[0055] Embodiment 2

[0056] The present application provides a method for demarcating the range of an Antarctic protection area based on position information, uses the position information of animals returned by animal satellite trackers to analyze the position and path of the animals during the breeding, molting and migration periods, calculates the migration range and hunting range of the protected animal population, and obtains the key protection range of the protected animal population through superimposed analysis.

[0057] The present application provides a method for demarcating the range of an Antarctic protection area based on position information, uses the position information of animals returned by animal satellite trackers to analyze the position and path of the animals during the breeding, molting and migration periods, calculates the migration range and hunting range of the protected animal population, and obtains the key protection range of the protected animal population through superimposed analysis. Figure 6 Figure 6 The present application provides another method for demarcating the range of an Antarctic protection area based on position information. As shown in FIG. 1, the method for demarcating the range of an Antarctic protection area based on position information comprises the following steps. Figure 6

[0058] Step 301, obtaining preset geographic information and setting a protection area for a protected animal.

[0059] In this step, the position information of the satellite tracker is imported into the geographic information system software to obtain the preset geographic information, and each protection area of the protected animal is set according to the activity characteristics of the protected animal.

[0060] The satellite tracker is used to obtain position information and obtain information based on Antarctic geographic information, including longitude and latitude data.

[0061] It should be noted that the geographic information system software is used to analyze and process a geographic information system (GIS, Geographic Information System), the GIS technology integrates the unique visual effect of geographic information and the geographic analysis function with general database operations, and a geographic spatial information model is formed by a computer program and geographic data, the objective world is abstracted into a spatial data model, and the information of the analysis and prediction of natural processes is used for management and decision-making. ​​

[0062] The geographic information system software includes: ArcGIS, QGIS, SAGA GIS and GRASS GIS, etc.

[0063] Optionally, the activity characteristics of the protected animals include: based on the behavioral characteristics and movement trajectories of the protected animals, the areas where the movement trajectories of the protected animals regularly move between land and sea are regarded as breeding areas; the areas where the movement trajectories of the protected animals continuously appear on land or fixed ice and the amount of activity is extremely small are regarded as molting areas; the areas where the movement trajectories of the animals are in the ocean and move in one direction for many consecutive days are regarded as migration passage areas.

[0064] Specifically, the breeding area, molting area and migration passage area are set up to set up targeted methods for protecting the protected animals according to the protected animals in different areas.

[0065] For example, the feathers of the little penguins that have not yet molted in the molting area lack oily substances and are very likely to be frostbitten or even die after being soaked by rainwater.

[0066] Specifically, the preset geographic information is obtained, and the land and ocean areas are distinguished. The areas are divided by the coastline or the outer edge of the fixed ice, and the areas on the land side are designated as land protection areas, and the areas on the sea side are designated as marine protection areas. The land protection areas are aimed at protecting areas during the breeding or activity period of animals on land or ice, and the marine protection areas are aimed at protecting areas during the hunting or migration period of animals in the ocean.

[0067] According to the activity characteristics of the protected animals, the terrestrial protection zone includes the molting area and the land part of the breeding area, and the marine protection zone includes the migration passage area and the marine part of the breeding area.

[0068] It should be noted that the land part of the breeding area is defined as the land breeding area, and the marine part of the breeding area is defined as the marine breeding area. According to the preset geographical information, the protected animal protection area is divided into the molting area, the land breeding area, the marine breeding area and the migration channel area, which are used to implement corresponding protection measures for the protected animals in different periods in the molting area, the land breeding area, the marine breeding area and the migration channel area.

[0069] Specifically, for the terrestrial protected areas, the seaward boundary is the coastline or the outer edge of the fixed ice, and the landward boundary is the protected animal distribution area and the watershed ridge line or the boundary of the independent geographical unit and the coastline; for the marine protected areas, the core area and buffer zone are delineated according to the activity patterns of the target organisms.

[0070] Among them, the area enclosed by the outer edge of the protected animal distribution area and the coastline is the land core area, and other land areas except the land core area are land buffer areas.

[0071] Specifically, the land core area includes the molting area and the land breeding area, and other areas without protection of animal activity areas are the land buffer area.

[0072] In step 302, according to the protection area, a protection animal area distribution map is drawn.

[0073] In this step, according to the protection area, a grid with a side length of a is set by using the geographic information system software, the number of times and the density of the protection animals appearing in each grid are calculated, and a protection animal area distribution map is drawn.

[0074] Specifically, a grid covering the target research area of a×a square kilometers is drawn by using the geographic information system software, and the number n of protection animal longitude and latitude points falling on each grid is calculated by using the geographic information system software superposition analysis. i The density p of protection animal path points falling in each grid is calculated. i The density calculation formula of the number of times of the protection animals appearing can be expressed as formula (1):

[0075]

[0076] Wherein, p i represents the density of the number of times of the protection animals appearing in the i-th grid; n i represents the number of times of the protection animals appearing in the i-th grid; and a represents the grid side length.

[0077] According to the calculated p i value, it is analyzed that the area with high land distribution density of the protection animals is p i .

[0078] For example, the protection animals in the breeding area appear hunting behavior, frequently go back and forth between the marine protection area and the land protection area, and the p i value is high; the activity amount of the protection animals in the molting area is small, and the p i value is almost 0.

[0079] It should be noted that according to the set marine breeding area, the hunting range of the protection animal population is analyzed by superposition analysis to obtain the marine breeding core area and the marine breeding buffer area of the protection animal population.

[0080] Specifically, for the marine breeding core area, the radius of the marine breeding core area can be calculated by formula (2):

[0081]

[0082] Wherein, R bc represents the radius of the marine breeding core area; and di,j represents the distance from the nest hole when the i-th protected animal preys for the j-th time; n represents the total number of observations of the prey of the protected animal.

[0083] Optionally, according to the radius R of the marine breeding core area bc , a circular arc is drawn with the centroid of the terrestrial breeding area as the center, intersecting the coastline and the outer edge of the fixed ice, and the enclosed area is the marine breeding core area. Draw the area map of the marine breeding core area, which is the first area distribution map, and the area is S bc .

[0084] Specifically, for the marine breeding buffer zone, the radius of the marine breeding buffer zone can be calculated as formula (3):

[0085]

[0086] wherein: R bb represents the radius of the marine part of the breeding area buffer zone; represents the maximum distance from the nest hole when the i-th protected animal preys; m represents the number of observed protected animals.

[0087] Optionally, according to the radius R of the marine breeding buffer zone bb , a circular arc is drawn with the centroid of the terrestrial breeding area as the center, intersecting the coastline and the outer edge of the fixed ice, and the enclosed area is the marine breeding core area. Draw the area map of the marine breeding core area, which is the first area distribution map, and the area is S bb .

[0088] It should be noted that according to the set migration channel area, the migration range of the protected animal population is analyzed to obtain the migration channel core area and the migration channel buffer area of the protected animal population.

[0089] Specifically, for the migration channel core area, the radius of the migration channel core area can be calculated as formula (4):

[0090]

[0091] wherein: R mc represents the radius of the migration channel core area; r i,j represents the distance from the coastline or the outer edge of the fixed ice of the i-th protected animal at the j-th position data; N represents the total amount of position data.

[0092] Optionally, the coastline and the outer edge of the fixed ice are taken as the starting point, and the area map of the migration channel core area is drawn with R mc as the radius of the migration channel core area, forming the third area distribution map with an area of S mc.

[0093] Specifically, for the migration channel buffer zone, the radius of the migration channel core zone can be calculated as formula (5):

[0094]

[0095] wherein R mb represents the radius of the migration channel buffer zone; represents the maximum distance from the coastline or the outer edge of the fixed ice when the i-th protected animal migrates; m represents the number of observed protected animals.

[0096] Optionally, the area map of the migration channel buffer zone is drawn from the coastline and the outer edge of the fixed ice as the starting point, with R mb as the radius of the migration channel buffer zone, and the area map formed is subtracted from the area coinciding with the third area map, i.e. the migration channel buffer zone area map is taken as the fourth area distribution map, with the area being S mb .

[0097] Optionally, the land core zone distribution map is drawn according to the land core zone, which is the fifth area distribution map; and the land buffer zone distribution map is drawn according to the land buffer zone, which is the sixth area distribution map.

[0098] Step 303, setting the protection time to formulate the protection strategy according to the protected animal area distribution map.

[0099] In this step, according to the areas of the first area distribution map, the second area distribution map, the third area distribution map, the fourth area distribution map, the fifth area distribution map and the sixth area distribution map, the seasonal management time is respectively delimited as the protection time according to the activity law of the protected animals, the time t1 and t2 when the protected animals enter and leave the corresponding area within the 95% confidence interval are respectively calculated according to the time and position information obtained by the animal tracker, the start and stop times of the protection time are respectively taken as t1-15 days and t2+15 days, and the protection time T is t2+15-(t1-15) = t2-t1+30 days.

[0100] Specifically, the data obtained by the animal tracker is the time of biological activity and the corresponding latitude and longitude information obtained by the satellite tracker.

[0101] It should be noted that the 95% confidence interval is used to statistically predict the time when the protected animals enter and leave the corresponding area, in order to better estimate the overall parameters.

[0102] Optionally, the protection time is set to formulate the protection strategy.

[0103] For example, during the seasonal protection time, the following activities are prohibited in the core area of the migration channel: hunting, fishing, collecting, buying and selling protected objects, and directly discharging pollutants into the sea; daily patrol and management are organized in the buffer zone of the migration channel.

[0104] It can be seen that the present application uses satellite trackers to obtain the location information of protected species, solves the problem of the previous protection area range definition, which is not strict and lacks analysis methods, improves the scientificity and accuracy of the protection area range selection, accurately divides the protection area range, and provides a method with reliable basis for the protection area range.

As shown in Figure 7 , the method for delineating the Adelie penguin protection area in the Ross Sea region of Antarctica comprises:

[0107] Step 401, setting the penguin protection area according to the preset geographic information obtained by the satellite tracker.

[0108] In this step, the latitude and longitude data of the Adelie penguin in the Ross Sea region of Antarctica obtained by the satellite tracker is imported into the geographic information system software, and the grid and density analysis are set by using the geographic information system software, and the protection area of the protected animal is set in combination with the geographic information of the Ross Sea region.

[0109] Specifically, the Ross Sea region is divided according to the coastline or fixed ice edge line, and the land side region is divided into the Adelie penguin land protection area, and the sea side region is divided into the Adelie penguin marine protection area.

[0110] Among them, the regions with high and low density are divided according to the density analysis, and the land area with high density is obtained as the Adelie penguin land breeding area, and the land area with low density is obtained as the Adelie penguin molting area.

[0111] Optionally, the number of Adelie penguins is 15, and the grid size is 50x50km.

[0112] Specifically, the range of the Adelie penguin land breeding area is the range of the region enclosed by the land edge of the Ross Sea region of Antarctica and the boundary of the density analysis.

[0113] Step 402, drawing a penguin area distribution map according to the penguin protection area.

[0114] In this step, according to the single prey radius of the Adelie penguin in the Adelie penguin protection area and the maximum value of the prey radius, the area distribution map of the Adelie penguin marine protection area is drawn.

[0115] Wherein, the single prey radius a of the Adelie penguin is obtained ij Referring to Table 1, Table 1 is the single prey radius of the Adelie penguin in the Ross Sea region, and the range radius R1 of the Adelie penguin marine breeding core area is calculated according to formula (6) as 75.6 km.

[0121] Wherein, the single prey radius a of the Adelie penguin is obtained imax Referring to Table 2, Table 2 is the maximum value of the single prey radius of the Adelie penguin in the Ross Sea region, and the range radius R2 of the Adelie penguin marine breeding buffer area is calculated according to formula (7) as 93.9 km.

[0124]

[0125] Wherein: R2 represents the radius of the marine part of the breeding area buffer area; represents the maximum distance from the nest when the i-th Adelie penguin preys; m represents the number of observed Adelie penguins.

[0127] Specifically, according to the distance r of each position data of the Adelie penguin in the Ross Sea region from the coastline or the outer edge of the fixed ice ij , the radius R3 of the Adelie penguin migration channel core area is calculated according to formula (8) as 12.3 km,

[0128]

[0129] Wherein: R3 represents the radius of the migration channel core area; r i,j represents the distance of the jth position data of the ith Adelie penguin from the coastline or the outer edge of the fixed ice; N represents the total amount of position data.
