The geographic distribution and floristic characteristic of Magnoliaceous 7 genera and 23 species in Jiangxi are studied in this paper.

摘江西木兰科植物7属23种的地理分布和区系特征行了分析。

Gray clustering is a feasible method to assign these floristics to their suitable area, in which assorting vegetable and delineating the clustering objects by linear features are necessary.

在分区中利用各级线性地物划分象，并种繁多的植物简分十分重。
