As far as the relationship between gmnr flora and other flora outside of guangdong province, the analysis shows that gmnr is more similar to jianfengling than to lushan mountain an jiulong mountain. so, the author thinks gmnr is floristically a transitional zone from the tropic to subtropic, and it should be a part of east - asia region, belonging to the " paleotropic kingdom "
同時，與省外地區植物區系的比較結果表明，古兜山等廣東地區與與熱帶區系海南尖峰嶺植物區系的聯系比與中亞熱帶植物區系的廬山、九龍山植物區系的聯系要密切些（甚至強于與車八嶺植物區系的聯系） ，進一步證明了本植物區系熱帶向亞熱帶過渡的性質，為華南省植物區系的組成部分，隸屬于古熱帶植物區。 -
On comparing the composition of its flora with some neighbouring floras, gmnr is most similar to lianhua mountain and dinghu mountain, the representative flora of the " southern subtropical region ". the tropical elements in gmnr flora are obviously less than those in the jianfengling flora which is the " northern tropic region ", and the temperate ones less than those in the lushan mountain flora and the jiulong mountain flora, the representative flora of the " middle subtropical region ". as shown by the coefficient of similarity of flora and the clustering analysis of geographical elements, gmnr flora has a close relationship with others in guangdong, such as the flora of lianhua mountain, dinghu mountain, qimuzhang and chebaling, and the influences of tropic elements on those flora become less and less with the latitude ' s increase
本文通過區系相似性系數比較和地理成分聚類分析，認為古兜山與蓮花山、鼎湖山、七目樟和車八嶺植物區系的聯系都很密切，廣東植物區系受熱帶成分的影響有從低緯向高緯、由沿海到內陸逐漸降低的趨勢：古兜山植物區系受熱帶成分入侵最為強烈，蓮花山和鼎湖山受熱帶成分的影響有所降低，七目樟植物區系受熱帶成分的影響進一步降低，車八嶺植物區系受熱帶成分的影響最弱。
