摘要
依据森林生态学、地学规律和遥感图像解译原理,在处理过的卫星遥感照片上判读勾绘类型小班,采用数量化理论Ⅱ和排序法确定立地类型,经数量化方法Ⅰ进行精分类,将连云港云台山区森林立地划分为13个立地类型,样地的平均判对率为94.59%。同时利用模糊数学综合审评法对分类结果进行立地质量评定,分别立地类型计算出模糊综合评判值,分类精度为63.39%。经实地调查对立地分类与评价的结果进行验证,其精度满足生产应用需要。
With the principles of forest ecology and geology as well as remote sensing science, the forest sites in Yuntaishan mountain area,Jiangsu province,were divided into 13 site types through the method of quantitative theory Ⅱ. The mean estimated rate was 94.95%. Furthermore, the site quality of each type was evaluated also With fuzzy theory. With the very- lying of field investigation data the results of classification and evaluation were suitable. Classification precision was about 63.39%. And also the evaluation value of each site type was calculated. The classification and evaluation technologies on forest sites with remote sensing technology were also given in the paper.
