Abstract

The invention discloses a water data discretization method for setting a weight based on a BP network and a Gini coefficient. The water data discretization method comprises the steps that a basic computing unit is acquired; spatial element data sets of the basic computing unit and an administrative unit are acquired; a quota method is adopted to supplement domestic water and industrial water, and a correlation factor apportion method is adopted to supplement ecological environment water consumption; a Gini coefficient method is adopted to determine a weight coefficient in an ecological environment water consumption computational formula; a discretization predicating result on the basic computing unit is obtained through analog computation; the result is corrected; step-by-step summarizing is carried out according to the attributes of water resource zones of the basic computing unit to obtain corresponding water data. According to the water data discretization method for setting the weight based on the BP network and the Gini coefficient, the economic society and water data of each level of water resource zone in the whole country can be obtained, and integrated water resource management is facilitated.

Description

technical field [0001] The invention relates to the field of water conservancy science and technology, in particular to a water-use data discretization method based on a BP network and a fixed weight of the Gini coefficient. Background technique [0002] Economic and social water use data are mainly collected from administrative units whose boundaries do not coincide with those of water resource areas, making it very difficult to obtain data on water use in water resource areas. The existing economic and social water use data still have problems such as difficulty in sharing, difficulty in statistics and diversity of statistical data. The use of computer technology to obtain economic and social water use data in water resource areas is very important for improving the data base of water resources to support the unified management of water resources administrative regions and river basins and to reduce the input of human census. [0003] Water use refers to the behavior of u...
