中文摘要 | 臺灣目前正在生態系經營理念下,整合地面調查、遙測、衛星定位系統、地理資 訊系統與永久樣區設立等技術於森林資源調查與監測。本研究針對臺灣全島的調查說明外, 更以中興大學的惠蓀實驗林場、新化實驗林場以及東北角風景特定區為科技發展的研究地點 ,進行探討。惠蓀實驗林場,面積範圍7500ha,位於臺灣中部南投縣;新化實驗林場,面積 範圍550ha,係位於臺灣南部臺南縣;而東北角風景特定區,則位於臺灣東北部,面積範圍 9450ha。GIS的士地利用型圖層係由航空測量之遙測資料判釋、數化而成,林分結構與蓄積 的資料,則由永久樣區調查而得。惠蓀林場、東北角風景特定區的地景資訊與土地利用變 遷,有進行趨勢分析。 以不同尺度層級的永久樣區所獲得之地理空間有關的調查資料,進行不同尺度GIS的森林屬 性更新。這些不同尺度層級包括:地景、林分樣區與單株林木。永久樣區位置圖及其內之 林木位置圖,係由羅盤儀、雷射測量儀和衛星定位系統之儀器工具,完成之地理空間資料 可用來檢視不同樹種、林型與其生育地的關係。科學技術的研發,目前仍繼續進行中,有 關長期間、大尺度的資原調查與環境的監測,亦繼續研發中。 |
英文摘要 | Ground surveys, remote sensing (RS), global position systems (GPS). geographic information system (GIS), and permanent sampling plots (PSP) were used to inventory and monitor forests in order to develop of an Ecosystem Management Plan for the island of Taiwan. While the entire island had been surveyed, this study was conducted at the Hui-Sua and Hsin-Hua Experimental Station of Chung-Hsing University and Northeast Coast National Scenic Area. The Hui-Sun Experimental Station, 7,500 ha, is located in the middle part of Taiwan island, the Hsin-Hua Forest Experimental Station, 550 ha, is in the southern part of the island, and is located the Northeast Coast National Scenic Area, 9450 ha in the northern part. GIS land-use maps derived from the aerial photographs of RS were used to select and survey PSP for information of forest stand structure and growing stock. This information on the landscape patterns and changes of land-use was used in the Hui-Sun Experiment Forest Station to detect changes in trends. The geo-referenced surveyed data from the PSP were used to update forest attributes in GIS at different scales: landscape, forest stand, and tree. A tree location map was developed using compass, laser surveyor and GPS techniques within each PSP. The geo-referenced database allowed for the examination of the relationship between different species and their habitat. The technigves and problems of resource surveys and environmental monitoring at large scales over a long term are all on-going projects. |
