摘要
[目的]查明豫西山区部分区域内崩塌、滑坡等地质灾害的空间分布特征,为地质灾害监测与治理提供科学依据.[方法]主要利用高分七号卫星影像数据,通过构建遥感解译标志、室内初步解译、野外核查验证、内外业综合解译、编制解译成果图件等步骤开展遥感解译工作.此外,还对比分析了多类型多时相的遥感影像,并结合研究区的地形地貌等地质资料,进一步提高了地质灾害的可解译性.[结果]在此次地质灾害遥感解译中,实际正确识别了15处滑坡、6处崩塌,解译正确率达91.3%.遥感解译的精度和效率较高,取得了较好的成果.[结论]本研究提出的利用高分七号遥感卫星数据开展地质灾害遥感解译思路及方法,在该地区所进行的地质灾害遥感解译工作中表现出显著优势,具有较强的实用性和可行性,能够为其他地质灾害遥感解译工作提供有力的参考和指导.
Abstract
[Purposes]The aim of this paper is to identify the spatial distribution patterns of geological disas-ters such as collapse and landslide in some areas of the western Henan mountainous areas,and to provide a scientific basis for disaster monitoring and management.[Methods]The primary data source is GF-7,and the remote sensing interpretation process includes the steps of the construction of remote sensing interpreta-tion signs,preliminary indoor interpretation,field investigation verification,comprehensive indoor as well as outdoor interpretation,and the compliation and interpretation of results maps.In addition,this paper com-pares multi-type and multi-temporal remote sensing images and combines the geological data from the study area to further improve the interpretability of geological disasters.[Findings]The results show that 15 land-slides and 6 collapses were actually correctly identified in this survey,with a correct interpretation rate of 91.3%.The remote sensing interpretation has achieved rather high accuracy and efficiency,and obtained bet-ter results.[Conclusions]The idea and method proposed in this paper for geological disasters remote sensing interpretation using GF-7 satellite data have demonstrated significant advantages in this remote sensing inter-pretation of geological disasters carried out in the region,with strong practicality and feasibility,which can pro-vide powerful reference and guidance for other geological disasters remote sensing interpretation.
