Abstract

The invention provides a watershed unit water consumption division method based on geographic information data. The watershed unit water consumption division method comprises the following steps: S1, inputting the geographic information data; S2, cutting the raster data: extracting Polycon data of each region, and performing mask cutting operation on the land utilization raster data and the population density raster data; respectively calculating the population proportion of each drainage basin in the administrative region and the utilization area proportion of each type of land; S3, inputting statistical data: inputting urban and rural demographic data and various water consumption data of an administrative region; S4, dividing water consumption: calculating the current urban population and rural population of each drainage basin; and calculating each water consumption of each drainage basin in the administrative region so as to divide the water consumption according to drainage basin units. The invention provides the watershed unit water consumption division method based on geographic information data, and solves the problems that a main means for measuring and calculating the water consumption of administrative regions in watersheds at present is an empirical method, and a universal method is not formed yet.

Description

Technical field

[0001] The present invention relates to the field of water resources management, and more particularly to a water volume division method for a ribbon unit based on geographic information data.Background technique

[0002] Water distribution can effectively promote the improvement of water resources utilization efficiency, in the formulation of water distribution programs, need to consider the current situation of water in the basin of the administrative area in the basin. At present, my country is only statistics on the water volume of the large basin, and the water resources publication of the relevant basin is announced, while the water volume of the administrative units in the small basin is not announced. Therefore, in the development of the water quantity distribution scheme in the small watershed, it is necessary to reasonably measure the amount of water in the basin of the basin, as the basis for the water distribution scheme. At present, the main means of calculati...
