摘要: | 本研究係利用多期的SPOT衛星影像,透過光譜特性的變化來監測溪頭地區1994-2003間崩塌地變化的情形。首先利用11幅的SPOT影像區劃出不同時期間的崩塌地分佈位置,探討歷年崩塌地面積及分佈區位變化的情形,同時也透過不同時其崩塌地的套疊分析,探討崩塌頻度之情形。研究結果顯示,以1999年的921地震及2001年的桃芝颱風是造成溪頭地區崩塌地急遽增加的最主要因素。此外,透過相對NDVI的概念,分析特定地點崩塌地光譜變化的的情形,可以瞭解該崩塌地植生復原的變化情形,可做為未來崩塌地植生回復監測之依據。 The main purpose of this thesis was to investigate the change of the landslide by monitoring the spectral characteristics in Chitou area during 1994-2003. First of all, using 11 SPOT images drew the distribution of the landslide in different periods in Chitou area. Then we discussed the area of the landslide over the years and the condition of its location change. At the same time, we also discussed the frequency of the landslide by overlap analysis in different times. The result showed that the main cause of the dramatically increasing landslide in Chitou area was the 921 earthquake in 1999 and Tauchi Typhoon in 2001. In addition, we analyzed some extraordinary plots through the concept of relative NDVI to realize the restoration of the vegetation in landslide area in order to monitor the restoration in the future. |
