    摘要: 1996年政府推動全民造林,實施以來成果卓著,但在執行上仍有未盡完善之處,其中造林成果檢測工作由於造林地面積零星分散,實地進行查定不僅耗時、耗工且耗費金錢,也頗具專業性。因此,本研究以台北縣林口鄉為對象,探討以遙測技術取代或輔助實地造林成果檢測之可行性。研究結果顯示全色態航攝影像可以用以輔助判斷幼齡林之造林面積與存活率。對於林齡林長之林分,則可利用捷鳥衛星影像輔助林況之查核。林分之NDVI均值和林分胸高斷面積合計及林分鬱閉度有顯著正向關係,因此可以利用衛星影像計算各林分之NDVI平均值,或分類估測林分鬱閉度來評估造林成效。
    Since the National Forestation Champaign launched in 1996, the results have been very successful. However, there are also some shortcomings need to be improved. For example, the forestation tracts are so scattered that field checking of forestation success that requires professional knowledge is both time and effort consuming. This study took the Linkou Township of Taipei County as a study area to examine the applicability of remote sensing techniques in facilitating or replacing field assessment of forestation. Results suggest that for juvenile forestations, panchromatic aerial photo images can be used to estimate forestation size as well as to evaluate forestation success. For older forestations, satellite images can be used to facilitate the evaluation of stand conditions. The mean NDVI of a stand derived from the QuickBird satellite image was found to be positively correlated to the basal area and the crown closure of the stand significantly. Therefore, satellite images can be used to evaluate stand condition by calculating the mean NDVI of a stand, or by estimating the crown closure through image classification.
