摘　　要：研究我国国家级自然保护区数量特征对加强保护区建设和管理具有重要意义。本文通过资料收集,采用方差分析、多元比较、相关分析等数理统计方法,分析了我国国家级自然保护区数量和面积的分布格局、各类型保护区各功能区划面积比例及功能区面积与物种的关系等数量特征。结果表明,我国国家级自然保护区数量上以森林生态系统类型最多;面积上为荒漠生态系统类型最大;面积分布格局呈现从西向东及从北向南逐渐减少的趋势。方差分析表明不同类型国家级自然保护区3个功能区面积所占其总面积的比例之间差异不显著;相关分析表明在以物种为保护对象的保护区中,其总面积、各功能区面积与物种数量、动植物种类的相关性显著。该研究相关结果为我国自然保护区的建设与管理提供一定的参考依据。Researches on national nature reserves of China are of great importance on the construction and management of these reserves Based on the collected dataset, the quantitative characteristics of the reserves and the relationship between function areas and species were analyzed by variance analysis, multivariate comparison and correlation analysis. Results showed that the maximum numbers of all kinds of the reserves were forest ecosystem. For the area, the maximum areas were desert ecosystem. The distribution pattern of the reserve area exhibited a declining trend from west to east and from north to south in China. The variance analysis showed that there are no differences among the proportions of areas of three function area to the total area in each type of the reserves. In the species-protected reserves, there was significant correlation between the total area of the reserves, the area of each function area and the number of species, plant or animal species, respectively. In summary, results of this study provide some guides for the construction and management of the nature reserves in China.
