage to the trunks;

[0062] Weak: The overall growth of ancient and famous trees is good, with a crown loss rate of 6-12%. The entire crown tends to shrink inward, branches and leaves occasionally fall off, there are a few diseases and insect pests, the trunk has some damage, and the overall growth trend is declining;

[0063] Severely weak: The ancient and famous trees are severely damaged, the surrounding environment has posed a certain threat to the tree, the ability to adapt to the external environment is poor, and the overall growth is poor;

[0064] Endangered: The overall growth of ancient and famous trees is poor, with many cases of withering and damage, serious diseases and insect pests, and the trees are already on the verge of death.

[0065] Similarly, the descriptions of corresponding grade evaluations are different in different regions, and the grade evaluation descriptions corresponding to the target ancient trees and famous trees in each region shall prevail.

[0066] Preferably, in step seven, the maintenance plans corresponding to different comprehensive health indexes include but are not limited to: soil maintenance and fertilization, water replenishment and drainage, tree maintenance, tree cavity preservation and repair, root rejuvenation, pest and disease control, environmental cleaning and weeding, fencing and signage, fire prevention and lightning protection, and routine inspections.

[0067] In this application, the above-mentioned expressions are further explained as follows:

[0068] Soil maintenance and fertilization: Soil maintenance includes timely loosening of the soil when it becomes compacted. For ancient and valuable trees on slopes, cofferdams and earth piles should be built within the protected area to prevent landslides. If soil is contaminated, the source of the pollution should be promptly removed and the contaminated soil replaced. Fertilization can be done through soil application or foliar application.

[0069] Watering and Drainage: Watering can be done through soil watering or foliar spraying. Surface water should be drained promptly through stem flow or existing ditches. Soil water should be drained through pipes. If drainage is not possible, seepage wells should be dug and pumped out.

[0070] Tree maintenance: Tree maintenance includes timely removal of snow covering ancient and famous trees in winter when there is heavy snow, and prohibition of snow-melting agents within the protection area; timely disinfection and application of wound healing agents on wounds caused by mechanical damage, lightning strikes, etc.; removal of plants that have adverse effects on their growth within the protection area; tree support and reinforcement; and tree hole treatment.

[0071] Cavity Preservation and Repair: Cavity preservation involves sanitation and anti-corrosion measures to prevent or delay decay and prevent water accumulation in the cavity. If the cavity is too large or the trunk is severely damaged, compromising the tree's stability, a keel can be constructed to reinforce the tree before filling and sealing. If necessary, simulated repair treatment can be performed on the cavity surface, and the gaps in the tree can be sealed.

[0072] Root rejuvenation: Root rejuvenation measures should be implemented promptly for ancient and famous trees with root damage exceeding 30%. Analyze the causes of root decline or even decay, and implement targeted improvement measures based on factors such as soil compaction, waterlogging, mechanical damage, and soil contamination.

[0073] Pest and disease control: Adopt green and environmentally friendly measures to carry out integrated pest management, and cut down or remove plants that affect the growth of ancient and famous trees or within the protected area.

[0074] Environmental tidying and weeding: remove obstructions, improve hardened ground, and remove weeds.

[0075] Fences and signs: Fences and signs should be set up 3m away from the tree trunk. The sign elements include: name, Latin scientific name, family, protection level, number, etc.

[0076] Fire and lightning protection: Deploy fire prevention facilities around ancient and famous trees, and install lightning protection facilities for tall ancient and famous trees.

[0077] Routine inspections: Regular manual inspections of the environment around ancient and famous trees and their growth conditions.

[0078] Preferably, in step eight, the specific implementation process of the maintenance plan is:

[0079] 8.1. Maintenance task issuance: Issue the corresponding maintenance task to the maintenance personnel

[0080] 8.2. Implementation of maintenance tasks: Maintenance personnel implement maintenance tasks

[0100] 1.2. Determine the information of the ancient and famous trees that need to be tested based on the indicators in step 1.1.

[0101] Specifically, based on the relevant standards for health evaluation of ancient trees and famous trees in the "Technical Regulations for Health Diagnosis of Ancient Trees and Famous Trees in Zhejiang Province", an ancient tree and famous tree health evaluation model is established. It can be understood that the evaluation standards in the "Technical Regulations for Health Diagnosis of Ancient Trees and Famous Trees in Zhejiang Province" are the ancient tree and famous tree health evaluation model in this application.

[0102] 2. Obtaining information on the status of ancient and famous trees from multiple angles: (This information is based on the relevant information required for health assessment in the "Technical Regulations for Health Diagnosis of Ancient and Famous Trees in Zhejiang Province")

[0103] The various angles for obtaining information on the status of ancient trees and famous trees include: obtaining spectral information on the surface of ancient trees and famous trees, obtaining image information on different parts of the surface of ancient trees and famous trees, obtaining stress wave information on the internal decay status of the trunks of ancient trees and famous trees, obtaining stemflow information on the trunks of ancient trees and famous trees, obtaining distribution information on the root systems of ancient trees and famous trees, obtaining meteorological data on the surrounding environment of ancient trees and famous trees, obtaining soil data at different depths under the crowns of ancient trees and famous trees, and obtaining information on diseases and insect pests around ancient trees and famous trees.

[0120] In this embodiment, according to the information data obtained, the specific analysis process and the obtained analysis results are as follows: Figure 4 (leaf health analysis) and Figure 5 (Analysis of Stem Flow Data) shows that it is necessary to explain that Figure 5 The horizontal values in the table represent the time of stem flow acquisition, that is, the stem flow acquisition date in 2024 (September 20 to September 27) and the specific time, and the vertical values represent the stem flow rate in cm / s. The overall information analysis results of the monitoring data of the Torreya grandis ancient tree in Zhanao Village are as follows Figure 6 As shown, it needs to be further explained that the relevant image information is not used as an illustration, so the results of relevant data analysis are provided.

[0121] 4. Determine the classification of each monitoring indicator for the protection of ancient and famous trees;

[0122] The protection and monitoring indicators for ancient and famous trees include six dimensions: leaves, branches, trunks, roots, growth environment, and pests and diseases.

[0123] like Figure 7 As shown: Specifically, the health of ancient and famous trees is evaluated from six dimensions, namely leaves, branches, trunks, roots, growth environment, and pests and diseases, including 11 indicators such as normal leaf rate (%), degree of branch (treetop) damage (%), degree of trunk (first-level branch) damage (%), trunk inclination (°), degree of bark damage (%), internal decay of trunk (%), degree of root damage (%), degree of hardening under the crown (%), degree of soil cover (fill) (%), soil pH, and degree of pest and disease damage. Furthermore, the monitoring value of each indicator corresponds to the indicator grade in the model. Furthermore, a weight value is set for each indicator to evaluate the impact of different indicators on health. Specifically, the indicators of the above six dimensions are graded according to the grading indicators in the "Technical Regulations for Health Diagnosis of Ancient and Famous Trees in Zhejiang Province".

[0124] 5. Based on the classification of the ancient and famous tree protection monitoring indicators in step 4, use the analysis data in step 3 to calculate the health status of the ancient and famous trees;

[0125] 5.1. Calculate the indicators in step 4 based on the ancient and famous tree health evaluation model: First, determine the indicator's classification based on the measured value. Then, based on the score range of the classification, use the interpolation method to calculate the score of the indicator. The calculation method is as follows:

[0126] Ni=score Min +(value-value Min )*(score Max -score Min ) / (value Max -value Min )

[0127] Among them, Ni is the score of the indicator (i represents the i-th indicator), score Min Indicates the lowest value of the indicator grading score range, score Max Indicates the highest value of the indicator grading score interval, value indicates the indicator measurement value, value Min Indicates the lowest value of the indicator classification interval, value Max Indicates the highest value of the indicator classification range.

[0128] like Figure 8 As shown, specifically, according to the above standards, the scores of various indicators of the Torreya grandis from Zhan'ao Village in this embodiment are: normal leaf rate 9.6 points, branch (treetop) damage degree 9.6 points, trunk (first-level branch) damage degree 8 points, trunk inclination 6 points, bark damage degree 10 points, trunk internal rot 6, root damage degree 9.2 points, crown hardening degree 10, soil cover (fill) degree 9.4, pH (slightly acidic plants) 9, and pest and disease damage degree 10.

[0129] 5.2. Calculation of comprehensive health index score:

[0130] Among them, S is the comprehensive health index score of ancient and famous trees, with one decimal place retained, Ni is the score of the i-th secondary indicator, with one decimal place retained, Ai is the weight corresponding to the i-th secondary indicator, and n is the number of secondary indicators.
