Embodiment Construction

[0094] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0095] The Xiangxi River Basin selected by the present invention is located in Hubei Province, China, with geographic coordinates between 30°57'N, 31°34'N and 10°25'E, 111°06'E, including Zhaojun Town and Xiakou Town , Gufu Town, Guizhou Town and Nanyang Town. The Xiangxi River originates from Shennongjia, with a drainage area of ​​3099km 2 , there are three tributaries of Gufu River, Gaolan River and Jiuchong River. The basin is rich in phosphate rock and is the third largest phosphorus-producing area in China. The Xiangxi River basin has a subtropical monsoon continental climate with abundant rainfall, and the rainy period is from May to September. The farmland in the watershed is distributed along the river, and the main soil types are yellow brown soil, lime soil and purple soil. The main crops are rice, wheat, corn, potatoes, citrus and...

Abstract

The invention discloses a nonlinear agricultural non-point source pollution control method. The method comprises the steps that data are collected, a watershed hydrologic model is established, verification is conducted, an interactive algorithm is adopted in a nonlinear non-point source pollution control model, a submodel is split, an upper bound submodel and a lower bound submodel are subjected to linearized solution, 11 risk situations are defined by changing the risk level rho, a linear equation is solved to acquire the agricultural optimal planting area (please see the specifications for the formula) under the 11 risk situations and the optimal dumping right (please see the specifications for the formula) obtained through transaction in each agricultural area, and the comprehensive degree of satisfaction (please see the specifications for the formula) of environment pollution under the 11 risk situations is further acquired. According to the method, the indefinite information characteristics of random numbers, interval numbers, fuzzy numbers and the like are comprehensively considered, the production plan can be helped to be adjusted for a researched river basin, and emission is made to meet the environment requirement.

Description

technical field [0001] The invention belongs to the field of water quality management, and in particular relates to a method for controlling non-point source pollution in non-linear agriculture. Background technique [0002] Agriculture is the pillar industry of the national economy and people's livelihood. With the growth of population, the demand for food is increasing, and the output of agricultural products is increasing rapidly, while environmental problems also follow. Agricultural non-point source pollution load is large, the pollution area is wide, and it is difficult to control. In order to increase food production, a large number of chemical fertilizers and pesticides are applied to farmland. According to statistics, in 2012, 57 million tons of chemical fertilizers were put into farmland in China. Under the influence of rainfall and topography, these substances easily flow into water bodies with surface runoff and soil erosion, causing serious ecological damage t...
