恩施州乡土园林植物开发利用之我见

恩施地区属中国东南部低山过渡到西部高山及青藏高原的第二阶梯,地形复杂,海拔67—3000米,属北亚热带季风气候区。由于受第四纪冰川的影响较小,为中国第三纪古热带植物区系的"避难所"。由于其独特的气候条件,区内有维管植物187科1019种,其中绝大部分为具有观赏价值的园林植物。作者根据多年来对该地植物的长期考察,提出了该地区园林植物开发利用的建议,为今后恩施地区的园林绿化及花卉产业的开发提供了参考。

Some Thoughts on Development of Indigenous Garden Plant in Enshi State

Located in the transitional geographic area ranging from the China’s southeast low mountainous area to the west highland and the Qinghai-Tibet Plateau, Enshi characterizes the complicated topography with the altitude varying from 67 to 3000 meters. It is in the north subtropical monsoon climate zone. Slightly affected by the glaciers in the Quaternary Period, Enshi was the refuge of China’s palaeo tropical flora in the Tertiary period. Thanks to the unique climatic condi- tion, Enshi houses 187 vascular plant families including 1,019 species, most of which are ornamentals. Suggestions of de- veloping the indigenous plants are posed after many years’survey to give a reference to the development of landscaping and flower industry.
