摘要:大巴山脉地处北半球亚热带的核心区域,该区生物区系起源古老、物种资源丰富、生态系统完整,保存有较多珍稀濒危、特有及古老生物类群,是中国17个生物多样性保护关键区域之一。为更好的保持本区域生态系统的稳定,本文对大巴山区生物多样性保护现状进行了分析讨论,旨在为更好的保护大巴山区生物多样性提出相应的保护对策。并在护林联防原有宗旨基础上,赋予“川陕鄂渝巴山地区护林联防委员会”更具时代意义的内涵,将“护林防火”提升为“生物多样性保护”,将该组织更名为“大巴山生物多样性保护联盟”。

Abstract: The mountain is located in the northern region of the northern subtropical subtropical core area, the origin of the biota is ancient, rich in species rich, complete ecosystem, preserved more rare and endangered, unique and ancient biological groups, is China's 17 key areas of biodiversity conservation one. In order to maintain the stability of the ecosystem in the region, this paper analyzes and discusses the current situation of biodiversity conservation in Daba Mountain area, and aims to provide corresponding protection measures for better protection of biodiversity in Daba Mountain area. And in the protection of the original purpose of the forest defense, given the “Sichuan-Shaanxi-Hubei-Chongqing Bashan area forest protection committee” more meaningful connotation, the “forest fire” to “biological diversity protection”, the organization changed its name to “big Bashan Biodiversity Conservation Alliance ”.

生物多樣性是指在一定时间、空间内所有生物物种及其遗传变异和生态系统的复杂性总称,主要包括遗传多样性、物种多样性、生态系统多样性三个层次。近年来随着人类社会的不断发展,人们开始注意到自然资源的合理利用和生态环境的保护,生物多样性的研究和保护也随之成为世界各国普遍重视的一个焦点问题。

大巴山脉作为中国17个生物多样性保护关键区之一,已成为中国乃至世界生物多样性保护的焦点[1]。大巴山脉地处北半球亚热带的核心区域,共涉及28个县级行政区,包括12个国家级自然保护区。该区生物区系起源古老、物种资源丰富、生态系统完整,主要保护对象包括巴山松林、包石栎林、多脉青冈-水青冈林等生态系统以及崖柏、川金丝猴、红腹锦鸡、大鲵等重要物种及其栖息地。……
