However, there are still many problems as follows: the cooperation never goes deep;the cooperative governance is devoid of necessary system guarantee and information exchange and share platform. We analyse the status quo of cooperation in regional intergovernmental public administration as follows: it integrates the hierarchy power of government; it sponsors the forum for strengthening public administration and deepening cooperation in Beibu Gulf Economic Zone; it accelerates regional transportation system building; it sets up public administration institution; it quickens the pace of innovation of management and system in Beibu Gulf Economic Zone. Finally we put forward the path to construction of regional government cooperative governance so as to promote sustainable regional development as follows: construct the composite regional administrative cooperative governance model; construct the regional administrative network organization governance model; construct regional administrative special-project-based intergovernmental cooperative governance model; construct long-term flexible regional administrative cooperative mechanism.展开更多

There was a decreasing trend in the concentration of nutrients from the north coast to offshore waters of the northern Beibu Gulf, reflecting the influence of inputs from land-based sources. High concentrations of dissolved inorganic nitrogen(DIN) and phosphate(PO 4-P) occurred mainly at Fangchenggang Bay, Qinzhou Bay, and Lianzhou Bay. Four different methods were used to assess eutrophication. The trophic status of the Beibu Gulf was characterized using the single factor, Eutrophication index(EI), Trophic index(TRIX) and Assessment of Estuarine Trophic Status(ASSETS) methods. Based on nutrient concentrations, 73.9% of DIN and 26.7% of PO 4-P samples exceeded the fourth grade Seawater Quality Standard of China. Eutrophication index values varied widely, but higher levels of eutrophication were generally found in bays and estuaries. TRIX values ranged from 2.61 to 7.27, with an average of 4.98, indicating a mesotrophic and moderately productive system. A positive correlation between TRIX and harmful algal species richness and abundance was observed. The ASSETS model evaluates eutrophication status based on a Pressure-State-Response approach, including three main indices: influencing factors, overall eutrophic condition, and future outlook. The Beibu Gulf was graded as moderate using ASSETS. The single factor and Chinese nutrient index methods were considered inadequate for the assessment of trophic status. TRIX can be used as an indicator of trophic state and ASSETS showed good potential to assess eutrophication. The results of TRIX and ASSETS depend on threshold values. To establish these values, further research is required within the northern Beibu Gulf.展开更多

The coastal tourism resource is an important part of marine resources. Coastal tourism has already been one of the fi elds with the fastest developing speed in modern tourism. Qinzhou, as one of the three coastal cities of Beibu Gulf Economic Zone in Guangxi Province, China, is very rich in the coastal tourism resources with greatly potential development. It has been developing rapidly these years. But there are still some problems. Firstly, the author gives an overview to the status of coastal tourism resources in Qinzhou and points out the existing problems; then the other uses the SWOT analysis method to briefl y analyze the advantages, disadvantages, opportunities and challenges for the development of the coastal tourism culture of Qinzhou; fi nally, the paper puts forward suggestions for sustainable development of coastal tourism culture to promote the sustainable development of Qinzhou tourism industry.展开更多
