| 摘要: |
| 列举1986年7月21日至22日九号台风在广西沿海登陆造成的危害情况。提出,广西海岸带防护林建设从海岸滩涂向陆地伸延,应遵循海滩红树林带→海岸陆缘半红树林带→岸后季节性雨林带的带状分布规律。陆缘海岸和人工海堤的防护林应是低矮的海滩红树林和半红树林。陆域上的防风和水土保持林或固沙林是季节性雨林,宜选用当地的季节性雨林的建群种和伴生种,营造混交林,并保护林下活地被物层,形成多层结构,且与用材林分开单独经营。 |

| Abstract: |
| The seabank disasters caused by the No.9 typhoon in the coastal area of Guangxi on 21st to 22nd July 1986 are described. Some suggestions are listed as follows. The construction of coastal shelter forests should comply with the natural order of mangrove in the tidal land to semi mangrove in the backshore to seasonal rain forest in the bank. The lower mangrove should be selected to plant on the backshore and dam. The dominant and subdominant species should be selected to plant on the bank as windbreak, soil conservation forest and sand-fixation forest; and planted mixing with different species, with protection of ground cover under the forest.The protection forest should be managed separating to timber forest. |
