摘要:

以福建平潭综合实验区为研究区,收集2015年Landsat 8 OLI遥感影像数据、ASTER卫星GDEM V2产品,结合实地调查的数据,通过RS与GIS技术手段,对研究区地物类型与沿海防护林的空间分布进行信息提取;选取合适的效益评价指标,根据灰色关联分析计算权重,构建线性评价模型,同时运用该模型,对平潭各乡镇综合效益进行评价,将综合效益模型与NDVI拟合。结果表明,综合效益指数和NDVI指数的相关系数R为 0.80,两者之间的相关性较显著。该模型可为评估综合效益提供参考。

Abstract:

This study takes Pingtan Comprehensive Experimental Zone as the research area,collect Landsat 8 OLI remote sensing imagery data and production of ASTER satellite GDEM V2,combined with field survey data,through RS and GIS technology,extraction of the type of surface feature and coastal protection forest spatial distribution of information.Moreover,appropriate benefit evaluation index are selected and the evaluation model buildt to realize the evaluation on the comprehensive benefit of the spatial differentiation in coastal protective forest system. With the fitting of the comprehensive benefit index and the NDVI index,the results show that when R(correlation coefficient) is 0.804 0,the correlation between the two is significant. This model provides reference for comprehensive benefit evaluation.

Key words: comprehensive benefit, coast protection forest system, Pingtan Comprehensive Experimental Area
