摘　　要：自然保护区建立对于生物多样性及生态保护具有重要意义。收集了截至2012年底我国自然保护区有关资料,运用R-Q型分析、基尼系数等方法,探讨我国自然保护区数量与面积均衡性关系特征。结果表明:1)古生物遗迹类型自然保护区从数量和面积上都处于相对弱势地位,分别占保护区总数和总面积的1.20%,0.37%;2)不同类型自然保护区与分布地区间存在一定的关联性,区域之间分布不平衡;3)各省自然保护面积和数量基尼系数与保护区级别呈现一定趋势性,基尼系数接近0.5水平,甚至超出0.7。由于资源禀赋,经济条件等因素不同,不同地区自然保护区面积和空间网络体系存在差异,9大类型自然保护区地区分布差异明显,自然保护区数量(面积)与国土面积,数量与保护区面积关系均呈现集中分布特征。It is of great significance to set up nature reserves for biodiversity and ecological protection. We collected the relevant information of nature reserves by the end of 2012,using correspondence analysis and Gini coefficient to discuss the balance relationship between number and area of nature reserves. The results show that：1） The type of paleontological relics nature reserves in our country were in a relatively weak position from numbers and areas,accounted for the total number of 1. 20% and the total area of 0. 37% respectively. 2） The distribution of different types of nature reserves between regions appeared certain correlation but imbalance between regions. 3） The Gini coefficient appeared to be a certain trend between levels and areas or numbers for different nature reserves in our country,and the Gini coefficient was close to 0. 5 levels,even higher than 0. 7. Because of the factors of resources endowment and economic conditions,differences existed in nature reserve area and space network system between regions. There was a clear different distribution between 9 types of nature reserve for regions,the nature reserve quantity（ area） and national territorial area,reserve number and area showed an imbalance characteristics,both presented concentration distribution characteristics.
