Wu, H.L., 2020. Protection of water resources in Dongsha Scenic Area of south sea. In: Guido Aldana, P.A. and Kantamaneni, K. (eds.), Advances in Water Resources, Coastal Management, and Marine Science Technology. Journal of Coastal Research, Special Issue No. 104, pp. 1–5. Coconut Creek (Florida), ISSN 0749-0208.

As the scenic spot of Dongsha sea area in Nanhai Sea, it is faced with the situation of coexistence of opportunity and challenge as the scenic spot strategic water source. Firstly, the paper constructs the three objective functions of economic, social and environmental benefits of Dongsha Scenic Area in Nanhai Sea, taking the available water supply, water demand, comprehensive evaluation index of water environment, total water quality and water balance as the constraint conditions, taking the ecological environment benefit, economic and social benefit as the optimization goal to construct the multi-objective coupling model of water resources protection in Dongsha Scenic Area in Nanhai Sea, and solves the multi-objective coupling model of water resources protection by particle swarm optimization algorithm. The results show that the total value of scenic resources in Dongsha Sea area of Nanhai Sea is 80 points. After 2014, the comprehensive development level of the water resources eco-environment system in the Dongsha Sea Area of the Nanhai Sea was above 0, and maintained an upward trend. The comprehensive development level is rising rapidly, and the reduction of main pollutants in the water resource ecological environment in the Dongsha Sea Area of the Nanhai Sea is controlled.
