Real-time non-point source pollution monitoring system based on slope furrow distribution

Abstract

The invention discloses a real-time non-point source pollution monitoring system based on slope furrow distribution. The system comprises a rainfall monitoring sub system (10) for monitoring rainfallof an experimental plot and the rainfall process, a flow monitoring sub system (20) for monitoring the production flow of the experimental plot, a runoff sampling sub system (30) for sampling a flow outlet of the experimental plot, a soil water sampling sub system (40) for sampling soil water of the experimental plot, a non-point source pollution monitoring sub system (50) for monitoring a non-point source pollution index, a furrow elevation monitoring sub system (60) for monitoring the height and depth changes of a furrow, a control sub system (70) for controlling the sub systems and acquiring and processing data of the sub systems and a power supply system (80) for providing power supply to the sub systems, wherein the non-point source pollution monitoring sub system (50) is connected tothe runoff sampling sub system (30) and the soil water sampling sub system (40) to acquire the sample to monitor the non-point source pollution index.

Description

technical field [0001] The invention relates to the monitoring of agricultural non-point source pollution, and more specifically, to a real-time monitoring system for non-point source pollution based on the layout of slopes, ridges and ditches. Background technique [0002] my country's existing slope farmland area is 359 million mu, of which 97% are distributed in water erosion areas; the average annual soil loss of slope farmland is 1.415 billion tons, accounting for about 1 / 3 of the total soil loss in the country. Ridge and furrow farming changes the micro-geomorphological characteristics of slope farmland units, which in turn affects the rainfall and runoff characteristics of slope farmland and the loss process of chemical fertilizers and pesticides. However, there is currently a lack of real-time monitoring system for non-point source pollution on slope farmland. Contents of the invention [0003] The purpose of the present invention is to provide a real-time monitori...
