| Abstract: | Introduction The combination of ocean ranch and offshore wind power is a typical case of the efficient integrated development of modern agriculture and new energy industry. This paper makes a preliminary discussion on the feasibility of the ecological development of "offshore wind power + ocean ranch" in Yangjiang, Guangdong, which responding to the national policy of "three-dimensional use of sea space and maximum utilization of resources" and relieving the supply pressure of aquatic resources in port waters. Method According to the methods of monitoring and analysis of water and waste water and the specifications for marine monitoring, the chlorophyll α and primary productivity as well as the species of marine organisms in offshore wind power area of China Three Gorges Corporation in Yangjiang were counted and analyzed by means of ultraviolet visible spectrophotometer, stereomicroscope, biomicroscope, etc. Result It showed that the average value of chlorophyll α content was 1.79 mg / m3 in the surveyed sea area, the average value of primary productivity was 353.05 mg·C/(m2·d). Besides, There are 4 phyla and 77 species of phytoplankton, 11 phyla and 76 species of zooplankton, 5 phyla and 31 species of macrobenthos, 5 phyla and 43 species of intertidal organisms, and 3 phyla and 37 species of nekton. Conclusion The sea area of the offshore wind power has high primary productivity, which is also rich in phytoplankton and zooplankton, large benthic organisms, intertidal organisms, nekton, etc. Thus, it has ecological foundation and advantages of the integrated development of "offshore wind power + ocean ranch", and also has great potential for fishery resources and the feasibility of ocean ranch construction. |
