臺灣博碩士論文加值系統

本研究以中興大學惠蓀實驗林場木荷保護區為範圍,應用地理資訊系統(
Geographic Information System,GIS), 建立以稀有母樹林植物為保護對
象之木荷生態資料庫; 其資料庫結構係基於環境層級系統中之位置因子(
Physiographic factor)及配合GIS中之數位地型(DTM)資料所推導之合成
環境指數為理念, 以GIS軟體-GENAMAP 結合 立木之屬性資料與位向空間
資料以建立木荷生態資訊系統( Ecological Information System,
EIS), 本系統可供單株林木及其生育地性態值快速查詢之用。研究結果顯
示 : 1.海拔高最能影響木荷之天然分布. 2.木荷最適生態區域為海拔
高1000-1050公尺、坡度0-20%、坡向為270-315度屬於西北向、水分 梯度
指數為10、全天光空域40-70%, 本研究, 可供自然資源及生態資料庫建立
之參考。

In the paper,the data of nature reserve of Schima superba in
the Huisun Experimental Forest Station were used to study. GIS
were used to set up the site data base for delicate rare
plants, Schima superba. The site data base built was based on
physi- ographic factors of environment hierarchical system and
the syn- thetic environment index derived from the digital
terrain model (DTM). GENAMAP are used to integrate the
attributes of standing tree with topographical spatial data.
The site data base is called Ecological Information System
(EIS). EIS is easy to query the attribute and spatial data of
individual tree. The results were showed as following:1.
Elevation is the key factor in environmental mechanism of
schima. 2. The ecological optimum are elevation 1000-1050m ,
slope 0-20%, aspect 270-315 degree (westnorth ),moisture
gradient class index 10, whole light sky space (WLS) 40-70%;
The study could be regarded as a reference on establishing the
ecological data base of natural resorce.
