中文摘要 | 浸水營闊葉樹自然保護區,屬林務局國有林班地,屏東林區管理處, 潮州事業區第16林班。全區面積432公頃,海拔在500公尺至1,688公尺。原始 闊葉林地佔242公頃(56%),造林面積佔190公頃(44%)。區內四面環山,中央為 凹地,有一力里溪,起源於姑子崙山。本區年平均溫度17.3℃,雨量集中在5月 -9月,年平均降雨量為3,680.5mm,為夏雨型氣候。植物清單中共採集到121科 387屬762種,包括59種稀有植物。例如:臺灣穗花杉列為國保級保護對象,假 桫 木最,南洋桫 木最,浸水營石爍等皆為本省固有種,僅出現於本區者。蕨類 商數高答11.3,顯示本區氣候之潮濕。評估22項環境因子與23個森林樣區,藉 由降趨對應分析及相關及顯著係測驗,找出主要的環境梯度軸及影響植群分佈的 主要因子。發現以海拔高,全天光空域,地形位置,pH值,K�楚A坡度及土壤 質地等有顯著相關,尤以海拔高及地形位置及土壤質地為影響植群分化與植物分 佈的主要因子。並藉由降趨對應分析所得出之分數重新加以排列,將森林植群加 以分類。原始森林植群依照特徵種及優勢共同命名,共分為三型及二亞型: A:長果木薑子─南仁鐵色林型B:山龍眼─假長葉楠林型B1柳葉科亞型B2台 灣黃杞亞型C:大武八角─鍵子爍林型. |
英文摘要 | The national Chinshuiying Hardwood Nature Reserve, located at the end of Centralmountains in Southern Taiwan, belongs to Compartment 16, ch'ao-chou working cicle, Pingtungforest district office, Taiwan Forest Bureau, Republic of China. The elevations range from 500Mto 1688M. The Reserve is about 432 ha including 242 ha (56) natural hardwood forest and 190ha (44) cultivated forest. It is surrounded by Ta-Shu-Lin Shan (1688M), Ku-tzu-lun Shan(1631M), Chinsbuiying (1450M) and one unknown Shan (1648M) so that the topography of theNature Reserve is valley. There is li-li Stream which original from Ku tzu-Lun Shan. In the plant inventory, there are 122 families, 387 genera, 762 species, among which 59species are rare. For example, Amentofaxus fonnosana had been protected by Law. BlecbaumA-asen, Cyatbea loberi sn@Litbocarpus silwsuiensis are endemic in Taiwan. The Climate wasStrongly humid because its pteridophyte-Quotient is 11.3 which the most high in Taiwan. The weather belongs to Summer rain climate because annual temperature is 17.3°C andannual precipitation is 3680.5mm concentrated from May to September. To evaluate environmental effect upon forest vegetation of this area, 22 environmevtal factorsare obserbed within 23 stand. The major gradient of communities variation is revealed byDetrended Correspondance Analysis (DCA) and Cormat program to test the significance ofenvironmental factors. Tabular rearrangement of primary data matrix was conducted on theordination Score of DCA. It is found that altitude, topography are the most signiFicant factors effecting plantdistribution and vegetation differentiation. Plant community can be classified by physiogonomy. The cultivated conifer and naturalhardwood forest are named by the characteristic and dominant species. It is concluded that thenatural hardwood vegetation would be classified as following scheme: A..Litsea aciltivena-Diypetes bieraoensis Type B.lfeffci'a formosana-Macbilus jopomca B1 Engelbaedtia roxburghiana Subtype Type B2 Litbocarpus dodonaeifolivs Subtype C.llliaum daibuense Cyclobalamopsis sessiUfolia Type. |
