中文摘要	以福建省漳浦县沿海防护林为研究对象,通过遥感技术获取植被盖度、裸沙占地面积比、土壤可蚀性作为防护林防风固沙的效益评价指标,结合层次分析法构建防风固沙效益的评价指标体系,采用综合指数法制作1986年、2003年沿海防护林防风固沙效益评价图,实现了沿海防护林防风固沙效益的遥感监测.结果表明:植被盖度对土壤沙化程度影响较大,沿海防护林建设后起到了积极的防风固沙作用,漳浦县原有的严重沙化区域均向轻度转变,轻度的沙化区域面积从1986年的82.31 %增加到2003年的83.60 %.
英文摘要	Taking the wind-prevention and sand-fixation benefit of the coastal shelterbelt forest in Zhangpu county of Fujian province as the study object, the paper obtains the vegetation coverage, proportion of the area of bare soil and soil erodibility and makes them as the evaluated indicators for evaluation of the wind-prevention and sand-fixation benefit of the coastal shelterbelt forest according to the remote sensing technology. It constructs the indicators system of the wind-prevention and sand-fixation benefit, makes the evaluated maps of the benefit generated by the coastal shelterbelt forest in 1986 and 2003 with the help of comprehensive index method, and then it realizes the remote monitoring study on the wind-prevention and sand-fixation benefit of the coastal shelterbelt forest. The results showed that the vegetation coverage gave a significant impact on the soil deserted degree. The construction of the coastal shelterbelt had a positive function for wind-prevention and sand-fixation. In Zhangpu county, the mild desertification area had increased from 82.31 % to 83.60 % during 1986-2003, and the former severe desertification regions had been transforming to the mild.
