The effect on eco-environment and construction of landscape ecology of coastal shelterbelt system of Yantai

Coastal zone is one of the regions sensitive to global environment change.Most of the physical phenomena and ecological changes in coastal zone were caused by the construction of the coastal shelterbelt system.With the increase of population and development of economy in the coastal zone of Yantai,the exploitations on coastal zone become more intensive.Building the ecological system of coastal shelterbelt system with completing ecological function and beautiful landscape will have an ecologically notable effect.The ecological effects of the coastal protection forest on breaking the wind,fixing the quicksand,lightening the harms of storm tide and salt spray and reducing salt content of soil in the coastal zone in Yantai city were discussed in this paper.Based on the construction situation and existing problems of the coastal defense forest system,the thought and technical measures for landscape ecological construction were proposed.
