Abstract  

The coastal protective forest in Quanzhou bay was extracted and the change detection technique was employed to reveal the change of coastal protective forest in Quanzhou bay from 1987 to 2008,and the scientific decision making was provided for forest construction and protection.This paper employs the decision tree classification of remote sensing technology to extract the coastal protective forest.The results shows that a total of 537.23 hm2 coastal protective forests have been increased from 1987 to 2008,the main protective forests are Broadleaved forest,account for 70%~80%.On the whole,the Broadleaved and coniferous forest both increases continuously,and the mangrove decreases in the first 9 years and increases in the later 21 years; but protective forests decreases in local areas,especially in Fengze district,because its spatial expansion occupied large area of protective forests.Though the protective forests in Quanzhou bay increase to some extent,their spatial distribution are incompletely reasonable.Therefore the protective forests in Quanzhou bay can not protect Quanzhou coastal developed region effectively.

Key words:  Decision tree classification      Coastal protecting forest      Change detection      Quanzhou Bay      Remote sensing
