| 摘 要： | 在综合考虑气候、植被、地貌等凶素的基础上,提出一种基于多层次格网模型的最近邻指数-模糊聚类生态区域划分算法(Nearest Neighbor Index Fuzzy clustering,NNI-FIC).该算法采用"自下而上"的方式,首先,利用离散格网单元之间的严格相似性形成区划的核心分区;然后,通过最近邻指数统计分...

| Abstract: | The article presented a Nearest Neighbor Index Fuzzy Clustering(NNI-FC) algorithm for ecological regionalization based on multi-layer grid model with consideration of spatial distribution of geographical factors such as climate,vegetation and topography.It's a bottom-up regionalization approach and solved the problem of how to determine the ecological regionalization's type and its boundary by calculating the Nearest Neighbor Index(NNI) and the similarity between grids.Numeric and non-numeric features were ... |
