遥感影像判读技术在林地变更调查中的应用探讨

Application of Remote Sensing Image Interpretation Technology in Survey of Forest Land Change

指出了遥感技术在森林资源调查中应用广泛,研究林地变更调查中的遥感影像判读技术,能够有效提高变更调查结果的精度,确保森林资源管理“一张图”的真实性和准确性。结合2017年度广西都安县林地变更调查项目,利用高分辨率遥感影像,参考林业经营管理档案,对变化图斑进行修正和判读,并对判读结果进行了分析。提出了影响遥感影像判读的主要影响因素,为森林资源调查中的影像判读提供参考。

Remote Sensing technology is widely used in forest resources surveys.The Remote Sensing image interpretation technology in forest land change surveys can effectively improve the accuracy of survey results and ensure the authenticity and accuracy of"one map"of forest resource management.Based on the 2017 forest land change survey project in Du'an County,Guangxi Province,this paper used high-resolution remote sensing images,referring to forestry management files to correct and interpret the changes and analyze the interpretation results.This paper studies the main influencing factors of remote sensing image interpretation,which provides reference for image interpretation in forest resources surveys.
