福建中段岛屿沿岸植被的初步调查

COASTAL VEGETATION ON ISLANDS ALONG THE CENTRAL FUJIAN COAST (SHENGFU BAY TO MINJIANG ESTUARY)

1963年5月至1964年7月,作者在福建海岸带中段(深沪湾——闽江口,24°41′—26°1′30″N)的红树林调查过程中,同时对该段的大坠岛、湄洲岛、鹭鹚屿、南日岛、小日岛、野马屿、江阴岛、文关岛、塘屿、草屿、牛山岛、东庠岛、平潭岛、大板岛、大练岛、小练岛、东壁岛、屿头岛和吉兆岛等(见刚图)20个岛屿的沿岸植被进行了一次初步调查。调查范围自高潮线向陆延伸两公里左右。在调查过程中,由于受时间等原因的限制,采集尚欠全面,加之有关岛屿的参考资料缺乏,错误之处难免。但作为这些岛屿沿岸植被的首次调查,其资料对同行及将来研究具有一定参考价值。

Altogether more than 700 samples of vegetation were collected from the field investigations.They are composed of 170 species belonging to 153 genera,63 families.Plants based on the taxonomic system in correspondence with niches and collection sites as well as the natural survey of 20 islands are provided.The moisture of the niches is one of the controlling factors in determining the diversity and the features of coastal vegetation,such as hilly area vegetation,damp area vegetation and cutured vegetation.The differences in the landscapes of plants in the northeastern and southwestern sides of an island are discussed.
