Description

Technical Field

[0001] The present application relates to the field of eco-hydrological protection and management technology, and in particular to a method, equipment, medium and product for stabilizing and appropriately coordinating the distribution of mountains, waters, forests, fields, lakes, grasslands and sands in a watershed. Background Art

[0002] Existing ecological protection and governance technologies typically target single ecosystems, such as wetlands, forests, and grasslands, lacking a comprehensive, holistic, and systematic approach to watershed management. This decentralized governance model struggles to coordinate the dynamic balance among multiple elements within a watershed, including mountains, water, forests, fields, lakes, grasslands, and sand. This results in limited improvements in ecosystem function and low resource utilization efficiency.

[0003] In the cold and arid northern regions, the dual pressures of water scarcity and a fragile ecological environment complicate the interplay between multiple factors within the basin. Water shortages limit vegetation recovery, while vegetation degradation exacerbates soil erosion and river siltation, further weakening regional ecological functions and soil and water conservation capacity. Existing technologies are unable to achieve a stable and optimal coordination of these multiple factors in terms of spatial distribution and functional effects.

[0004] In recent years, although the integrated management of mountains, rivers, forests, farmlands, lakes, grasslands and deserts has achieved certain results, these technical means are mostly concentrated on local management, failing to achieve overall optimization and dynamic coordination of multiple factors at the basin scale, and it is difficult to meet the long-term stability and suitability needs of complex basin ecosystems.

The multi-objective optimization model for inland river basins is a nonlinear multi-objective dynamic programming model based on the benign interactive relationship between ecology and hydrology.

[0048] The land use allocation variable is expressed as: X ij |i=1,2,…,n;j=1,2,…,7;water resource allocation variable is expressed as: W ij |i=1,2,…,n;j=1,2,…,7;The land area allocation variable is expressed as: A ij |i=1,2,…,n;j=1,2,…,7;where X ij Indicates whether the i-th area is allocated to the j-th use, X ij =1 means allocation, X ij =0 means no allocation, j=1,2,3,4,5,6,7 corresponds to the seven uses of mountain, water, forest, field, lake, grass, and sand; W ij A represents the amount of water resources allocated to the jth purpose in the i-th region; ij represents the land area allocated to the jth use in the i-th region.

[0054] The technical solution of this application is described below with a specific embodiment:

[0055] The method for stable and appropriate coordination of mountains, waters, forests, farmlands, lakes, grasses, and sands in a watershed provided by this application is a stable and appropriate coordination technology that takes water resources as the core line and coordinates multiple elements (i.e., mountains, waters, forests, farmlands, lakes, grasses, sands, etc.) in the watershed. This technology breaks through the bottleneck of existing technologies from the perspective of spatial distribution and functional synergy, achieves functional improvement of the watershed ecosystem and maximization of resource benefits, and provides technical support for regional ecological security and sustainable development. This application constructs a nonlinear-multi-objective dynamic programming model based on the benign interactive relationship between eco-hydrology, combines constraints such as water resources, land area, socio-economic needs, hydrological functions, and ecological functions, with the goal of optimizing eco-hydrological functions, improving economic and social benefits, and maximizing resource and environmental utilization. Through a multi-objective optimization method, it coordinates the functional allocation and dynamic coordination of ecological elements such as mountains, waters, forests, farmlands, lakes, grasses, and sands, fully reflecting the high correlation between natural and human factors. This application aims to achieve a stable and appropriate coordination of mountain, water, forest, field, lake, grass and sand elements, integrate and construct ecological protection, construction and governance technologies with the characteristics of a living community, and provide a systematic solution for the sustainable development of the basin.

[0056] The method for stabilizing and appropriately coordinating the watershed's mountains, waters, forests, farmlands, lakes, grasslands, and sands provided in this application includes the following steps (1) to (4):

[0057] (1) Basin grid processing:

[0058] The study area is gridded, and the basin is divided into n study units. Based on remote sensing imagery and GIS technology, the basin is divided into regular grids (e.g., 1 km × 1 km) or irregular grids (e.g., based on topographic units) according to spatial characteristics. Each grid unit (i.e., cell) is numbered i.

[0059] Among them, the study area refers to the area containing the watershed and its constituent elements (mountains, water, forests, fields, lakes, grass, and sand). The study area is gridded, and the watershed is divided into n research units (i.e., grid units). It is not divided and calculated only for the watershed part, but the entire study area (including the watershed and its internal mountains, water, forests, fields, lakes, grass, sand and other elements) is gridded. Through this gridding process, the present application can collect data, analyze and optimize the configuration of multiple elements in each grid unit. The calculation results of each grid unit not only take into account the hydrological characteristics of the watershed, but also comprehensively consider the spatial distribution and functional synergy of other ecological elements. Therefore, through the optimal configuration of all grid units, the final stable and suitable coordination results of the watershed mountains, waters, forests, fields, lakes, grasses and sands are based on a comprehensive analysis of the entire study area, rather than just for the watershed part.

[0060] (2) Collection of basic data of the watershed:

In actual applications, the value of α can be flexibly adjusted based on specific data and model requirements:

[0137] 1. Preliminary estimate:

[0138] Based on the regional water resource supply and demand, the value of α is preliminarily estimated. For example, α = 1 can be set as the initial value, indicating a balance between supply and demand.

[0156] (IV) Solution and optimization:

[0157] In order to achieve the optimal configuration of mountains, rivers, forests, farmlands, lakes, grasslands and sand in the watershed, the solution and optimization steps of this application are specifically divided into the following stages:

[0158] (1) Initialization and preprocessing:

[0159] ① Model parameter setting: determine the weight coefficient of the objective function; set the initial conditions, including the ecological capacity of the watershed, the total land area, the total amount of water resources, etc.; define the upper and lower limits of the decision variables X ij ∈{0,1},W ij >0,A ij >0.

[0160] Among them, the objective function weight coefficient refers to the formula α in k and α l ; Initial conditions refer to the basic parameters and constraints that need to be set before the model runs, including: Formula (2) Hy k 、Ec l , formula (3)gr ij , sc ij, formula (4)wq ij , formula (5)co ijw ,q ijw , formula (6)Cost sum , formula (8)γ ij 、S ij , formula (9)θ ij 、R ij , formula (12)δ ij , Q(t), formula (13)Q HS (ij), formula (15) Formula (16) S ij 、 Formula (17) Formula (18) Formula (20)Ir ijz 、MinIr eco (ij), MinIr prod (ij), formula (21)η ijz , formula (22)SX ij 、GX ij , EP i ET ij , formula (23)I ij , O ij , Formula (24) K k' , Formula (25) K k .

[0161] ② Data gridding: Divide the watershed into small grid units (such as 1km 2 ), with each unit acting as an independent decision-making unit. Topographic, ecological, and hydrological characteristics are input into each grid cell of the watershed division as the basis for decision-making in the optimization model. Data is obtained through the following methods:

[0162] Topographic data: Remote sensing images (such as satellites and drones) and GIS technology are used to generate digital elevation models (DEMs).

[0163] Ecological data: remote sensing inversion (such as NDVI vegetation index) combined with ground surveys (biodiversity, wetland area).

[0164] Hydrological data: meteorological / hydrological station observations, satellite precipitation products (such as GPM) and hydrological model simulations (such as SWAT).

[0165] (2) Algorithm design and parameter configuration:

[0166] To solve the nonlinear multi-objective dynamic programming model, this application uses a combination of the following optimization algorithms:

[0167] ①Genetic Algorithm (GA) configuration:

[0168] Encoding method: X ij 、W ij 、A ij are grouped into chromosomes. For example, each chromosome contains: a binary part X ij (7 bits, indicating 7 uses); real number part W ij and A ij (continuous value).

[0169] Parameter settings: Set the population size to 200; set the crossover rate to 0.8 (two-point crossover); set the mutation rate to 0.05 (bit flip mutation).

[0170] ②Particle Swarm Optimization (PSO) configuration:

[0171] Particle representation: Each particle represents a set of solutions (X ij 、W ij 、A ij ), real number encoding.

[0172] Parameter settings: Set the number of particles to 100; set the inertia weight to 0.9 (linearly decreasing); set the learning factor c1 = c2 = 2.0.

[0173] ③ Hybrid algorithm strategy:

[0174] Phase 1 (GA global search): Run GA for 100 generations to generate diverse candidate solutions.

[0175] Phase 2 (PSO local optimization): The first 50 solutions are selected from the Pareto frontier of GA as the initial particle swarm of PSO, and 50 generations are iterated for fine-tuning.

[0176] (3) Iterative solution and optimization:

[0177] ① Parameter initialization: Randomly generate an initial solution set (such as 100 sets of X ij 、W ij 、A ij ), ensuring that the binary and area constraints are met.

[0178] ② Iterative solution: Evaluate the objective function value of each solution; generate a new solution by updating the speed and position in the optimization; check whether the solution meets all constraints. If not, correct it through the penalty function.

[0179] ③ Convergence criterion: When the change of the objective function is less than a threshold (such as 0.1%), or when the maximum number of iterations is reached (such as 500 times), stop the optimization.

[0180] (4) Result output and verification:

[0181] ① Extract the optimal solution: extract the optimized optimal solution set and output the land use allocation (X ij ), water resources allocation (W ij ) and area allocation (A ij ).

[0182] Among them, the relationship between land use allocation, water resource allocation and area allocation (i.e. land area allocation) and the stable and appropriate coordination of mountains, rivers, forests, farmlands, lakes, grasslands and sands in the basin is: land use, water resources and area allocation are specific technical means, and the refined allocation of space and resources is achieved through scientific decision-making. The stable and appropriate coordination of mountains, rivers, forests, farmlands, lakes, grasslands and sands in the basin is the ultimate goal, which is reflected in the stability of the ecosystem, the efficiency of resource utilization, and the sustainability of the social economy. The dynamic coordination of the three is the key to achieving the goal: land use determines the functional positioning (such as forest land conserving water sources), water resource allocation supports the realization of functions (such as forest land requires a certain amount of precipitation or irrigation), and area allocation controls the scale of functions (such as the forest area must meet the ecological threshold).

[0183] ②Verify constraint compliance: Check whether all constraints are met.

[0184] ③Uncertainty analysis: Using Monte Carlo simulation, randomly perturb the input data (such as ±10% precipitation change) to evaluate the robustness of the optimization results.

[0185] Monte Carlo simulation quantifies the potential impact of random perturbations on input parameters on the optimized allocation results, ensuring that stable coordination of mountains, rivers, forests, farmlands, lakes, grasslands and sands can still be achieved under climate change.

[0186] This application uses innovative technologies for stabilizing and optimizing the distribution of mountains, rivers, forests, farmlands, lakes, grasslands, and sand in the watershed, taking into account the dynamic balance and coordinated optimization of multiple factors within the watershed, to achieve the following results:

[0187] (1) Improving the overall ecological function of the watershed: This application focuses on optimizing the eco-hydrological function and, through a multi-objective dynamic programming model, achieves a stable and appropriate coordination of elements such as mountains, water, forests, fields, lakes, grass, and sand. This effectively improves the stability, resilience, and sustainability of the overall ecosystem in the watershed.

[0188] (2) Optimizing resource utilization efficiency: By coordinating the rational allocation of water and land resources, this application significantly improves resource utilization efficiency. In water resource management, it achieves improved water use efficiency and optimizes the spatial allocation of water resources, meeting the multiple needs of ecological protection and socioeconomic development.

[0189] (3) Constructing a regional ecological security pattern: This application constructs a security pattern for the watershed ecosystem through the coordinated optimization of spatial distribution and functions. This application achieves the benign regulation of the hydrological cycle, the gradient optimization of vegetation restoration, and the stabilization of the ecological water levels of wetlands, rivers, and lakes, significantly enhancing the region's ability to resist extreme climate events.
