摘　　要：利用海口市2008年社会经济数据,采用生态环境效应评价模型,对研究区构建区域土地利用变化生态环境影响效应评价指标体系,通过层次分析法得到各个指标的权重,进而得到海口市滨海旅游区2008年生态环境效应评价指数,并在GIS中通过空间叠加分析得到研究区不同土地利用格局的环境效应状态评价。结果表明:2008年海口市滨海旅游区,生态环境综合效应指数为0.582,结合生态环境质量评判标准,得出该区域生态环境处于一般状态,生态系统服务功能已有退化。研究区不同土地利用格局表现出不同状态,主要表现在建设用地生态环境恶劣,未利用地生态环境较差,耕地生态环境状态一般,水域生态系统处于良好状态,有林地和湿地的生态环境处于理想状态。Using socio-economic data of Haikou City in 2008 and eco-environment assessment model,built index system of ecological environmental impact evaluation on regional land use change in study areas,obtained the weights of each index through Analytic Hierarchy Process,then got eco-environmental effects assessment indexes of Haikou coastal tourism zone in 2008,through space overlay analysis in GIS,got environmental effects state valuation of different land use patterns in study areas.The results show that the combined eco-environmental effects index of Haikou coastal tourism zone in 2008 was 0.582,with environmental quality criteria,it is inferred that the regional ecological environment is in general state,the ecosystem service function has been degraded.Different land use patterns in study areas show a different state,mainly reflect in that the eco-environment of construction land is harsh,the eco-environment of unused land is bad,the eco-environment of farmland is in a general state,the water ecosystem is in good condition and the ecological environment of woodland and wetland is ideal.
