运用空间统计分析与GIS技术的综合集成方法,针对中国31个省(市、自治区)第二次至第八次(1977~2013)全国森林资源清查数据,研究各省区森林资源增长率空间关联性规律及其演变过程。研究结果表明,全国森林资源增长率空间聚集表现为前期趋同趋势减弱阶段,后期省际间资源增长率趋同趋势增强,达到2013年Moran’sI指数达到最高值0.4155;资源增长率局部空间自相关则表现为森林资源增长高值省区主要集中于京津冀和“长三角”东部沿海地区,而森林资源增长缓慢的落后区域则聚集在广大的西部地区。
Using spatial statistical analysis and geography information system (GIS), forest resources inventory data from 1977 to 2013 were studied in 31 provinces. The spatial relationship rule and developing process of all the forest resources increments rate were found. Empirical result follows: in China, spatial clustering of the forest resources in- crement rate were weakening in earlier stage, but the spatial relationship term trend enhanced, and global Moran' s I achieved 0.4155 in 2013. Local spatial autocorrelation showed the high-value of forest increment rate mainly fo- cused on Beijing-Tianjing-Hebei region and Yangtze river delta in eastern coastal of China, but the low-value of forest increment rate focused on the extensive of the western China.
