遙測影像應用於桃園地區埤塘之變遷分析

Application of remote sensing images to irrigation pond change analysis in Taoyuan

指導教授 : 鄭克聲

摘要


農業式微,工商興起,埤塘地景是人類與環境共生下的歷史地景,具豐富的人文價值與生態價值,逐漸消逝在桃園台地。埤塘的定義為灌溉水池、魚池、蓄水池,且面積在0.3公頃以上者。本研究目的利用遙測影像偵測埤塘地景變遷。衛星遙測具宏觀與周期資訊的特性,配合影像的分類可偵測地表使用情況,以獲取變遷資訊。研究中使用1904年台灣堡圖數位化地籍資料、1969年桃園地區CORONA衛星影像與2004年及2014年SPOT5衛星影像。SPOT5衛星影像具有多光譜資訊,其中遠紅外光及短波紅外線能有效的辨識埤塘;而CORONA衛星影像為全譜態,需藉由紋理分析增加分類的依據,以增進分類的正確率。單以紋理特徵作為分類依據時,能夠依照地物表面紋理將其分辨為各分類類別,並進行紋理分析。計算紋理特徵時,在各參數中,影響最大的為選擇移動網格尺寸;而在適用於遙測的六種紋理統計指標中,其分類成果差異不大。最後,配合推理判釋之技巧,可清除多選出來被誤判為埤塘的農田像元。 由時政回顧與變遷形態圖發現,1904年至1969年變遷原因為日治時期水利組織的建立使私人埤塘整併、桃園大圳竣工,並且因應台北快速發展下大型建設興起;1969年至2004年石門水庫的建立與石門大圳的開通,使埤塘的功能式微,工業帶動都市發展而產生的變遷,都市由面狀逐漸擴張為帶狀,使都市邊緣的埤塘快速消失;2004年至2014年桃園工業與發展至一個段落,台灣人民開始注重環境品質與台灣農業的永續,因此開始積極的保護埤塘,除了政府通過桃園市埤塘水圳保存及獎勵新生利用自治條例,許多社會組織也投身埤塘保護的事業中。

The industry and commerce rose after the agriculture descended. The landscape of ponds which contains many historical value, humanistic value and ecological value is now gradually disappearing at Taoyuan tableland. This research applies remote sensing images to observe the changing of the ponds. We can obtain the information from remote sensing images of objects indirectly and learn the usage of land by classifying the images. In this research, we apply Taiwan Bao-tu of Taoyuan in 1904, Corona satellite image of Taoyuan in 1969 and SPOT5 satellite image of Taoyuan in 2004 and 2014. The multispectral of near infrared and Short-Wave Infrared from SPOT5 satellite can classify the ponds effectively. However, the images of Corona satellite are panchromatic. We can rise the accuracy of the classification by texture analysis. In the analysis of textural features, the most influential part is to choose the moving window size. Furthermore, there is unapparent difference between six methods of texture statistics that can use to remote sensing. Also, we can eliminate the clutter of farmland pixel form ponds pixel by the skill of inference. As a result, from 1904 to 1969, the reason of transition is the development of water facilities that merging the ponds, the construction of the Tao-Yuan Irrigation Association and the vast construction for developing Taipei through the history and the change of patterns. Then from 1969 to 2004, because of the build of Shihmen Reservoir and Shihmen Irrigation Association, the function of the ponds gradually declined. Industrial development made the ponds near urban disappeared. The last part from 2004 to 2014, the industrial development in Taoyuan reached to the ceiling and people began to aware the importance of our environment and the sustainable development of the agriculture in Taiwan. For this cause, people and many social organizations started to protect the ponds. The government also legislates regulation to protect the ponds.
