Forestry division method at county level based on GIS with integrated modeling

Abstract

Forestry division has been discussed rarely since 1995 in China. The growing interest in forestry provides an opportunity to improve the research tools and approaches that can help achieve a broader understanding of forestry division. Based on research in Yong’an, Fujian Province of China, a framework that may be useful in correlative forestry division study was proposed: 1) the factor-system for Yong’an forestry division was established; 2) the factors were extracted with spatial analysis; 3) the forestry division method of integrated modeling at county level based on GIS was processed. The method was taken through principal components analysis, building the comprehensive model, discriminate analysis, seeking the ideal number of divisions and eliminating the scrappy polygons. The outcome showed that the method based on GIS with comprehensive modeling could reflect the present situation of forestry development. The relative dominant subdivisions were distinguished reasonably, and a specific direction in forestry development is presented. According to the statistics of the subdivisions’ state, the relative dominant subdivisions were clearly demonstrated.
