| Summary: | 碩士 === 國立中興大學 === 森林學系 === 81 === 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.
