广东海水养殖业空间扩散特征与发展对策研究

A Study on the Characteristics of Spatial Diffusion and Measures of Development of the Mariculture Industry in Guangdong Province

广东海水养殖业空间扩散有三个重要特征:从珠三角向粤东、粤西扩散,粤西成为全省海水养殖业发展的中心;形成了对虾和海藻养殖集聚区;从滩涂向陆基、浅海水域扩散。当前广东海水养殖业受到海水质量下降、技术落后、基础设施不完善等因素限制。促进广东海水养殖业向陆基和浅海深水区扩散、正确引导海水养殖集聚区发展,需要从加快工厂化养殖和深水网箱养殖技术创新力度、加大政策支持力度、加强海洋环境保护、加强基础设施建设等方面着手。

There are three important characteristics in the process of spatial diffusion of mariculture industry in Guangdong Province. First, the diffusion starts from the Pearl River Delta towards the east and west Guangdong areas, and finally the west Guangdong area has become the center of the mariculture industry in Guangdong. Second, the industrial agglomeration area of the prawn and algae has been established. And third, the diffusion extends from the beach to the land-based and shallow seawater areas. Nowadays, due to the limitations of the worsening seawater, backward techniques, inadequate infrastructure and so on, the development of mariculture industry in Guangdong Province must extend to the land-based and shallow seawater areas along with the wise guidance of the development of mariculture industrial agglomeration areas, which involve speeding up the technical innovation of the industrial aquaculture and cage breeding in deep water, strengthening the policy support, reinforcing the protection of marine ecological environment, perfecting the infrastructure and so on.
