| 摘 要(英文)：The coastal Sandy soil has been improved and exploited by engineering and biological methods at Tianxin Agricultural and Forestry Farm in Chaoyang since 1959. Casuarina equisetifolia protection forest of 100 - 200 m in width was planted near the sea, while Shelter forest netWork of 50 × 50 m checks was constructed close tO the protection forest. Crops and fruits were planted within the network . The comprehensive exploitation of the Sandy land has brought about the development of biodiversity, the xeric plants in coastal degraded land have been replaced by the sciophyte species. The investigation also shows that the structure, physical and chemical properties and fertilization of soil have been greatly improved . It is considered that the forest network can increase the fertility of soil, improve the microclimate, and increase the economic benefits for local people. The measures of exploitation must suit the natural, social, economic conditions and meet the demands of the land owners. |
