<正>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。

Land for pretected forest on the coast has special site conditions, and site classification is the scientific basis for seaboard afforestation. The site classification system on the coast zone and islands of China, may be classified into five levels梥ite region (sub-region ) , district, class, group, and type. The land division for afforestation is carried out by the principle of environmental heterogeneity among regions on large scale, according to the difference of ail temperature, moisture and type of coast geomorphy. It may be classified into 7 legions, 12 sub-regions and 55 districts. The medium and small scaled division for site class, group and in type, subdivided in a site district, are based on medium topography, topographic climate, micro-relief and soil conditions.
