本文应用综合分析的方法，在回顾沿海防护林体系历史的基础上，着重论述了沿海防护林体系的“网片带点”结构和降低区域性风速、调节区域性气候、减弱飞盐危害、加固海堤安全、提高土壤肥力、保护农作物丰产稳收、增加生物多样性等功能；提出了沿海防护林体系背负的使命和发展中的问题及对策。

The Strucure,Function and Developing Tendency of the Coastal Windbreak System

Using the method of integrative analysis,on the basis of the historical review in the coastal windbread system, the paper discussed the functions of the structure of "network,part of district,belt and point"of the coastal windbrdak system. The coastal windbreak system reduces the field wind speed, adjusts the field weather,decreases the damages of flying salt,strengthens the safety of coastal bank,promotes the fertility of soil,protects the good and stable products of crop and increases the diversity of organism and so on. It points out the mission of coastal windbreak system, the problems in development and the countermeasures.
