摘要: 
達觀山自然保護區係以紅檜巨木群聞名,本研究主要進行植物社會及
生態衝擊調查。經由21個樣區調查共記錄植物種類376種,其中種子植
物304種,蕨類植物72種,生活型譜統計地上植物達75%,蕨類商數為5.98
,為溫帶冷涼重濕型氣候;植物群落依生育地及演替時期之差異可分為七
型,分別為:1.霧社木薑子-臺灣水絲梨、2.反刺櫧─小花鼠刺型、3.木
荷-卡氏櫧型、4.紅檜-西施花型、5.臺灣扁柏-臺灣杜鵑型、6.毽子櫟
-雲葉型及7.森氏櫟-白花八角型。透過極點分布序列與環境因子檢驗得
知:植群型之分化與海拔高、土壤pH值及太陽輻射相關。植物種間之相關
分析,有二群植物其群內樹種呈正相關,而群間則彼此呈負相關,顯示本
區為一不均質之植物社會。各樣區植物種類歧異度其新浦森指數在0.78
∼0.94之間,夏農指數在0.78∼1.32之間,各植群型植物種類歧異度其新
浦森指數在0.83∼0.95之間,夏農指數在0.97∼1.48,顯示本區為一較穩
定之植物社會。 巨木現況調查顯示:有二株巨木因自然因素已死亡,
一株因遊客引火幾乎滅亡,另有七株巨木遭受明顯之摩擦傷害;而巨木根
部之土壤裸露平均達38.5%。另區內紅檜巨木因參觀步道之開設,致生育
地受限而影響其更新;區外之臺灣扁柏巨木則因不受人為活動之干擾,故
其更新狀況良好。 針對環境衝擊問卷調查,共取得有效問卷1,243份
,分別為假日組953份,非假日組293份;主要探討遊客資料、遊憩經驗及
體驗、旅遊動機及目的、擁擠知覺、生態環境衝擊及管制措施等六項。分
析結果顯示:遊客資料中年齡層以20∼39歲為主,遊客的職業以學生最多
,其次為服務業及工人,另外遊客的教育程度以大專者為主,而性別則無
太大差異;另前來本區之旅遊動機主要為對自然喜好強烈及對巨木好奇;
而旅遊目的以觀賞巨木為主;有17.25%之遊客認為環境遭嚴重破壞,
有20.16%之遊客認為巨木遭嚴重干擾。遊憩體驗之滿意度達83.27%,再度
重遊意願為82.95%;擁擠指標假日組為0.13,非假日組為0.03;有68.09%
之遊客認同本區應當實施人數管制。
The investigation on plant community and analysis of
visitorquestionnaire about ecological impact were performed in
the study forTakuanshan natural reserve. There were 376 species
found at 21 sampleplots, including 304 species of spermatophyta
and 72 species ofpteridophytes. The phanerophyte is 75.01%, the
pteridophyte-quotient is5.98, and the area is classified as
temperate heavy moist type of climate,as shown in the life form
analysis. The habitat and succession in the plantcommunity were
classifided into seven types by matrix cluster analysis(MCA)
presented as follows: (1). \AS;Litsea elongata\AS; var.\AS;
mushaensis\AS;-\AS; Sycopsis sinensis\AS; Type, (2).\AS;
Castanopsiseyrei\AS;-\AS;Itea parviflora\AS; Type, (3).\AS;
Schima superba\AS; var.\AS;superba\AS;-\AS;Castanopsis
carlesii\AS; Type, (4).\AS;Chamaecyparisformosensis\AS;-\AS;
Pasania brevicaudata\AS; Type, (5).\AS;Chamaecyparisobtusa\AS;
var. \AS;formosana\AS;-\AS;Rhododendron formosanum\AS;
Type,(6).\AS;Cyclobalanopsis sessiliforia\AS;-\AS;Trochodendron
aralioides\AS;Type\, and (7).\AS;Cyclobalanopsis morii\AS;-\AS;
Illicium tashiroi\AS;Type. As shown in the results of
correlation test between PolarOrdination method and environmemt
factors, altitude, pH value of soil,slope and solar radiation
are concerned with vegetation differentiation.Itshows that the
vegetations within the study area can be divided into twogroups
by interspecific association. As shown in the population
structureand species diversity analysis that vegetation are
situated in the morestable stage. Visitor interviews were
conducted during October 1995 and January 1996.A total of 1,243
questionnaires were collected. Six main subjects weresurveyed,
including : the concept of understanding the environmental
impactof Takuanshan natural reserve, basic visitor information,
recreationalexperience of tourists, motivation and aim of
touring, and consciousness ofcrowding. The results showed that
the age group of tourists were concentrated inthe 20-39
(65.72%), and a large proportion(82.14%) of tourists had
aneducation level above high school, and more than half of them
had a collegeeducation and above. The largest occupational group
was students(28.64%),followed by business of service (19.55%)
and labor(15.77%). But there wasno obvious difference in the
sex. The decided factor of touring included tobeing close to the
nature(91.01%), curiosity to the giant trees(79.89%), totake
green shower(77.47%) and being invited by friends(70.31%).
Themotivations for tourists visiting the Takuanshan natural
reserve were toadmire the giant tree(90.91%), and to take green
shower(85.28%). 83.27% ofthe tourists were satisfied with their
recreation experience and 82.95% ofthem would like to revisit
the Takuanshan Reserve in the future. And 68.09%of tourists
consent to a purposed of the recreational capacity control.
The data obtained in this survey can serve as a good reference
for themanagement of Takuanshan Reserve in the future.
