| 摘 要： | 在我国西南部横断山地区至云南南部一线,高山松、云南松和思茅松构成有规律的地理替代。这种替代是以生境梯度变化为基础的,针叶、球果等生物学特性也发生了相应的渐进性变化。作者认为,原始云南松适应寒冷或干燥生境而分别演化出高山松与地盘松。适应湿热生境形成细叶云南松(与思茅松有相似之处)。思茅松与云南松的关系尚不清楚。可能是原始松树趋同适应的结果。

| Abstract: | Pinus densata, p. yunnanensis and p. kesiya var. langbianensis, in southwest China, substitute gradually from north to south, forming a geographical substitute group. The subetitute group results from the environmental gradient and synchronizes with the gradual change of biological properties. The author believes that pinus densata and p. yunnanesis var. pygmaea arose respectively from the primitive p. yunnanensis in cold and dry environments and p. yunna nensis var. tenuifolia emerged in temperature--huimid environments. The relations between p. yunnanensis and p. kesiya var. langbianensis are unknowen and maybe the results of convergent adaptutjon of the ancient piones. |
