中文摘要 | 本研究應用自動照相設備收集野生動物之出現頻度資料,以地理資訊系統配合模糊集合理論,探討於多山及密林地區野生動物族群之空間分布型式。 從1995年10月到1996年5月之間,在位於屏東縣的「霧頭山自然保護區」內,使用自動照相設備34組,分別裝置於17個樣點,收集並計算臺灣山羌(Muntiacus reevesi micrurus)、藍腹鷳(Lopura swinhoii)、虎鶇(Turdus dauma)及深山竹雞(Arborophila crudiqularis)於各種點處之單位時間出現頻度(=被拍照片數╱有效的相機工作小時數),及其與海拔高、坡度、坡向及全天空光域等地形環境因子之隸屬度函數;再以隸屬度函數配合地理資訊系統,推估四種動物在保護區內可能之空間分布模式。結果顯示,四種動物在本保護區內均以海拔2,000公尺以下為主要分布範圍;在坡度方面,除了虎鶇無明顯之相關性外,其他三種動物均極少利用坡度超過45°之環境;四種動物對坡向都具有選擇性,以西南及南向坡的出現較為頻繁;在光量環境方面,全天空光域值超過50%的環境,四種動物皆極少出現。雖然所得結果正確之效度有待後續之評估檢驗,本研究顯示,以自動照相結合地理資訊系統,可應用在大面積的野生動物分布模式探討,並可於同一時間內收集及分析多種野生動物的資料,應有助於生態系統之經營與管理。 |
英文摘要 | The present study incorporated the occurrence data collected by auto-trigger cameras and a Geographic Information System (GIS), matched with the Fuzzy Set Theory, to predict the spatial distribution pattern of wildife in mountainous, dense forest habitat. From October 1995 to May 1996, 34 sets of auto-trigger cameras, which installed in 17 locations within the Wu-tou Mountain Natural Reserve, Pingtung, were used to collect the occurrence data in each location for the Formosan Reeves' muntjac (Muntiacus reevesi micrurus), Swinhoe's pheasant (Lopura swinhoii), White's ground thrush (Turdus dauma), and the Taiwan hill partridge (Arborophila rudiqularis). The membership functions between the frequency of occurrence (= number of pictures take per effective camera hour) and the elevation, slope, aspect and the whole light sky space was calculated for each species. These membership functions were then be used to generate the possible spatial distribution patterns for these species within the whole Natural Reserve. Results showed these 4 species distributed mainly below 2000 m, and, except for the White's ground thrush, they hardly used habitats with slope over 45°. All 4 species showed significant preference to sites which has a south-western or southern aspect, and they rarely used of environments with whole light sky space over 50%. Although the exact validity of these results require further evaluation, present study demonstrated the use of auto-trigger camera, incorporates with the GIS technique, may be used to generate the distribution pattern for wildlife in large geographic scale. It also can collect data for more than one species at the same time. The application of this method should be important in ecosystem management. |
