Classification based regionalization is an effective way to analyze geographical national conditions and a basis for studying the regional differences in the classification characteristics, combinations, change, and spatial differentiation of geographical national conditions. The index system of the classification-based regionalization of geographical national conditions is determined through the analysis of the basic statistical data of the geographical national conditions survey. Using multidimensional scaling and cluster analysis, the classification-based regionalization model of geographical national conditions was established. The classification-based regionalization experiment was carried out using the geographical national conditions survey data of Henan Province. The number of regions of geographical national conditions was initially intuitively determined through multidimensional scaling on geographic national conditions data of Henan Province. On this basis, the classification-based regionalization was achieved by K-means clustering. The type of regions is defined and explained according to the cluster centers and the characteristics of index data in each cluster. Finally, the clustering result is spatialized. The experimental results show that the geographical national conditions in Henan province can be divided into four regions: extreme value region, low value region, median value region and high value region. The spatial agglomeration effect of regions of geographical national conditions in Henan Province is significant, and It is mutual tolerance and penetration between each classification-based regionalization and constructed of four southwest to northeast strip. In the overall planning of regional development and realizing regional coordinated and sustainable development, we can make feasible regional balanced development policies according to the geographical national conditions of each region.
