海岸防护林造林地具有特殊的立地条件,其立地类型的分类是沿海造林的科学基础。我国海岸带和岛屿的造林地可采取立地类型带(亚带)、区、级、组、型的五级分类系统。海岸带(包括岛屿)造林地立地类型大尺度的分区,根据气温、水分条件、海岸类型分为7个带12个亚带55个区。级、组、型为中、小尺度的分区,根据各立地类型区的中地形、小地形、地形气候以及土壤条件等具体划分。
Coastal shelterbelts afforestation has a special site conditions, the classification of its site type is the scientific basis of afforestation along the coast. China’s coastal zone and island afforestation can take site type (sub-zone), area, level, group, type five classification system. Large-scale zoning of afforestation land in the coastal zone (including islands) is divided into 7 zones with 12 sub-zones and 55 zones according to the temperature, water conditions and coastal types. Levels, groups and types are classified into medium and small scales according to the topography, small topography, topography and soil conditions in each site.
