摘要
运用年际集中指数、最邻近点系数、地理集中指数、基尼系数等方法,对我国野生动物园的时空分布进行了量化分析.结果发现:我国1993—2010年间开业的野生动物园的年际集中指数为0.039,年际差异性小,开园时间较为分散;最邻近点指数接近于1(0.991),属随机型分布类型;各省级行政区间分布的地理集中指数为22,空间上较为分散;在八大区域间分布的基尼系数为0.973,分布较为集中;在八大区域间的空间密度差异较大,尤以北部沿海、东部沿海、南部沿海和长江中游地区密度较高.
By using the annual concentration index,the nearest point coefficient,geographic concentration index and Gini coefficient,this paper quantitatively analyzed the spatial and temporal distribution of wildlife parks＇ feature in China.And the authors get the following conclusions： between 1993 and 2010,the annual concentration index of wildlife parks in China is 0.039,small differences in annual,the time parks opened is dispersed.The nearest point coefficient of wildlife parks is close to one（0.991）,so the distribution type of China＇s wildlife parks is stochastic type.The geographic concentration index of wildlife parks distributed in the provincial administrative is 22,space is more dispersed.Within the eight economic regions,the distribution of wildlife parks is more concentrated,which has a high Gini coefficient（0.973）.The spatial density in the eight regions is quite different;especially there is a higher density in north coast,east coast,south coast and the Yangtze River middle reaches.
