摘　　要：物种多样性是指一个地区内物种的多样性化,主要是从分类学、系统学和生物地理学角度对一定地区内物种的多样性的现状、威胁状况、物种多样性的形成、演化及维持机制以及物种濒危灭绝的速率及原因、生物区系的特有性、如何对物种进行有效的保护与持续利用等进行分析研究。研究表明,当一个国家的森林面积超过30%,且森林在分布上比较均匀,森林内的物种比较丰富,并保持较高的质量,就能维护良好的生态系统,而物种多样性的高低是评价生态系统质量的一个重要指标。本文以昆嵛山为样本,在水平指标上从物种丰富度和植被覆盖度两个角度对物种多样性进行分析研究,将两者综合之后得出昆嵛山物种水平指标分级图,对今后昆嵛山自然保护区物种调查和日常管理具有指导意义。Species diversity was the diversity of species within a region, mainly from the perspectives of taxonomy, systematics and biogeography, the status of species diversity within a certain region, threatening conditions, the formation of species diversity, evolution and maintain mechanisms and rate of extinction of endangered species and the reasons, biota endemism, how to effectively conserve and sustainable use species, etc. were analyzed and researched. Research results showed that when a country＆#39;s forest area was more than 30%, and more evenly distributed in the forest, relatively abundant species within the forest, and maintained a high quality, will be able to maintain a good ecological system, and the level of species diversity is an important indicator of evaluating the ecosystem quality. In this paper, taking Kunyushan as a sample, the species diversity was analyzed and researched from the two perspectives of species richness and vegetation cover at horizontal indicator, integrated two grading chart of species level indicator at Kunyushan area was got, and it has guiding significance for future species surveys and daily management in Kunyushan nature reserve.
