SITE CLASSIFICATION FOR PROTECTIVE FOREST AFFORESTATION ON THE COAST OF CHINA

Land for protective forest on the coast has special site conditions,and siteclassification is the scientific basis for seaboard afforestation.The site classification systemon the coast zone and islands of China may be classified into five levels-site region(sub-region),district,class,group,and type.The land division for afforestation is carried outby the principle of enviornmental heterogeneity among regions,sub-region and district onlarge scale,according to the difference of air temperature,moisture and type of coastgeomorphy.It may be classified into 7 regions,12 sub-regions and 55 districts.Themedium and small scaled division for site class,group and type,subdivided in a sitedistrict,are based on medium topography,topographic climate,micro-relief and soil conditions.

Site classification for protective forest afforestation on the coast of China

Land for protective 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-site region (sub - region), district, class, group, and type. The land division for afforestation is carried out by the principle of enviornmental heterogeneity among regions, sub-region and district on large scale, according to the difference of air temperature, moisture and type of coast geomorphy. It may be classified into 7 regions, 12 sub-regions and 55 districts. The medium and small scaled division for site class, group and type, subdivided in a site district, are based on medium topography, topographic climate, micro - relief and soil conditions.
