dc.description.abstractIn this study, the data set came from Ta-Hsueh-Shan area,in the central part of Taiwan. We apply Geographic Information Systems technology analysis and inventory of forest site of attributes. By making use of ARC/INFO Geographic Information Systems and ERDAS Image Processing Systems ,along with QBASIC programming language of chan(1993), this study made an investigation of related problems. The summary of the obtained results is as follows: 1.Geographic Information System combined establish Primary Topographic Attributes (ex. Elevation,Slope,Aspect) and Compound Topographic Attributes (ex. Potential Solar Radiation, Moisture gradient class),it can overlay and analysis of different environment attributes. 2.The data set of Expert System well take Ta-Hsueh-Shan as an example, Utilize membership function of fuzzy sets established the associations of suitable site between physiological characteristics of tree species and environmental variables. The result showed that proper information to data base of Expert System. 3.Combined the Expert System and Geographic Information System in WINDOWS environment,We Using ARC/VIEW of Geographic System get all environment attributes and UTM coordinate. By analysis of Expert System the result show well, the observed and prediction value don''t significance diffent at 0.05% significance level. 4.The result of compare percent of survival with Expert System estimate value and prediction value. By way of sin-1 transformed and analysis of variance, it shows that the perdiction value of Expert System estimate result can represent observe percent of survival.en_US
dc.description.abstract本研究係以東勢林區管理處所轄之部份林班為例,探討專家系統與地理資 訊系統應用於森林生育地屬性之建立與應用分析,其係利用 ARC/INFO 地 理資訊系統與 ERDAS 影像處理系統軟體,配合陳(1993)所建立分析程式 及自行發展程式,以討論資訊建立過程之相關問題。其結果摘要如下:一 、地理資訊系統配合主要地形屬性(海拔高、坡度、坡向等)與複合地形屬 性(日輻射潛能、水份梯度等)之推導,及不同環境屬性間之套疊與分析, 整合之後可產生研究區之所有環境屬性。二、專家系統建立方面,以東勢 林管處歷年造林資料進行樹種隸屬度函數之推估,建立樹種生理特性及環 境屬性間之樹種適生程度,將所得結果輸入專家系統知識庫,所獲得結果 較能符合實際狀況。三、於 WINDOWS 環境下結合專家系統與地理資訊系 統,以 ARC/VIEW 地理資訊系統讀取研究區所有環境屬性及座標,可展示 其空間分佈狀況,該系統可選取圖層上任一點之屬性資料,將屬性值輸入 另一視窗之專家系統 後可產生該區域之樹種適生值作為尋求造林適地之 參考。四、將實際存活率與專家系統推論值進行比較,經由反正弦轉換後 ,再經變方分析(ANOVA),顯示專家系統推論值與各林班實際存活率之間 差異不顯著。zh_TW
