海洋牧场选址适宜性评估——以烟台北部海域为例

Suitability assessment of marine ranching site selection—A case study of Yantai northern sea area

  • 摘要: 我国的海洋牧场事业迅速发展,选址问题对于海洋牧场的建设与发展至关重要。本文以全国海洋牧场建设示范之城 —烟台市为例,基于海洋功能区划及其他社会因素,在其北部海域选定A~F 六个海洋牧场拟建区域,选取水深、水动力、底质类型、水质及沉积物质量、叶绿素a、富营养化状况等指标对各拟选区域进行海洋牧场选址适宜性评价。通过计算各拟选区域的海洋物理化学环境综合适宜性指数发现:A区域综合适宜性指数最高、C区域最低,对于整个拟选区域海洋牧场建设的适宜程度来说,有36.88 km2的海域为适宜、625.63 km2的海域为较适宜、318.88 km2的海域为不适宜。在海洋生物环境方面,各拟选海域叶绿素a含量差距较小,但夏季叶绿素a含量均较低;F海域在夏秋季节易发生海水富营养化污染,对海洋牧场的健康运营有一定危害。该研究为烟台市海洋牧场的选址及建设问题提供了依据,也为国内外其他地区海洋牧场的建设问题提供了参考。

     

    Abstract: With the rapid development of marine ranching in China, the location of marine ranching is critical to its construction and development. This paper takes Yantai as an example, which is the demonstration city of marine ranching construction in China. Based on marine functional zoning and other social factors, six proposed areas of marine ranching A to F are selected in the northern sea area of Yantai. Then, the indicators of water depth, hydrodynamics, sediment type, water quality and sediment quality, chlorophyll a, eutrophication status and other indicators were selected to evaluate the suitability of marine ranching sites in each proposed area. By calculating the comprehensive suitability index of marine physicochemical environment for each proposed area, it is found that: the comprehensive suitability index in area A is the highest and that in area C is the lowest. For the suitability of marine ranching construction in the entire proposed area, 36.88 km2 area is the most suitable, 625.63 km2 area is suitable, and 318.88 km2 area is not suitable. In terms of marine biological environment, the difference of chlorophyll a in the proposed sea areas was small, but the content of chlorophyll a was low in summer; area F is prone to seawater eutrophication pollution in summer and autumn, which is harmful to the healthy operation of marine ranching. This study provides support for the site selection and construction of marine ranching in Yantai northern sea area, and also provides a reference for the construction of marine ranching in other regions.
