Ecology-oriented water and soil resource space-time optimal configuration method

Abstract

The invention belongs to the technical field of water and soil resource information processing, and discloses an ecology-oriented water and soil resource space-time optimal configuration method. The method comprises the following steps of establishing an ecology-oriented water and soil resource configuration system by using a gray linear programming method; fusing the multi-source spatial data byadopting a method of analyzing a vector grid, and establishing a water and soil resource allocation model based on multiple spatial scales such as a pixel micro-unit, a basin ecological function partition, a regional administrative planning partition and the like; adopting the cellular automaton for simulating the specific distribution of the quantity ratio of water and soil resources in space. According to the method, the cellular automaton is used for simulating the spatial distribution condition of water and soil resources under multi-objective decision making, and organic combination of water and soil resource quantity matching and spatial distribution is achieved. The method has important practical significance in improving the comprehensive utilization efficiency of water and soil resources and promoting regional ecological safety and sustainable development.

Description

technical field [0001] The invention belongs to the technical field of water and soil resources information processing, and in particular relates to an ecologically oriented water and soil resource space-time optimal allocation method. Background technique [0002] At present, the closest existing technology: traditional water resources planning and utilization believes that freshwater resources are inexhaustible and inexhaustible, completely ignoring the relationship between water resources and the ecological environment system, which directly leads to the degradation of the ecological environment, Biodiversity reduction, river closure and groundwater table decline. At present, the water and land resources allocation system is mainly reflected in the single development and utilization of water resources and land resources, and most of them focus on economic benefits. A more comprehensive and systematic "ecological-oriented" water resources spatiotemporal optimization syste...

Problems solved by technology

The third is that there are many goals for the allocation of water and land resources, including the single and comprehensive maximum of social benefits, economic benefits and ecological environmental benefits. At the same time, there are many indicators used to evaluate each target, and some benefit indicators are not easy to quantify

②The technical difficulty of land and water resource allocation based on time-space scale lies in the fusion of multi-source data

Since water and land resources planning involves complex issues such as multi-objective and multi-constraint models, large-scale and large-scale system optimization solutions, and multiple alternative planning schemes, it is difficult to achieve multi-source data on the temporal and spatial scales only by relying on traditional abstract mathematical models.
