武汉市九峰城市森林保护区景观敏感度评价

摘要/Abstract

摘要：

为合理开展森林景观的规划与建设，应用RS和GIS技术，并结合小班调查，对武汉市九峰城市森林保护区的景观生态敏感度和景观视觉敏感度进行了研究。结果表明：在武汉市九峰城市森林保护区中，高生态敏感区面积占总面积的4.6％，主要包括荒山、废弃采石场和少量灌木林地，应尽快进行生态恢复。中生态敏感区面积占总面积的535％，主要为水域、农田、部分苗圃和建设用地，可重点开展森林植被恢复和景观建设。低生态敏感区面积占总面积的419％，主要是森林覆盖区域、部分苗圃和居民点，应重点加强保护。一级视觉敏感区主要分布在沿道路两侧坡度大于20°的近景带，应以保护和生态恢复措施为主。二级视觉敏感区主要是坡度较小的近景带和山体的中、远景带区域，可视性强，应重点开展景观改造。三级视觉敏感区主要是中、远景带中的平坦地带，包括农田、苗圃、居民点等半自然景观和人文景观，可在不影响整体风貌和视觉环境的前提下进行景观建设。四级视觉敏感区为不可见区域或低可见区域，坡度大，可及性差，不宜规划建设项目。

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.

Key words: urban forestry reserve/landscape sensitivity/visible sensitivity/ecological sensitivity
