[0002] The spatial selection of intertidal mangrove plants is a key ecological restoration and coastline protection technology. The intertidal zone is the transition area between the ocean and the land. It is affected by the tides and has complex and changeable environmental conditions.

[0003] However, due to the influence of human activities and natural factors, intertidal mangrove plants are facing serious degradation and destruction, resulting in an imbalance in the ecosystem and erosion of the coastline. In order to protect and restore the intertidal mangrove plant ecosystem, spatial matching is required, that is, selecting suitable mangrove plant species and planting locations according to the environmental conditions of different regions and the characteristics of mangrove plants. The purpose of spatial matching is to optimize the distribution of mangrove plants, improve their growth and reproduction success rate, and enhance the stability and resistance of the ecosystem.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The present invention will be further described below in conjunction with the embodiments.

[0040] Example 1 (see Figure 1 ): A method for selecting and combining intertidal mangrove plants in space, comprising the following steps:

[0041] S100, obtaining an intertidal mangrove planting area, and performing regional division on the planting area to generate a plurality of sub-planting areas;

[0042] It should be noted that when dividing the planting area of ​​intertidal mangroves, it can be divided according to equal areas or by the prefecture-level regions to which it belongs, thereby facilitating the generation of multiple sub-planting areas for subsequent convenient planting and analysis of related factors.

[0043] S200, performing correlation factor analysis on the generated sub-planting areas, thereby generating correlation factor values, constructing a correlation matching queue according to the correlation factor values, and determining the sub-planting areas where intertidal mangroves can be planted in the correlation matching queue, thereby determining suitable mangrove tree species and sub-planting areas of their optimal growth zones and marking them as matching planting areas;

[0044] At the same time, the mangrove species that can be included in the sub-planting area are obtained, and the tolerance factor analysis of the mangrove species is carried out to generate the tolerance factor value. According to the tolerance factor value, the tolerant matching queue is constructed, and the mangrove species that can be used to plant intertidal mangroves in the tolerant matching queue are judged and marked as tolerant mangrove species, so as to facilitate the planting structure of mangroves and realize the reasonable planning of vegetation ecology.

[0045] Furthermore, the correlation factor analysis of the above sub-planting areas is performed through a linear analysis model, wherein the calculation formula of the linear analysis model is as follows:

[0046]

[0047] Where: f′ represents the correlation factor value, density xi Indicates the planting density of the sub-planting area, soil xi Indicates soil conditions, tide xi Indicates tidal conditions, xy ty 、xy il and xy de Respectively represent density xi 、soil xi and tide xi The influence weight of fx xy 2 Indicates density xi 、soil xi and tide xi The sum of , β is a constant correction coefficient to avoid f′ being 0, thereby obtaining the associated factor value, and the factor planting area is divided into multiple, then multiple sub-planting areas correspond to multiple associated factor values, thereby, a related queue to be selected is constructed through multiple associated factor values, and in the associated queue to be selected, the associated factor values ​​are arranged in sequence from high to low, thereby the associated queue to be selected can be regenerated, so that the sub-planting areas with high associated factor values ​​in the associated queue to be selected can be pre-determined as matching planting areas, thereby determining the matching planting areas of suitable mangrove species and their optimal growth zones, which is conducive to the construction of mangrove vegetation forests.

[0048] The method to obtain mangrove species that can be included in the sub-planting area and analyze the tolerance factors of mangrove species is:

[0049] Get the tolerance-related characteristics of mangrove species, where the tolerance-related characteristics include growth speed trees Disease resistance trees ;

[0050] Construct tolerance factor values ​​based on the associated characteristics of mangrove speciestrees xi :

[0051]

[0052] Where: sped si and dise si Respectively represent the growth speed trees Disease resistance treesThe impact weight of trees is that there are multiple mangrove species, so multiple mangrove species correspond to multiple tolerance factor values. xi , thus, through multiple tolerance factor value trees xi Construct a tolerant queue to be selected, and arrange the tolerance factor values ​​in sequence from high to low in the tolerant queue to be selected, so that the tolerant queue to be selected can be regenerated, so that mangrove species with high tolerance factor values ​​can be pre-determined as tolerant mangrove species in the tolerant queue to be selected and combined, which is conducive to the construction of mangrove vegetation forest.

[0053] In the above, it should be noted that the types of mangrove species are as follows:

[0054] 1) Avicennia marina

[0055] Avicennia marina, Chinese name Sea Olive, is one of the common mangrove plants, a shrub, 1.5-6.0m tall, with raised stripes on branches, square twigs, smooth and hairless; leaves are nearly sessile, leathery, ovate to obovate, elliptical, cuneate at base, hairless on the surface, shiny, with fine short hairs on the back, and obvious main veins; flowers are yellow-brown, with dense cymes forming heads, and fruits are nearly spherical and hairy, with flowering and fruiting periods from July to October. Avicennia marina is distributed in Guangdong, Fujian, and Taiwan in my country.

[0056] 2) Red Mangrove (Rhizophora stylosa)

[0057] Red sea olive is a common mangrove tree species in my country. It is a tree or shrub, 2 to 7 meters high, with a well-developed prop root at the base. The leaves are elliptical or oblong-elliptical, with a convex tip or blunt short tip, and a broad cuneate base; the midrib and petiole are both green, the petiole is thick, 2 to 3 cm long, and the stipules are long. The peduncle grows from the axil of the current year, which is the same length as the petiole or slightly longer, with flowers 24 to 6 cm, up to multiple. The sepals are light yellow, the petals are shorter than the sepals, and the edges are covered with white long hairs. When the fruit matures, it is inverted pear-shaped, smooth, narrowed at the top, and the hypocotyl is cylindrical. The flowering and fruiting period is autumn and winter.

[0058] 3) Kandelia abovata

[0059] Kandelia ovata, a shrub or small tree, 2 to 3 meters high, is a common mangrove plant. The bark is smooth and reddish brown; the branches are thick and have swollen nodes; the leaves are elliptical, oblong-elliptical or nearly obovate, with entire margins and unclear veins; the flowers are white, with dichotomous cymes, growing in the upper leaf axils; the fruits are conical. Kandelia ovata likes to grow in the deep mudflats of bay silt alluvial deposits. It can adapt to both the beaches with high salinity and the areas flooded with freshwater, and is relatively resistant to flooding; its prop roots are particularly developed, which can help the plant resist the impact of waves, but its growth rate is medium.

[0060] 4)Tung tree (Aegiceras corniculatum)

[0061] Tung tree, also known as candle fruit, is one of the common mangrove plants. It is a shrub or small tree, 1.5-4.0m tall, with hairless twigs, brown-black, alternate leaves, nearly opposite at the top of the branches, leathery leaves, obovate, elliptical or broadly obovate, entire, with recurved edges, densely covered with small pits on both sides, hairless leaves, flat midrib, slightly raised lateral veins, and densely covered with fine hairs on the back of the leaves. The flowers are white, umbels, born at the top of the branches, sessile. The capsule is cylindrical, curved like a crescent, with a gradually pointed top, about 6-8cm long. The flowering period is from December to January-February of the following year, and the fruiting period is from October to December.

[0062] For the qualified standards of mangrove seedlings, please refer to the following table:

[0063]

[0064]

[0065] Therefore, according to the above table, it is convenient to select mangrove species that meet the qualified standards for planting operations.

[0066] It is worth noting that when planting mangrove species in the selected planting area, it is necessary to dig holes and plant:

[0067] Digging holes and planting are carried out simultaneously. The size of the planting holes is 30cm×30cm×25cm. A shovel or hoe is used to dig holes and plant trees. Planting is carried out in late spring or summer, and the time of low tide is used to plant trees. When planting, the nutrient bags must be removed, and the trees must be planted with soil balls. The planting depth should be appropriate to keep the seedlings straight.

[0068] In order to assist the planting of seedlings and prevent them from falling over, each seedling is fixed with a bamboo pole with a height of 2m and a diameter of not less than 2cm. The bamboo pole is inserted into the beach 50cm (relative to the beach surface elevation). Mangrove planting should comply with LY / T1938 regulations;

[0069] Planting is best done in the rainy season, most preferably from May to August. If the hypocotyl planting method is used, planting should be done when the propagule matures. Different tree species have different suitable planting densities. Planting can be done in strip mixed planting, block mixed planting, inter-row or inter-plant mixed planting, irregular mixed planting and other mixed planting methods. Vertical coastlines use sequence mixed planting of tree species suitable for the tide level. At the same tide level, deep-rooted and shallow-rooted, positive-tolerant and shade-tolerant, and tree and shrub species are mixed. Human activities such as grazing, digging economic animals, raising poultry, fencing, and mooring are prohibited in the restoration area. For dead or lost seedlings, timely replanting and repair should be carried out, and harmful organisms (such as barnacles and enteromorpha) and garbage should be removed regularly. When restoring mangroves, different mangrove plant seedlings should be selected according to different elevations for planting and restoration.

[0070] It is worth noting that when the selected planting area is near the beach area, there will be a lot of garbage and debris, and there will be a lot of people going to the beach to catch the sea. It is necessary to set up a fence at the outer edge of the selected planting area to prevent foreign objects floating in the sea from affecting the growth of mangrove seedlings in the selected planting area. In order to ensure that the height of the fence is higher than the highest tide level during high tide, the net height is set to 2.0m (higher than the beach surface), and wooden stakes are inserted at intervals of 1m. The length of the wooden stakes is 4m, of which 2m (relative to the elevation of the beach surface) are inserted into the beach mud, and the tail diameter of the wooden stake is more than 5cm. The fence uses a high-quality nylon net with a height of 2.0m and a specification of 30 strands (grid side length 4cm);

[0071] In order to protect the mangrove seedlings from the impact of wind and waves, and to prevent soil loss in the planting patches, wooden stakes and baffles are set up on the outer edge of the selected planting area to form a wind and wave baffle. The baffle stakes are used together with the fence stakes, that is, the lower part is the wind and wave baffle and the upper part is the fence. A wooden stake is set up every 0.5m to fix the wooden board. The fixed wooden stake is 3m long, of which 2m (relative to the elevation of the beach surface) is inserted into the beach mud, and the tail diameter of the wooden stake is more than 10cm. The wooden stakes are all pine stakes. Wooden boards (pine boards) are inserted outside the planting patches. The length, width and thickness of the wooden boards are 2.0mx1.0mx0.025m. The wooden boards and the beach form a 45 degree angle to reduce the force of wind and waves, forming a 0.71m high baffle.

[0072] In order to reduce the risk of wind and wave barriers and fences being damaged by wind and waves, the entire selected planting area is equipped with about 31km of fences and about 55km of wind and wave barriers and fences based on the distribution of waterways, sea-hunting channels and planting patches. They will be dismantled after the maintenance period.

[0073] After the mangroves are planted, they should be tended by dedicated personnel. In particular, the first six months of care and management are the key to forest formation, including the following management items:

[0074] ① Plastic bags, foam and other marine debris and Enteromorpha brought by the tide will damage mangrove seedlings. Therefore, after the tide recedes, the nursery staff should promptly remove the marine debris and Enteromorpha in the selected planting area and properly fix the bamboo poles and straighten the seedlings.

[0075] ②) Carry out beach closure and cultivation for 6 consecutive months, do a good job in replanting missing, dead and diseased plants, investigate the afforestation survival rate in time and replant in time.

[0076] ③ Check the purse seines and wind and wave barriers regularly and repair them promptly if they are damaged.

[0077] ④ Set up necessary management and maintenance channels and strengthen the control of human activities.

[0078] ⑤ Conduct mangrove carbon storage survey and assessment, track and evaluate the carbon storage of existing mangroves and newly restored mangroves, and provide basic data for ecological benefit assessment, etc.

[0079] Furthermore, in the above:

[0080] Planting density xi The method for determining is:

[0081] Get the density-related features of the sub-planting area, where the density-related features include soil quality density xrys ;

[0082] Constructing planting density based on the associated characteristics of mangrove species xi (Usually the number of mangrove species planted per square meter):

[0083] density xi =a×density xrys +b

[0084] Where: a represents soil density xrys The influence weight of , b is a constant term;

[0085] Soil conditions xi The method for determining is:

[0086] Get the soil condition related features of the sub-planting area, where the soil condition related features include soil salinity pgs soil and pH fras soil ;

[0087] Obtain the standard soil salinity Bpgs for the standard planting area soil and standard pH Bfras soil , which is divided into standard soil salinity Bpgs soil and standard pH Bfras soil The grade score intervals are assigned grade values ​​corresponding to the grade score intervals;

[0088] According to the soil salinity pgs soil Corresponding grade values ​​and pH fras soil The corresponding grade values ​​are multiplied to construct soil conditions xi :

[0089] Tidal conditions xi The method for determining is:

[0090] Get the tidal correlation characteristics of the sub-planting area, where the tidal correlation characteristics include the tidal frequency pLks tide and tidal strength qdLfs tide ;

[0091] Get the standard tidal frequency BpLks of the standard planting areatide and standard tidal strength BqdLfs tide , which divides the standard tidal frequency BpLks tide and standard tidal strength BqdLfs tide The grade score intervals are assigned grade values ​​corresponding to the grade score intervals, thereby according to the tidal frequency pLks tide and tidal strength qdLfs tide Determine the corresponding level values ​​respectively, and thus according to the tidal frequency pLks tide and tidal strength qdLfs tide The product of the level values ​​​​constructs the tidal situation tide xi .

[0092] In summary, the present invention reasonably determines the selected planting areas and tolerant mangrove species of mangrove species according to the growth characteristics and interdependence of mangrove species and sub-planting areas, so as to realize the reasonable planning of the spatial layout of mangrove species to simulate the structure of natural mangroves. On this basis, combined with the actual construction needs, a multi-level and multi-sequence combination scheme of mangrove species, as well as the corresponding planting density and configuration ratio are proposed, which can not only improve the ecological environment of the intertidal zone, but also promote the stability and biodiversity of the mangrove plant community. In addition, the method of the present invention is helpful to construct the intertidal zone ecosystem and maintain the stability of the intertidal zone function; at the same time, it can prevent coastal erosion, enhance the flood control capacity of the intertidal zone, and provide a habitat for wild animals, thus having important environmental protection and ecological restoration significance.

[0093] S300, generating planting information based on the determined matching planting area and tolerant mangrove species, determining the area of ​​the matching planting area, and obtaining the regional pre-renovation time of the matching planting area. The regional pre-renovation time refers to the regional cleaning of the matching planting area to ensure that the matching planting area can safely and stably plant mangrove species. It should be noted that different areas will correspond to different regional pre-renovation times, thereby clarifying the regional pre-renovation time of the matching planting area, so that the planting time can be generated immediately based on the time after the regional pre-renovation time, so as to allow the matching planting area to plant mangrove species within the planting time;

[0094] After the mangrove species are planted, the environmental information in the selected planting area and the growth status of the tolerant mangrove species are synchronously collected and monitored through the UAV image acquisition equipment, so as to judge whether the environmental information and the growth status of the tolerant mangrove species meet the expected standards. If they meet, it means that the selected planting area and the tolerant mangrove species are compatible. If not, the acquisition time of the current UAV image acquisition device is determined, and the acquisition time interval threshold is set. The environmental information in the selected planting area and the growth status of the tolerant mangrove species are re-evaluated by the UAV image acquisition device within the acquisition time interval threshold to determine whether they meet the expectations again. If not, the tolerance quality degree of the selected planting area is determined. xi , Planting density of sub-planting area xi , soil conditions xi and tide conditions xi , this tolerance quality level trees xi , Planting density of sub-planting area xi 、Soil conditions xi and tide conditions xi , listed as risk characteristics, so as to avoid the current tolerance quality level trees when selecting the planting area through the associated factor value f′ in the future xi , Planting density of sub-planting area xi 、Soil conditions xi and tide conditions xi , in order to form an adaptation determination for the selected mangrove species and planting areas.

[0095] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
