摘要：提出了基于G IS的县级林业区划方法框架;建立了永安市林业区划因素体系,并运用空间分析方法对各因子进行了提取;探讨了基于G IS建模技术的县级林业区划方法。通过主成分分析、建立综合模型、判别分析、确定合理分区个数和清除细小多边形等过程,最终得到的区划结果能够将各相对优势区域合理分开,分区林业生产状况统计数据能较清晰地反映各分区的资源状况和相对优势,林业建设发展方向较为明确。
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 broad understanding of forestry division. Based on the research in Yong＇an, Fujian Province of China, a framework that may be useful in correlative forestry division study was put forward ： （ 1 ） The factor-system of Yong＇an forestry division was established ; （2） The factors were extracted with the 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 integrated model, Discriminate Analysis, seeking the ideal number of divisions and eliminating the scrappy polygons. The outcome showed that the method based on GIS with integrated modeling can reflect the present situation of the forestry development. The relative dominant subdivisions were distinguished reasonably, and a specific direction in forestry development was given. According to the statistics of the subdivisions＇ state, the relative dominant subdivisions were showed obviously.
