| 摘 要： | 选择江西省吉水县天然林森林资源与生态环境的有关指标,通过变异系数法筛选得到天然林区域类型划分的基础指标体系.采用主成分分析方法对多维森林资源与环境指标进行降维,获得主成分分析的第一至第三主分量,利用模糊聚类法对吉水县24个乡(镇)天然林进行区域类型划分,结果区划为4个区域.进一步对各区域天然林林种类型进行详细规划,为吉水县天然林的可持续经营与可持续利用提供理论依据.图1表3参8 |

| Abstract: | The basic index system of regionalization of types of natural forest was selected from correlative indexes of natural forest resource and environment in Jishui County of Jiangxi Province through variation coefficient process.Principal component analysis was adopted to reduce the dimensions of indexes of froest resource and environment to achieve from the first to the third principal component.Method of fuzzy clustering analysis was applied to divide regionalization of types of natural forest in 24 towns of Jishui into four regionalizations.Theoretic foundation was given to sutainable management and utilization of natural forest in Jishui by marking out different tree types of natural forest of every regionalization.[Ch,1 fig.3 tab.8 ref.] |
| Keywords: | silviculture natural forest division of types regionalization of types principal component analysis |
