| Abstract: |
| In different regions, the beach soils diversified in fundamental characters. (l) In the river mouth, deposit is dominant with mixture of sand and sludge, in the harbour the granularity appears finer, the texture is more sticky, but along coasts and islands, there are more sand and gravel. (2) Salt content is usually more than 1%, higher in harbour than along the coast and in river mouth. (3) The distributional pattern of soil nutrients in different regions appears less clear, it may be related to the mechanical composition and beach utilization. Sticky soil contains higher content of nutrients, while Sandy soil contains less. When the beach is planted with Reed and Spartina anglica Hubbard, its nutrient content will be higher than used for other purposes. Based on regional ecological conditions, beach characteristics and social economical factors, some ideas about four coast sections are put forward in this paper. |
