Water function zone and water resource partition mapping technology

Abstract

The invention relates to a water function zone and water resource partition mapping technology. The water function zone and water resource partition mapping technology includes that overlapping control nodes of the upper and lower ends of each water function zone with a unit planar range according to the upstream and downstream relationship of a drainage basin; listing the corresponding relationship between each water function zone and a calculating unit according to the distribution of the river reach of the water function zone in the calculating unit, and finding out the corresponding relationships between the calculating unit and the confluence and sewage discharge of a plurality of water function zones one by one; determining distribution coefficients; determining the confluence area proportion of the water function zones involved in each calculating unit; arranging the corresponding unit relationships of all the water function zones to form the one-to-many corresponding relationship between the water function zones and the calculating unit. The water function zone and water resource partition mapping technology uses the water function zones and water resource partitions (calculating partitions) capable of being quantified to plan the runoff and water-break processing relationships of the units; each calculating unit is corresponding to one or more water function zones, and meanwhile, each water function zone can run through the corresponding relationship of one or more calculating units to realize the uniformity of two types of corresponding relationships.

Description

technical field [0001] The invention relates to a technology for mapping water function zones and water resource partitions. Background technique [0002] Water function zone is defined as a water function zone that meets the needs of human beings for the rational development, utilization, conservation and protection of water resources, according to the natural conditions of water resources and the status quo of development and utilization, in accordance with the requirements of comprehensive basin planning, water resource protection and economic and social development, and according to its leading The function is to delineate the scope and implement the corresponding water environment quality standards for water areas. The purpose of water function zoning is to coordinate the development, utilization and protection of water resources, the relationship between the whole and the parts, and determine the function and function sequence of the water area according to the natural...

Problems solved by technology

However, the electronic maps and other products currently on the market have only established the line-surface correspondence between water function areas and water resource partitions (water volume simulation units); there is still a lack of method steps for determining the overall correspondence of the watershed.
