[0002] Since the 20th century, human activities have intervened and destroyed the natural environment at an unprecedented rate, resulting in the continuous degradation of ecosystems and a sharp decrease in biodiversity worldwide. Ecological protection and restoration projects aimed at ecological protection and restoration are considered to be an important means to effectively respond to ecological environmental degradation and improve ecosystem services. How to scientifically and rationally evaluate the level of ecological restoration after the implementation of ecological protection and restoration projects has become a research hotspot.

[0050] Before describing the specific embodiments of the present invention, the overall concept of the present invention is described as follows:

[0051] The present invention is mainly developed for the ecological restoration effectiveness evaluation process. At present, biodiversity restoration assessment mainly uses manual surveys and infrared cameras to conduct a census of regional biodiversity or specific groups. There are practical problems of long survey cycles and high costs. In addition, it is difficult for mammals, birds and other animals to recover quickly in a short period of time. Conducting a census-based biodiversity survey and assessment often easily leads to "excessive" monitoring, resulting in increased monitoring and assessment costs.

[0052] Therefore, the present invention proposes a method for evaluating the effectiveness of biodiversity restoration at an engineering scale. The present invention uses arthropods with rapid biological recovery as indicator species, optimizes the method for evaluating the effectiveness of biodiversity restoration at an engineering scale, develops a biological restoration evaluation index model, and realizes the quantitative evaluation of the effect of biodiversity restoration. Arthropods are small in size, large in number, widely distributed, and have a short reproductive cycle. They are highly sensitive to climate and environmental changes, can respond quickly to the environment, have stable interannual changes, and have simple survey methods, so that they can be used as biological indicator species to reflect the interannual changes in the ecological environment and evaluate the effectiveness of the implementation of ecological restoration projects.

[0053] After introducing the overall concept of the present invention, in order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0054] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of this specification should be understood by people with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in one or more embodiments of this specification do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0055] For ease of understanding, the terms involved in the embodiments of the present invention are explained below:

[0056] Simpson dominance index: Simpson dominance index, also known as Simpson index, is an indicator used to measure species diversity in a community. It reflects the uneven distribution of species by calculating the proportion of the number of species in the community.

[0057] Shannon's diversity index: Shannon's diversity index is a measurement index based on information theory. At the landscape level, it is equal to the negative value of the sum of the area ratio of each patch type multiplied by the natural logarithm of its value.

[0058] Margalef's richness index: Margalef's richness index is a commonly used biodiversity indicator used to reflect the species richness of a community. It refers to the number of species in a community or environment, and is also an index of the degree of species richness in a biological community (or sample).

[0059] Pielou's evenness index: Pielou's evenness index is an indicator used to measure the relative uniformity of the distribution of species in a given area or ecosystem.

[0060] In one embodiment, Figure 1 As shown, a method for evaluating the effectiveness of biodiversity restoration at an engineering scale is provided, including the following steps:

[0061] Step S101, acquiring basic data for biological restoration assessment, and obtaining evaluation indicators according to the basic data for biological assessment.

[0062] Specifically, basic data of biological restoration assessment of the area to be assessed are obtained, and specific evaluation indicators are obtained based on the basic data of biological restoration assessment.

[0063] On this basis, the evaluation indicators are obtained according to the biological evaluation basic data, which also include:

[0064] Acquiring biological restoration assessment analysis data, and extracting evaluation data classes based on the biological restoration assessment analysis data;

[0065] An evaluation table is obtained according to the evaluation data class.

[0066] Specifically, biological restoration evaluation and analysis data are obtained, and multiple evaluation data classes can be analyzed based on the biological restoration evaluation and analysis data. An evaluation table is created according to the evaluation data classes. The evaluation table is shown in Table 1 below.

[0067]

[0068] Table 1 Evaluation table

[0069] In this embodiment, the diversity, richness and uniformity of the biological community jointly determine the level of biodiversity recovery, which is used as the first-level evaluation data class. Six evaluation data classes are selected, including Simpson dominance index, Shannon diversity index, total number of individuals, number of species, Margalef richness index, and Pielou uniformity index. The evaluation data classes are representative and simple to calculate. A biodiversity restoration effectiveness evaluation index system is constructed, and the calculation method of the biological recovery assessment index is clarified. According to the importance of the evaluation data class and the correlation between the evaluation data classes, the hierarchical analysis method is used to determine the weight of each evaluation data class.

[0070] On this basis, basic data for biological restoration assessment are obtained, including:

[0071] Obtaining basic geographic data of the area to be evaluated, and obtaining a test plot according to the basic geographic data of the area to be evaluated;

[0072] Setting a sample plot on the test plot to obtain a plurality of sampling points;

[0073] Through the sampling points, basic data for biological restoration assessment are obtained; wherein the basic data for biological restoration assessment include: the number of species individuals, the total number of community individuals, and the number of community groups.

[0074] Specifically, collect engineering information such as engineering design, implementation plan, project scope vector map of ecological protection and restoration projects, grasp the start and completion time of project implementation and specific protection and restoration measures; collect basic geographic data such as engineering area elevation, land use type, vegetation type, soil type, and conduct on-site surveys to obtain basic geographic data on the natural environment, ecosystem type and habitat characteristics of the area to be evaluated.

[0075] Typical and representative vegetation areas under different restoration measures in the area to be evaluated are selected as test plots. There are no less than 3 test plots of each type, which are set at the top, middle and bottom of the slope. The test plots are separated as far as possible, and in principle, the interval is required to be at least 100 meters. In the adjacent areas of the test plots, areas with similar habitat conditions such as altitude, slope, slope direction, vegetation, soil, etc. to the restoration area and where no ecological restoration project has been implemented are selected as control plots.

[0076] Set up sample plots for the test plots. No less than 3 sample plots are randomly set up in each test plot, and the sample plot area is not less than 100m 2 , according to the actual situation of the sample, such as Figure 2 As shown in the figure, five sampling points are set in the sample plot by using the diagonal method. The sampling points are set at the center of the sample plot and at the positions of 4m from the center of the two diagonals of the sample plot. Another method can also be used, such as Figure 3As shown, five sampling points were set in the sample plot using the linear method. The linear method set one sampling point every 2 m along the middle of the sample strip.

[0077] Surface traps were used to continuously survey and sample arthropods such as silkworms and spiders. Figure 4 As shown, a trap cup is set up at each sampling point. The diameter of the trap cup is 8cm, the height is 12cm, and the capacity is about 450ml. When the trap cup is buried, the cup mouth is flush with the ground or slightly lower than the ground. A mixed solution of about 2 / 3 saturated salt water and a few drops of detergent is poured into the cup. A piece of iron rain shield is supported by a bamboo stick 5cm above the cup. Saturated salt water can preserve the captured animals, detergent can destroy the surface resistance of the liquid surface, and insects are not easy to escape after naturally falling into the cup. The rain shield can prevent rainwater and debris from directly entering the cup.

[0078] Summer is the active period of arthropod activities. Surface arthropods are collected from June to September each year. In order to prevent the high temperature in summer from evaporating the solution in the trap cup, the sampling cycle is 7 days, and samples are collected and the sample solution is replaced. Sampling monitoring is carried out for no less than 1 month. The samples of 5 trap cups in a sample plot are combined and directly placed in a nylon bag or nylon net. The sample solution is filtered out, and a label with sampling information is placed. The sampling information includes sampling time, sampling personnel, sample site number, location, longitude and latitude coordinates, etc. The label is sealed with a tie rope or rubber band to prevent the sample from scattering. In order to prevent the sampling information on the label from being blurred due to water, it is advisable to write in pencil. At the same time, in order to prevent the label from being worn or damaged, at least 2 labels should be placed and the writing surface should be folded inward. The whole bag of collected samples is placed in a plastic jar filled with anhydrous ethanol for storage, and the label with sampling information is pasted on the jar. The anhydrous ethanol should completely cover the sample to prevent the captured arthropods from rotting.

[0079] Take out the nylon bag containing the captured arthropods and place it in a hard white plastic square basin to reduce the interference of the basin color and facilitate clear identification of arthropods. Pour a small amount of clean water into the basin, tilt the basin, clamp the seal of the nylon bag with tweezers and immerse it in water, gently wave it back and forth to avoid damaging the arthropods themselves, and try to filter out all the mud and sand in the bag to reduce the difficulty of observation. Then open the seal and pour out the arthropods for identification.

[0080] Refer to the classification and identification materials such as "China Soil Animal Retrieval Atlas" (Yin Wenying, 1998), "China Subtropical Soil Animals" (Yin Wenying, 1992), "China Insect Ecology Atlas" (Zhang Weiwei & Li Yuansheng, 2019), "China Spider Ecology Atlas" (Zhang Zhisheng & Wang Luyu, 2019), and "Insect Taxonomy" (Cai Banghua, 2017). Large arthropods can be directly selected for identification and counting. For arthropods that need to be made into specimens, insect needles are inserted and labels with names, sampling time, and test plot information are attached at the same time; for arthropods with smaller size and larger numbers, such as ants, mosquitoes, flies, etc., the bottom of the plastic basin can be divided into four parts, one of which is counted and the number is multiplied by four; all arthropods with smaller size and smaller number are selected and accurately counted. Arthropods that cannot be seen with the naked eye are selected and observed with a small magnifying glass with light, or placed on a culture dish and observed under a microscope. After the classification and identification of arthropods in a test plot are completed, the names and numbers of arthropods in the test plot are recorded and counted to obtain basic data for biological restoration assessment.

[0081] On this basis, the evaluation indicators obtained according to the biological evaluation basic data include:

[0082] The evaluation index is obtained according to the biological restoration assessment basic data and the evaluation table; wherein the evaluation index includes: Simpson dominance index, Shannon diversity index, total number of individuals, Margalef richness index, Pielou evenness index and number of community groups:

[0083]

[0084]

[0085]

[0086] M=(S-1) / ln N

[0087] J=H / ln S

[0088] Where D represents the Simpson dominance index, P i represents the ratio of the number of individuals of the i-th species n to the total number of individuals in the community N, S represents the number of groups in the community, H represents the Shannon diversity index, N represents the total number of individuals, and n i represents the number of individuals of the i-th species, M represents the Margalef richness index, and J represents the Pielou evenness index.

[0089] Specifically, the test plots are used as the smallest statistical unit, and the basic data of biological restoration assessment in the test plots are used to calculate the evaluation indicators of each test plot and the control plot. Based on the overall changes in the arthropod community in the plots at the top, middle and bottom of the slope, the calculation results of the evaluation indicators of each test plot under the same type of restoration measures are arithmetic averaged to comprehensively reflect the biodiversity restoration effect under this type of restoration measures. The calculation methods of each evaluation indicator are as follows:

[0090] Simpson Dominance Index:

[0091] Shannon Diversity Index:

[0092] Total number of individuals:

[0093] Total number of species: S = number of community groups

[0094] Margalef richness index: M = (S-1) / ln N

[0095] Pielou uniformity index: J = H / ln S

[0096] Where: P i is the ratio of the number of individuals n of the i-th species to the total number of individuals N in the community, n i is the number of individuals of the i-th species, N is the total number of individuals in the community, and S is the number of groups in the community.

[0097] Step S102, standardizing the evaluation index to obtain a standard evaluation index.

[0098] Specifically, the monitoring values ​​of the control plots are identified as reference values ​​under ideal conditions (less human interference), and the monitoring values ​​of the monitoring plots in the evaluation area are used as actual values. The concept of relative change is used to evaluate the effectiveness of biological restoration by the difference between the reference value and the actual value. Since the dimensions of the evaluation index data are not uniform and cannot be compared and calculated, the relative change data of each evaluation index are standardized to eliminate the differences in the numerical magnitudes of the evaluation indexes.

[0099] On this basis, the evaluation indicators are standardized to obtain standard evaluation indicators including:

[0100] Standardization is performed according to the following formula:

[0101]

[0102] Among them, X represents the standard evaluation index, X R represents the evaluation index, X C Indicates the reference value corresponding to the evaluation index.

[0103] Step S103, obtaining a biological recovery evaluation index according to the standard evaluation index.

[0104] Specifically, based on the standard evaluation indicators, the biological restoration assessment index can be calculated.

[0105] On this basis, according to the standard evaluation indicators, the biological restoration evaluation index is obtained, including:

[0106] Classifying the standard evaluation indicators to obtain indicator classification;

[0107] According to the index classification, an index score is obtained;

[0108] According to the indicator scores, standard indicator scores are obtained;

[0109] According to the standard indicator scores, a biological restoration assessment index is obtained.

[0110] Specifically, according to the size of the standardized standard evaluation indicators, the change range of each standard evaluation indicator is divided into 5 levels, namely, significantly improved, slightly improved, no obvious change, slightly reduced, and significantly reduced. The score threshold is assigned to each level of standard evaluation indicators. The classification and indicator scores of each standard evaluation indicator are shown in Table 2 below.

[0111] Grading Significantly improved Slightly improved No significant changes Slightly reduced Significantly reduce Index value X≥0.6 0.2<X<0.6 -0.2≤X≤0.2 -0.6<X<-0.2 X≤-0.6 Points [80,100] (60,80) [40,60] (20,40) [0,20]

[0112] Table 2 Standard evaluation index classification and index score

[0113] In order to ensure the continuity of the indicator scores within each grading range and eliminate the situation where the indicator scores on both sides of the threshold are too different due to grading, ±80% of the relative change is taken as the best expected value and the lowest expected value, which are assigned 100 points and 0 points respectively, and the standard indicator scores corresponding to the indicator scores are calculated using linear interpolation within the interval.

[0114] Finally, the biological restoration assessment index was calculated based on the standard indicator scores.

[0115] On this basis, according to the indicator scores, the standard indicator scores include:

[0116] The standard index score is obtained according to the following formula:

[0117]

[0118] Among them, f(X) represents the standard indicator score, and X represents the indicator score.

[0119] On this basis, according to the standard indicator scores, the biological restoration assessment index is obtained, including:

[0120] The biological recovery assessment index is obtained according to the following formula:

[0121]

[0122] Where BRAI represents the biological restoration assessment index, f(X) represents the standard index score, ω j Represents the weight of the jth evaluation index.

[0123] Specifically, the calculation formula of the biological recovery assessment index BRAI is as follows:

[0124]

[0125] Where: f(X) represents the standard index score after the jth evaluation index is standardized, ω j Represents the weight of the jth evaluation index. BRAI represents the biological restoration assessment index, that is, the degree of biodiversity recovery in the project area after the implementation of the ecological restoration project. The higher the value, the better the recovery effect, and vice versa.

[0126] Step S104: evaluating the effectiveness of biodiversity restoration according to the biorecovery evaluation index.

[0127] Specifically, the effectiveness evaluation work is carried out according to the biodiversity restoration effectiveness evaluation index system, and the biodiversity restoration effectiveness is divided into four levels according to the total score of the biological restoration assessment index, namely excellent, good, medium and poor, as shown in Table 3 below.

[0128]

[0129] Table 3 Biodiversity restoration effectiveness classification

[0130] Evaluate the effectiveness of biodiversity restoration according to this biodiversity restoration effectiveness grading table.

[0131] The present invention uses arthropods with rapid biological recovery as indicator species, optimizes the biodiversity restoration effectiveness assessment method at the engineering scale, develops a biological restoration assessment index model, and realizes the quantitative assessment of the biodiversity restoration effect. The arthropod-based effectiveness assessment method proposed in the present invention has a short survey cycle and a small amount of field work. Compared with the traditional biodiversity census, it effectively reduces the time, labor and economic costs of the assessment work. The constructed biodiversity effectiveness assessment model has a simple calculation method and can realize a quantitative assessment of the biodiversity restoration effect. The engineering-scale biodiversity restoration effectiveness assessment conducted by the present invention has high accuracy, selects 6 key indicators in terms of biological group diversity, richness and uniformity, can accurately reflect the changes in arthropod populations, and adopts a combination of quantitative and qualitative evaluation methods, which effectively improves the scientificity and effectiveness of biodiversity assessment.

[0132] It should be noted that the method of the embodiment of the present invention can be performed by a single device, such as a computer or a server.
