Abstract

梯田信息准确和快速提取是区域水土保持动态监测和评价的核心技术之一,运用遥感技术进行地物信息提
取是一种有效手段。该研究以燕沟流域为研究区,采用高分辨率的SPOT5遥感影像数据,基于面向对象分类技术,
通过影像分割构建影像对象,在分析影像对象的光谱特征、纹理特征和空间特征的基础上,建立了梯田信息的遥感提
取规则,实现了梯田的自动提取。最后用手工勾绘结果对梯田的遥感提取结果进行精度评价,从田块边界的吻合度
评价位置精度,并通过比较该结果与人工目视解译结果进行面积精度评价。结果表明,基于面向对象分类的遥感方
法可以较好地从原始影像中提取复杂地貌区梯田的位置信息,面积提取正确率达到78.38%,该方法可为黄土高原地
区梯田信息遥感提取提供借鉴。

Other Abstract

Accurate and rapid extraction of terrace is one of the core technologies for the dynamic monitoring
and evaluation of soil and water conservation at a regional scale,and remote sensing technology provides an
effective and efficient means to extract land cover information.In this paper,image segementation and rule
based feature extraction were conducted to interpret the terrace information from the high spatial-resolution SPOT5
imageries in Yan′gou watershed on the Loess Plateau based on object-oriented classification method.Firstly,the
image objects were set through the image segmentation.Secondly,the rules for terrace information extraction from
remote sensing datasets were established via the analysis of spectral,texture and spatial feature of image objects.In
this case,the automatic extraction of terrace was achieved.Finally,the accuracy of extraction results was evaluated
through its comparison with visual interpretation results.The results showed that the position of terrace in complex
geomorphic regions could be successfully identified through the object-oriented classification method,and the
overall accuracy reached to 78.38%.The method developed in this paper is expected to provide a reference
for the interpretation of terrace information from remote sensing imageries across the Loess Plateau.
