[0054] The present invention will be further described in detail below with reference to the accompanying drawings:

[0055] The present invention provides an airport bird strike prevention method based on insect situation monitoring, as Figure 1 shown, including the following steps:

[0056] S1. Set up N insect situation monitoring points, and set the acquisition period D days for insect body data;

[0057] In the soil area of the adjacent runway area such as the airport touchdown zone, set up N insect situation monitoring points. Preferably, N≥20, and the number of each insect situation monitoring point is n, where n = 1, 2, 3... N.

[0058] Use insect situation monitoring equipment such as insecticidal lamps to capture various insects within its capture range, and regularly collect the insect bodies captured at each monitoring point. The collection period is D days, preferably 10≤D≤30.

[0059] S2. Obtain the insect body data of each insect situation monitoring point within the acquisition period, and establish an insect situation database;

[0060] The worm body data includes the types of insects collected at each insect situation monitoring point and the worm body mass of each type of insect.

[0061] The total number of insect types observed at each insect situation monitoring point is I. An insect situation database for the collection period is established as w{i, n}, where i = 1, 2... I and n = 1, 2, 3... N.

[0062] Among them, w{i, n} is the total mass of each type of insect obtained at each insect situation monitoring point, that is, the worm body mass of each type of insect at each insect situation monitoring point; i is the number of each type of insect; n is the number of each insect situation monitoring point.

[0063] S3. Based on the established insect situation database, preliminarily determine the insect danger level.

[0064] The specific operations include:

[0065] S301. Based on the insect situation database established in step S2, calculate the total mass W{i} of each type of insect at all insect situation monitoring points in a collection period, which is calculated by the following formula:

[0066]

[0067] Among them, K is the total number of insect situation monitoring points with insects of type i, and K ≤ N.

[0068] S302. Sort the total mass of each type of insect from largest to smallest, and calculate the proportion P of the total number K of insect situation monitoring points where insects of type i are collected in the total number N of all insect situation monitoring points. i , P i = K / N × 100%.

[0069] S303. According to the preset conditions, preliminarily determine the insect danger level.

[0070] The preset conditions include:

[0071] The first preset condition: The total mass ranking of insects of type i is in the top 20% of all types of insects.

[0072] The second preset condition: P i > 30%.

[0073] To preliminarily determine the insect danger level, the specific operations include:

[0074] Insect types that simultaneously meet the first preset condition and the second preset condition are defined as high-risk insects;

[0075] Insect types that only meet one of the preset conditions are defined as medium-risk insects;

[0076] Insect species that do not meet either of the two preset conditions are defined as low-risk insects.

[0077] S4. Obtain the food structure of the birds caught by the bird net at the airport during the collection period, and adjust the insect risk level.

[0078] By dissecting the birds caught by the bird net at the airport during the same period of the collection period, analyze their food structure, and then adjust the insect risk level.

[0079] For the high-risk insects determined in step S3, if it is found that they are the food source of the birds caught by the net, their risk level remains unchanged.

[0080] For the medium-risk insects determined in step S3, if it is found that they are the food source of the birds caught by the net, their risk level is adjusted to high-risk insects.

[0081] For the low-risk insects determined in step S3, if it is found that they are the food source of the birds caught by the net, their risk level is adjusted to medium-risk insects.

[0082] For the above three cases, if it is found that they are not the food source of the birds caught by the net, the insect risk level remains unchanged.

[0083] In the present invention, the risk level of insects is determined based on the types of insects collected, the total mass, and whether they are the food source of the birds caught by the net during a collection period, and then the key areas of insect conditions are determined, and ecological control measures are adopted to improve the prevention level of bird strikes at the airport.

[0084] The present invention adjusts the risk level of insects in real time according to the types of insects and the food source of the birds caught by the net during different collection periods, so as to improve the prevention level of bird strikes at the airport.

[0085] S5. Determine the key areas of insect conditions according to the adjusted insect risk level.

[0086] For the insect species i with a high-risk insect level, the area delimited with all insect condition monitoring points as the center and a i meters as the radius is determined as the "key area of insect conditions".

[0087] For the insect species i with a medium-risk insect level, the area delimited with the insect condition monitoring point with the insect species i as the center and a i meters as the radius is determined as the "key area of insect conditions".

[0088] For the insect species i with a low-risk insect level, the "key area of insect conditions" is not determined.

[0089] Among them, a i is calculated by the following formula:

[0090] a i = 20(1 + Pi )

[0091] Among them, P i is the proportion of the total number of insect situation monitoring points for the insect species numbered i in the total number of all insect situation monitoring points.

[0092] For different insect species, different drugs are used for targeted killing. For the "key areas of concern for insect situation" of different species of insects determined through the above steps, the dosage of the corresponding drug is increased, and the increase ratio of the dosage is equal to Q i , Q i is the proportion of the total mass of the insect species numbered i in all the insects captured at all insect situation monitoring points.

[0093] The method embodiments of the present invention are as follows:

[0094] Embodiment 1

[0095] The method for preventing bird strikes at airports based on insect situation monitoring proposed by the present invention is illustrated and described below in combination with the example of insect situation monitoring results in the accompanying drawings.

[0096] 1. According to step S1, insect situation monitoring points are set up;

[0097] In the soil area of the adjacent runway area such as the airport approach zone, N insect situation monitoring points (N≥20) are set up, and the number of each monitoring point is n. Insect monitoring equipment such as insecticidal lamps is used to capture various insects within a certain range, and the insect bodies captured at each monitoring point are collected regularly, and the collection period is D days (10≤D≤30).

[0098] In this embodiment, 20 insect situation monitoring points are set up in the soil area of the adjacent runway area such as the airport approach zone, and the numbers of each insect situation monitoring point are 1, 2,..., 20, and the specific layout is as Figure 2 shown. Insect monitoring equipment such as insecticidal lamps is used to capture various insects within a certain range, and the insect bodies captured at each insect situation monitoring point are collected regularly, and the collection period is 15 days.

[0099] 2. According to step S2, an insect situation database is established;

[0100] The total number of insect species observed at each insect situation monitoring point is I, the number of each insect species is i, and the insect body mass w{i, n} of each insect species at each insect situation monitoring point is recorded, and an insect situation database is established based on the above data.

[0101] In this embodiment, within a certain collection period of 15 days, a total of 5 types of insects (I = 5) are monitored, and an insect situation database for this collection period is established based on the insect body mass data of each type of insect at 20 insect situation monitoring points.

[0102] 3. According to step S3, initially determine the insect danger level;

[0103] Based on the established insect situation database, calculate the total weight W{i} of each type of insect at all insect situation monitoring points within a collection period. It is found that the total number of monitoring points for the insects of insect species i is K (K ≤ N), and it is calculated by the following formula:

[0104]

[0105] Based on the monitoring results of all insect situation monitoring points and the total mass of each type of insect calculated by the above formula, divide the danger level of insect i according to the following two preset conditions:

[0106] The first preset condition is that the total mass ranking of the insects of insect species number i is in the top 20% of all types of insects;

[0107] The second preset condition, P i > 30%, P i is the proportion of the total number K of insect situation monitoring points where the insects of insect species number i are collected in the total number N of all insect situation monitoring points, P i = K / N × 100%;

[0108] Insect species that meet both of the above two preset conditions are defined as high-risk insects; insect species that only meet one of the preset conditions are defined as medium-risk insects; insect species that do not meet either of the preset conditions are defined as low-risk insects.

[0109] In this embodiment, the first preset condition is that the total weight of the insects of insect species number 2 ranks in the top 20% of all types of insects, that is, it meets the first preset condition, and the insect species numbered 1, 2, 3, and 4 meet the second preset condition. The detailed information of the 5 types of insects monitored in this embodiment is shown in Table 1.

[0110] Table 1

[0111]

[0112] 4. According to step S4, adjust the insect danger level;

[0113] By dissecting the birds caught in the airport bird-catching net during the same period and analyzing their food structure, the insect danger level is further adjusted. For the high-risk insects determined in step 3, if it is found that they are the food sources of the caught birds, their danger level remains unchanged; for the medium-risk insects determined in step 3, if it is found that they are the food sources of the caught birds, their danger level is adjusted to high-risk insects; for the low-risk insects determined in step 3, if it is found that they are the food sources of the caught birds, their danger level is adjusted to medium-risk insects.

[0114] In this embodiment, if insect species No. 1 and No. 2 are found to be food sources for birds caught in the net, the risk level of No. 1 is adjusted to a high-risk insect, and the risk level of No. 2 remains unchanged. See Table 2 for details.

[0115] Table 2

[0116]

[0117] 5. According to step S5, determine the key areas for pest situation monitoring;

[0118] For insect species i with a high-risk level for insects, the area demarcated with all pest situation monitoring points as the center and a i meters as the radius is determined as the "key area for pest situation monitoring";

[0119] For insect species i with a medium-risk level for insects, the area demarcated with the pest situation monitoring point with insect species i as the center and a i meters as the radius is determined as the "key area for pest situation monitoring";

[0120] For insect species i with a low-risk level for insects, the "key area for pest situation monitoring" is not determined.

[0121] Among them, a i is calculated by the following formula:

[0122] a i = 20(1 + P i )

[0123] Among them, P i is the proportion of the total number of pest situation monitoring points for insect species numbered i in the total number of all pest situation monitoring points.

[0124] In this embodiment, both insect 1 and insect 2 are high-risk insects, and their "key areas for pest situation monitoring" are the areas demarcated with all pest situation monitoring points as the center (the radii are a 1 = 20 × 1.75 = 35 meters, a 2 = 20 × 2 = 40 meters), as shown in Figure 3 ; Insect 3 is a medium-risk insect, and its "key area for pest situation monitoring" is the area demarcated with 8 pest situation monitoring points (2, 4, 6, 8, 10, 16, 18, 19) where this type of insect is collected as the center (the radius is a 3 = 20 × 1.4 = 28 meters), as shown in Figure 4 ; Insect 4 is a medium-risk insect, and its "key area for pest situation monitoring" is the area demarcated with 12 pest situation monitoring points (1, 2, 3, 4, 6, 8, 9, 10, 16, 17, 18, 19) where this type of insect is collected as the center (the radius is a 4 = 20 × 1.6 = 32 meters), as shown in Figure 4As shown; Insect 5 is a low-risk insect, and the "key insect situation attention area" is uncertain.

[0125] For different insect species i, different drugs are used for targeted killing. For the "key insect situation attention areas" of different species of insects determined through the above steps, the dosage of the corresponding drug is increased, and the increase ratio of the dosage is equal to Q i , Q i is the proportion of the total mass of the insect species numbered i among all the insects captured at all insect situation monitoring points.

[0126] In this embodiment, in its corresponding "key insect situation attention area", the increased amounts of the killing dosages of 5 types of insects are shown in Table 3.
