| Abstract: | The areal-types of genera of the garden seed plants in Chengdu are very complicated. As far as the origin of plants is concerned, it's rich in relic, rare, precious and peculiar species. The phenomena that temperate elements and tropic elements infiltrate each other show the transitions of areal-types of garden seed greening plants in Chengdu. Exotic species take a great proportion in Garden greening seed plants of Chengdu, maybe which leads to the problem of ecological security. |
