Abstract: With the urgent problems of increasing population pressure, land resource shortage and ecological destruction in the coastal zone of Hainan island are necessary to quantify the conditions of land use and ecological carrying capacity efficiently. Based on the land use classification and coastline dataset in 1990, 2000, 2009 and 2015, the intensity of land development and utilization and ecological carrying capacity in the coastal zone of Hainan island are evaluated and analyzed. The results show that: ① Arable land and woodland are the main land types in the coastal zone of Hainan island. ② Overall, in the past 25 years, the land use intensity in the coastal zone of Hainan island was high and increased annually. From 2000 to 2009, the land use intensity had the highest rate, reaching 2.03%. Haikou city and Chengmai county had the highest average land use intensity during the study period, which was 300.5 and 286.1 respectively. ③ Over the past 25 years, the coastal ecological situation of Hainan island has deteriorated gradually, and the actual ecological carrying capacity of 57% of the coastal cities and counties has increased more than double.
