Abstract

Taking Haikou coastal zone as the study area, we use comprehensive evaluation method to select a number of support factors and limiting factors to determine the indicators of ecological carrying capacity. Combined the data of social economic development of Haikou, using analytic hierarchy process model, the whole evaluation system will be divided into three assessment levels, including the target layer, criterion layer and index layer. With regard to the weights of each level, we use the information entropy method to figure out automatically. Taking into account the specificity of coastal areas, as well as miniature changes in statistics process, evaluation results are grouped into five categories: little load, normal load, full load, overload, and red load. The evaluation results show that the ecological coastal zone carrying capacity of Haikou from the year 2008 to 2012 raised slightly with an average annual growth rate of 7.88%, the minimum carrying capacity is about 0.17, and the maximum carrying capacity is about 0.23.In recent years, Haikou ecological carrying capacity is still under the normal load, and it will be further expanded if further control depends on scientific data and information.
