研究对象只限于散生于江西省山下及村落的30851株古树,不涉及自然保护区、森林公园中的古树。根据古树生长特征,分析其时间分布(古树级及树龄)、空间分布(设区市分布、县域分布),借助于动态聚类统计分析方法从不同方向进行数量分类,并对数量分类成果用判别分析进行检验。最后对各县域每km2和每万人负荷古树数进行核算,用数据资料说明县域保护古树的重要性,增强县域保护古树的责任感。
The research object is limited to 30851 ancient trees scattered in the mountainous areas and villages in Jiangxi Province. It does not involve the ancient trees in nature reserves and forest parks. According to the growth characteristics of ancient trees, the temporal distribution (old tree level and age), the spatial distribution (city-area distribution and county distribution) are analyzed, and the quantity classification is conducted from different directions by means of dynamic cluster statistical analysis. Discriminant analysis test. Finally, count the number of old trees per km2 and every 10,000 people in each county, and use the data to explain the importance of protecting the ancient trees in the county and enhance the responsibility of protecting the old trees in the county.
