The suitable forest land resources in China can not meet the demand for mangroves currently,and it has become an important direction to grow mangroves in difficult sites.In this project,a planting area suitable for the growth of mangroves and semi-mangroves was created by reducing the height of river bank,creating artificial tidal creeks,using anti-scouring blankets to protect the slope,and improving the soil.The native species of mangroves and semi-mangroves were selected,and the planting method of"small community,large mixture"was adopted according to the habitat requirements of seedlings and the tidal characteristics of the planting area.About 3 hectares of mangroves have been created in Guiwan park,the core area of Qianhai cooperation zone in Shenzhen,which has achieved good ecological and social benefits and proposed a new idea for domestic mangrove afforestation.
