摘要
辽东潮间浅滩是我国淤泥质海岸的重要组成部分。因位处海陆结合部,承受海水周期性浸淹,故兼有海洋与陆地的物理、化学和生物学等共同特征。因此,潮间浅滩是一个特定的生态系统,构成完整的自然综合体。
The Liaodong Peninsular tidal flat is an important mud coasts in China.As it is situated between sea and land,it has the common characteristics of physical,chemical and biological from both sea and land.Therefore,it is a good place for the proliferation of benthos,meanwhile,it also provides the great potentialities in the redaima-tion of land from marshes,reed planding etc.The characteristics of present trends of the tidal flat are the aggradation of flat surface and push the coast line forward toward the sea.From the coastal zone investigation,it revealed that the Liaodong tidal flat is effected by different currents,the author according to the diversities of biotic composition,micro-landforms and types of sediment,three sub-belts of flat is suggested:1.Suaeda Glauca Bun-ge,Macrophthalmus Dilitatus De Haan-animal-inhabited mud pile-high tidal mud belt.2.Zostera Marina L.,Ruditapes Philippinensis(Adams et Reeve),Bullacta Ex-arata(Phillppi)-scaly beach-middle tidal silt belt.3.Ruditapes Philippinensis(Adams et Reeve),Dosinin Traillei Adams,Cyclina Sinensis(Gmelin)-wave and current ripples-low tidal fine sand belt.On the bases of the biotic environment,rational development and according to different altitude,the tidal flat can be divided into three belts:1.The economic shellfish cultural belt 2.The planting reed belt,3.The rice planting belt.
