- 摘要:
- 基于“3S”技术,利用泰和至井冈山高速公路建设前(2001年)、建设中(2004年)及建设后(2005年)的3个时相的Landsat-TM5遥感数据对公路建设影响区的施工场地、取弃土场地等有人为活动干扰的敏感区域进行植被覆盖动态变化分析,结合GPS野外定位等现场调查实际情况进行比对,结果表明:在公路沿线的各敏感区域内,公路建设前的原始植被覆盖率要整体上高于建设中及建设后的;少数施工场地在公路竣工采取地表恢复后的植被覆盖度仍较低,植被有待于进一步采取措施恢复;基于遥感技术分析的公路建设后各敏感区域植被恢复情况与野外调查的实际状况较吻合,以“3S”为技术手段的植被盖度动态变化分析方法可以用于公路建设影响区的环境保护验收中.
- Abstract:
- Based on ‘3S’ technique,applying three different time RS data(time before the construction-2001,among construction-2004 and after construction-2005) of Landsat-TM5 analyzed the vegetation fraction changes for the sensitive area of the speedway from Taihe to Jinggangshan.After the comparison with the fieldwork investigation,the result indicated:the vegetation fraction of the time before highway construction was larger than the one of time among construction and after construction in the sensitive range along the highway.Vegetation fraction of few sensitive area was relatively low and it should adopt more measures to renew it.The situation of the vegetation monitored by the remote sensing was correspond to the fieldwork investigation result,so the vegetation fraction dynamic change analysis method based on the ‘3S’ can be used in the environmental protection for check and accept project.
