Abstract:

In order to carry rationally out forest landscape planning and construction,the landscape ecological sensitivity and landscape visible sensitivity of Jiufeng urban Forest reserve in Wuhan City were studied based on RS and GIS technique integrated subcompartment investigation.The results showed that,the high ecologically sensitive areas accounted for 46％ of the total area of Jiufeng urban forest reserve in Wuhan City,and included the barren hills,the abandoned quarry and a small amount of brushwood.The ecologically restoration of high ecological sensitive areas should be conducted as soon as possible.The moderate ecological sensitive areas accounted for 535％ and included water body,cultivated land,some forestry nurseries and construction sites which might focus on the forest vegetation restoration and landscape construction.The low ecologically sensitive areas accounted for 419％ and included forest cover region,some forestry nurseries and residential areas,which should be protected with particular importance.The firstclass visually sensitive areas were mainly distributed in the closeshot zone of the both sides along the roads with more than 20° slopes,which should be taken measures to protect and restore the landscape.The secondclass visually sensitive areas mainly were the smaller slope closeshot zone,and mediumshot zone and wideshot zone of all mountains,which had strong visibility and should actualize landscape reconstruction.The thirdclass visually sensitive areas mainly were the smooth mediumshot zone and wideshot zone,and included the seminatural landscape and cultural landscape of cultivated land,forestry nurseries and residential areas,which could develop landscape construction without affecting the overall appearance and visual environment.The fourthclass visually sensitive areas were the invisible or low visible regions with lower slope and worse accessibility,which should not arrange construction projects.
