Analysis of Regional System Couple State in Rapid Developing Coastal Region:A Case Study of Hainan Province

Hainan province is an important tropical agricultural production base in China.In recent years,it has developed very rapidly with the support of China's opening policy.But at present there are many problems restricting the regional sustainable development,such as resources exhaustion and environment pollution.It is an original approach to valuate regional system evolution scientifically based on the system theory,and in this way,many internal characteristics of regional development may be discovered,so we can advance many advices to guide the sustainable running of regional system.Couple degree is an indicator reflecting the interaction relations among many systems or elements and evolution scenarios of the regional system on a spatio-temporal scale in a specific zone.Base on the analysis of system elements' characters and couple mechanism,mathematics models have been made to evaluate the couple degree of regional comprehensive support capacity and regional development consumption level,and have been applied to take a case study with Hainan province from 1995 to 2004.The conclusions are as follows: 1) Both the regional comprehensive support capacity and the regional development consumption level ascended,but fluctuated a little in this period;2) The evolution velocities of the regional comprehensive support capacity system and the regional development consumption level system are not concordant;the former descended from 0.1239 in 1995 to 0.0124 in 2004 gradually,but the latter ascended with an annual velocity of 5.7%;3) The coupling degree of the regional inner system is in the scope of[0°,45°],and it changed very rapidly.Accordingly,the priority to keep the regional system in a good state has been given to make science-developing strategy with the guidance of sustainable development notion.Attention should be paid to the industrial structure optimization and the tropical agriculture base construction.Moreover,eco-agricultural and eco-tourism models and low energy-cost industry production models should be popularized and applied as well.Only by this way,the total resources consumption can be reduced rapidly;and will economy and society develop fast and healthily within the regional capacity ability in Hainan province in the future.
