Abstract:As one of the important water resources, the water quality management of ponds is very important for ecological protection and sustainable development of aquaculture. However, traditional water quality monitoring methods are limited by sparse sampling points and periodic measurements, and cannot provide real-time and high-resolution water quality information. The purpose of this paper is to develop a water quality monitoring visualization system based on UAV multispectral technology. Firstly, a drone equipped with a multi-spectral sensor is used to regularly fly over the target pond to collect multi-spectral data of the water body to analyze the water quality. Then, the management of water environment data is realized through WebGIS technology, which provides strong technical support for aquaculture and environmental protection. The results showed that: (1) UAV multispectral technology could be applied to pond water quality monitoring, and could quickly respond to water quality changes, which was helpful to improve the efficiency of pond aquaculture management; (2) The spatial difference of water quality in Nanquan pond was small, and the time difference was obvious, and the water quality status was generally better from March to April, and the water quality status from May to August had a tendency to deteriorate. (3) It is recommended to strengthen pond management in summer to reduce the pollution of aquaculture water quality. This research provides new tools and methods for water quality management and ecological conservation, which is expected to be replicated and demonstrated in the aquaculture industry.
