1、第33卷第11期中南林業(yè)科技大學學報Vol.33No.112013年11月JournalofCentralSouthUniversityofForestry&TechnologyNov.2013石門臺自然保護區(qū)不同森林群落類型結(jié)構(gòu)組成及物種多樣性12解丹丹，蘇志堯（1.許昌學院城市與環(huán)境學院，河南許昌461000;2.華南農(nóng)業(yè)大學林學院,廣東廣州510642）摘要：基于3個標準樣地（100m×100m）植被的全面調(diào)查，研究了石門臺自然保護區(qū)針闊葉混交林、常綠闊葉林和山頂矮林3類典型森林群落冠層樹種的結(jié)構(gòu)組成和物種多樣性特征。結(jié)果表明：針闊葉混交林、常綠闊葉林和山頂矮林
2、冠層樹種組成分別為31科41屬48種、23科39屬49種和38科58屬75種；科、屬、種組成復(fù)雜，優(yōu)勢科和優(yōu)勢種明顯，3類群落共有的科和種分別為茶科Theaceae和木荷Schimasuperba；常綠闊葉林結(jié)構(gòu)穩(wěn)定，除密度和蓋度外，胸徑、樹高和冠幅均高于針闊混交林和山頂矮林，山頂矮林結(jié)構(gòu)穩(wěn)定性次之，針闊混交林結(jié)構(gòu)極不穩(wěn)定；除物種豐富度外，山頂矮林、針闊混交林的物種Shannon-Wiener指數(shù)、Simpson指數(shù)、物種均勻度均顯著高于常綠闊葉林。本研究結(jié)果為生物多樣性保護、退化生態(tài)系統(tǒng)的恢復(fù)重建提供了科學依據(jù)。關(guān)鍵詞：群落結(jié)構(gòu)；物種多樣性；物種組成；石門臺自然保護
