Present Situation of Land Use and Its Problems in Coastal Zone of Hainan

In this paper the coastal zone to be studied is defined as the area along the shoreline at mean high tide level with a width of 2 km. The present situation of land use of the coastal zone and its problems are analyzed. The results show that:1) there are 228 166.44 hm2 of land resources in 12 coastal cities and counties, accounting for 6.63% of the total of the province; 2) both coastal land area and the farmland area in Wenchang rank first on the list of the 12 coastal cities and counties,while Sanya has the largest construction land area in coastal zone,Haikou the second; 3) the density of the construction land in coastal zone is high,which is 4.5 times the average of the province; 4) the land utilization efficiency of coastal zone is high,but contradiction between man and land becomes more and more prominent.And the land use structure needs to be optimized; 5) the intensive land use of coastal zone has led to obviously ecological degeneration, and this is particularly prominent in Wenchang,Wanning and Haikou.Aiming at those problems,the paper brings forward some countermeasures or suggestions for coastal zone on land use manner,land use degree,land use structure,land use distribution and land use benefit.
