[0002] With the in-depth promotion of the construction of ecological civilization and the concept of sustainable development, territorial space planning has gradually shifted from the traditional single land use method to a new model that pays more attention to the overall protection of the ecological system and the optimization of the spatial layout. In recent years, spatial information technologies such as remote sensing technology, unmanned aerial vehicle aerial survey, and geographic information system (GIS) have developed rapidly, providing efficient and accurate data support for ecological environment assessment, land use classification, and social and economic statistics. Spatial planning methods centered on the theory of ecological security pattern have gradually emerged, gradually realizing the integration of ecological protection and regional economic and social development, and providing important method support and technical guarantee for the construction of ecological civilization.

[0003] However, there are still many deficiencies in the existing territorial space planning methods: First, existing technologies usually focus on a single ecological factor or simply superimpose ecological environment indicators, making it difficult to comprehensively and systematically reflect the complex interaction between ecological elements in the region, and difficult to effectively identify regional ecological sensitivity, resulting in unclear definition of ecological sensitive areas and inaccurate implementation of ecological protection measures; Second, existing planning methods lack fine spatial division of ecological buffer zones and development zones, with fuzzy buffer zone boundaries and poor connection between the functional layout of the development area and the ecological space, resulting in easy spatial conflicts between ecological protection and economic development, restricting the effective implementation of ecological protection measures; In addition, traditional spatial planning means lack a dynamic optimization and feedback mechanism and cannot monitor and evaluate the implementation effect of the plan in real time, resulting in difficulty in timely adjustment and optimization according to the actual ecological situation after the implementation of the plan, restricting the scientific nature and sustainability of the spatial planning plan. Therefore, there is an urgent need to develop a new type of spatial planning method that comprehensively considers the ecological security pattern and regional development needs, can achieve precise division of ecological functions, reasonable optimization of spatial patterns, and dynamic adjustment, so as to effectively make up for the deficiencies of existing technical methods.

[0022] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following provides a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0023] Example 1, referring to Figure 1 - Figure 2 , which is an embodiment of the present invention, provides an optimization method for territorial spatial planning based on the ecological security pattern, including:

[0024] S1: Obtain regional ecological environment, land use, and socioeconomic data through remote sensing satellite images, unmanned aerial vehicle (UAV) aerial images, and geographic information systems.

[0025] Furthermore, use remote sensing satellite images, UAV aerial data, and geographic information system (GIS) technology to obtain multi-source information data such as the ecological environment status, current land use, population distribution, and economic development level within the research area. Remote sensing satellite image data includes visible light images, multispectral images, and radar images; UAV aerial data is mainly used to obtain high-resolution detailed surface features, such as land cover types, vegetation coverage, and water body distribution; GIS technology is used to integrate various spatial data and attribute data, such as soil type data, topographic and geomorphic data, climate and hydrological data, and socioeconomic statistical data. Perform a series of strict preprocessing on the obtained multi-source data, including spatial registration and image correction, noise reduction processing to remove interference information such as clouds and shadows, and spatio-temporal information fusion processing of data from different sources to ensure the consistency and accuracy of the data. Finally, establish a spatial database with rich spatial information, clear attribute characteristics, and accurate and unified data, providing a solid data foundation for ecological security pattern analysis and spatial planning optimization.

[0026] S2: Based on the characteristics of the ecosystem and regional development needs, carry out ecological sensitivity identification and spatial function zoning. By analyzing elements such as biodiversity, nature reserves, water source conservation areas, and geological disaster areas, delimit ecological sensitive areas and implement protection; according to the ecological disturbance risk and functional requirements, delimit ecological buffer zones, and at the same time identify ecological suitable development areas, and determine the development boundary and construction intensity.

[0027] Furthermore, in combination with the actual needs of the ecological security pattern, considering the multi-dimensional interaction relationship of ecological corridor connectivity, ecological buffer zones, landscape heterogeneity, and ecological function complexity, design the minimum cumulative resistance model expressed as:

[0028]

[0029] The specific sub-functions are as follows:

[0030] (1) The ecological resistance function R(x, y) is expressed as:

[0031] R(x, y) = e (λ·L(x,y)+μ·F(x,y)+θ·W(x,y))

[0032] (2) The ecological connectivity function E c (x, y) is expressed as:

[0033]

[0034] Among them, NCI(x, y) is the landscape node connectivity index, expressed as:

[0035]

[0036] (3) The landscape heterogeneity index function H(x, y) is expressed as:

[0037]

[0038] (4) The ecological buffer function C L (x, y) is expressed as:

[0039] C L (x, y) = ln[1 + ω·(dist(x, y) + δ)]

[0040] (5) The ecological function compensation function B j (S j ) is expressed as:

[0041] B j (S j ) = φ j ·S j τ

[0042] Among them, MCR opt is the optimized ecological minimum cumulative resistance value, reflecting the spatial ecological security cost; K is the total number of all possible ecological corridor paths; the integration interval (x a , x b ) represents the starting and ending ranges of the spatial coordinates from the ecological source area to the target interval; R(x, y) is the ecological resistance function, characterizing the size of the obstacles encountered in the ecological process; E c (x, y) is the ecological connectivity function, expressing the landscape node connection ability; H(x, y) is the landscape heterogeneity index function, characterizing the diversity of the ecological patch composition; C L (x, y) is the ecological buffer function, reflecting the protection effect of the buffer on ecological security; γ is the path resistance cumulative index, greater than 0; J is the number of types of ecological function compensation; β jis the compensation adjustment coefficient of the ecological compensation function; B j (S j ) is the ecological function compensation function, S j is the area of the j-th ecological function; λ, μ, θ are the adjustment coefficients of the ecological resistance index; L(x, y) represents the land use type index; F(x, y) represents the land surface cover index; W(x, y) represents the hydrological sensitivity index; ρ, η are the adjustment parameters in the connectivity function; NCI(x, y) is the landscape node connectivity index; A p is the area of the p-th ecological node; A total is the total area; d p (x, y) is the spatial Euclidean distance between nodes; α is the node connectivity attenuation coefficient; p z (x, y) is the area proportion of the z-th landscape type in the unit; Z is the number of landscape types; ω, δ are the adjustment parameter and distance offset coefficient of the buffer function respectively; dist(x, y) is the spatial distance between the calculation unit and the ecological source area; φ j , τ are the ecological function compensation coefficient and area index respectively, and all the above parameters are independent of each other and have no repeated expressions.

[0043] MCR opt The theoretical value range of MCR is positive real numbers greater than 0. The smaller it is, the lower the ecological security protection cost, the higher the effectiveness of the ecological corridor, and the closer it is to the ideal pattern of ecological security. When the value range approaches infinity, it indicates that the ecological protection is difficult, the regional ecological risk is high, the ecological environment is fragile, and ecological planning and protection intervention measures are urgently needed.

[0044] It should be noted that based on the constructed ecological security pattern framework and combined with the current ecological environment status in the region, areas with rich biodiversity, concentrated distribution of rare species, nature reserves, wetland reserves, drinking water source protection areas, areas with prominent water conservation functions, areas with fragile ecological environment backgrounds, and areas prone to geological disasters are selected for comprehensive analysis to clarify the spatial scope and boundaries of the ecological sensitive areas. Strict protection and control measures should be implemented in the ecological sensitive areas, including prohibiting all development behaviors that may damage the stability of the ecosystem, restricting human activity interference, giving priority to arranging ecological restoration projects, and establishing a long-term ecological monitoring and protection system to ensure the long-term ecological security of the ecological sensitive areas.

[0045] Secondly, scientifically delimit the ecological buffer zones outside the ecologically sensitive areas. The delimitation of the ecological buffer zones mainly extends outward from the outer boundaries of the ecologically sensitive areas, and the specific width varies according to the types of ecosystems, sensitivity levels, and requirements of regional ecological service functions. Generally, an appropriate distance can be set according to the core protection needs of the ecologically sensitive areas. Low-intensity and eco-friendly activities are advocated in the ecological buffer zones, such as ecological agriculture, eco-tourism, forest cultivation, grassland restoration, soil and water conservation projects, ecological greening construction, etc. At the same time, clear guidelines for ecological protection and construction should be formulated in the ecological buffer zones to reduce the potential impact on the ecological environment of the sensitive areas and build an effective protection barrier for the ecologically sensitive areas.

[0046] Finally, when delimiting the suitable areas for land development, comprehensively consider the regional economic development needs and the development potential of land resources. Prioritize the selection of areas with good ecological environment background conditions, obvious location advantages, convenient transportation, and relatively small ecological impacts as the suitable areas for land development, and clarify that this area is the main spatial carrier for future urban and rural construction, infrastructure layout, industrial park development, and agricultural production layout. Formulate clear control standards for development intensity and scale, plan a centralized construction mode, and avoid the scattered and disorderly expansion of land development. At the same time, strengthen ecological protection measures in the suitable areas for land development, such as arranging ecological green spaces, building ecological corridors and ecological landscape nodes, reducing the negative ecological effects brought by development and construction, and ensuring the coordinated unity of economic and social development and ecological environmental protection goals.

[0047] S3: Establish an optimization mechanism for spatial planning, coordinate the spatial relationships among ecological corridors, buffer zones, and development zones, formulate plans for the alignment, width, and structural zoning of ecological corridors, plan the functional layout and ecological green space system within the development zones, build a green transportation and infrastructure network, and introduce dynamic monitoring, scenario simulation, and benefit assessment mechanisms to continuously optimize the planning scheme.

[0048] Furthermore, based on the ecological security pattern framework and the results of ecological sensitivity analysis, combined with the actual natural resource conditions, environmental characteristics, economic development needs, and social development strategies of the study area, formulate a detailed and specific spatial planning optimization plan. First, based on the positions of the ecological source areas and ecological corridors identified in the early stage, clarify the specific alignment, spatial location, necessary width, and structural composition of the ecological corridors to ensure the integrity and continuity of the ecological functions within the ecosystem and across regions. Specifically, the migration routes of species, ecological flow requirements, and natural environmental conditions inside and outside the ecological corridors should be comprehensively considered to clarify the core protection areas, buffer zones, and outer collaborative areas of the ecological corridors, ensuring the functionality and effectiveness of the ecological corridors.

[0049] Secondly, precisely determine the scope and layout plan of the ecological buffer zone. The ecological buffer zone should be appropriately extended according to the ecological sensitivity outside the ecological sensitive area to form a protection barrier for the ecological sensitive area. During the specific planning process, it is necessary to clarify the land use planning within the ecological buffer zone, such as ecological green belts, construction of artificial forests, soil and water conservation measures, ecological agriculture areas, and low-impact development projects such as ecological tourism and education experience facilities, to strengthen the ecological protection role of the ecological buffer zone and reduce the potential negative impacts of human activities on the ecological sensitive area.

[0050] Finally, for the suitable areas for land development, elaborate on the spatial layout of development and construction. Define the development boundaries of this area, avoid disorderly expansion and scattered development, and rationally layout functional spaces such as urban and rural residential areas, industrial parks, commercial service areas, and transportation hubs. When planning development and construction projects, implement an intensive and ecological development model, strengthen the supporting construction of infrastructure, layout an ecological green space system, build a regional green transportation network, and promote the efficient and rational use of land resources, ultimately achieving the coordination of regional economic and social development and ecological security goals.

[0051] After the optimization of the spatial planning scheme is completed, conduct scenario prediction and benefit assessment analysis before implementation, which specifically includes three aspects: ecological and environmental benefits, economic and social benefits, and comprehensive sustainability analysis. First, use scenario simulation technology to evaluate the possible ecological and environmental changes after the implementation of the spatial planning, including the effectiveness of biodiversity protection, soil and water conservation effects, improvement of ecosystem service functions, and changing trends of regional ecological risks, etc., to ensure the effective realization of the ecological goals of the planning scheme.

[0052] Secondly, conduct economic and social benefit analysis, evaluate the contributions of the planning implementation to aspects such as regional economic development, improvement of residents' living standards, creation of employment opportunities, optimization of industrial structure, and improvement of social service facilities, to ensure that the actual needs of economic and social development are met and coordinated with the ecological protection goals.

[0053] Regarding the ecological risks, spatial conflicts, and negative effects that may be identified during the scenario simulation and benefit analysis process, formulate corresponding ecological protection and risk prevention measures in advance, optimize the specific spatial layout and construction projects, put forward clear planning adjustment suggestions, and reduce the uncertainties and ecological risks that may occur during the implementation process.

[0054] Finally, establish a dynamic monitoring and feedback evaluation system to regularly monitor and evaluate the actual effects after the implementation of the plan. Continuously track and monitor the stability of the ecological security pattern, the change trend of biodiversity, the protection effectiveness of ecological sensitive areas and buffer zones, the intensity and layout rationality of land development, and the economic and social development effects. According to the actual monitoring feedback results, adjust and revise the spatial planning scheme in a timely manner to dynamically adapt to the new situations and new demands of regional ecological environment protection and social and economic development, and achieve the dynamic optimization of the spatial planning scheme.

[0055] Example 2, an embodiment of the present invention, provides a method for optimizing the national territorial space planning based on the ecological security pattern. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through economic benefit calculation and simulation experiments.

[0056] First, select typical ecologically sensitive areas for experiments, covering nature reserves, wetland reserves and the urban-rural fringe areas. First, use remote sensing satellite images to obtain large-scale ecological information, including vegetation coverage and the change trend of multi-spectral vegetation indices; use drones for aerial photography to supplement high-precision surface details, such as local vegetation distribution, water area boundaries, terrain changes, etc.; at the same time, integrate soil types, geological disaster risks, and economic and social development index data through the geographical information system. Perform strict spatial registration, image correction and denoising on the collected data, remove cloud cover and shadow interference information, and ensure the consistency and accuracy of the fusion of data from different sources. Subsequently, build a complete data platform based on the fused data to lay a data foundation for subsequent experiments. On this basis, according to the optimized ecological security model proposed by the present invention, combined with the actual situations of ecological corridors, buffer zones and functional compensation areas, through comparative experiments, respectively adopt the traditional ecological planning method and the method of the present invention to clarify the changes in key indicators such as ecological resistance, landscape connectivity, and landscape heterogeneity in the planning area, and verify the effectiveness of the optimized model.

[0057] Table 1 Experimental data table

[0058]

[0059] Through the analysis of the above experimental data, it can be clearly found that the optimization method proposed by the present invention significantly outperforms the traditional method in terms of various parameters. For example, in terms of the ecological resistance index, the optimized ecological resistance index is significantly reduced, which indicates that the method proposed by the present invention can effectively reduce the spatial resistance in the ecological process, enhance the connection ability between ecological function areas, promote species migration and ecological flow, and significantly improve the ecological security effect. The improvement in the landscape connectivity index is also very significant. The index has increased significantly from 0.59 and 0.65 of the traditional method to 0.79 and 0.84, indicating that the functional connection ability between ecological nodes is stronger, the effectiveness of ecological corridors is higher, and the ability to guarantee regional ecological security is significantly enhanced. The increase in the landscape heterogeneity index further reflects the advantages of the present invention in promoting the stability of the ecosystem and ecological service functions, and effectively improves the recovery and adaptation ability of the ecosystem in the face of external disturbances. In addition, the ecological buffer protection efficiency index has increased from 0.47 and 0.51 of the traditional method to 0.70 and 0.75, fully indicating that the optimized method can more effectively alleviate the impact of external disturbances on sensitive ecological areas and establish a more solid ecological protection barrier. In terms of ecological function compensation, the area of the ecological function compensation area clearly demarcated by the optimized method has increased significantly, from 10.9 and 12.5 km 2 to 14.6 and 15.8 km 2 , and the ecological function compensation is more accurate and effective, greatly improving the pertinence of regional ecological protection and restoration. Generally speaking, the cumulative ecological security cost index after optimization has been significantly reduced, from the traditional 6.4 and 6.9 to 3.8 and 4.2, highlighting the superiority of the method of the present invention in coordinating ecological protection and regional economic development, proving the creativity and practicality of the present invention in the field of ecological space planning, and having broad application prospects

The spatial planning scheme formulation and implementation adjustment module is used to divide ecological sensitive areas, buffer areas, and land development suitable areas, and perform scenario prediction and evaluation before implementation and dynamic monitoring and feedback in the later stage.
