马鞍山市河岸带景观格局分析研究

本文应用3S技术,基于地理信息系统平台及结合实地勘查,以河道宽10倍作为河岸带范围比较分析马鞍山市建成区4条河流(慈湖河、采石河、雨山河、永丰河)河岸带土地空间特性及景观格局。结果表明:该市河岸带比重大,占研究区的20.73%,总体上以建筑及农田用地类景观为主,两者的斑块平均面积大;绿地景观比例小、尤其是滨水绿地少,未见自然的河岸植被带,河岸带的生态功能弱。比较4条河岸带景观,位于近郊的河岸带景观丰富度及均匀性均高于市区河流、优势度低于市区河流。作者建议在适当增加河岸带的绿地面积的同时更应提高滨水绿化率,可参照永丰河的绿化水平,将河岸带绿地率增加至7%左右,同时提高滨水绿化率至6%以上。

Study on Landscape Pattern of Riparian Zone in Maanshan

The 3S technology combined with field investigation was employed in this paper to make an analysis on both of land use and landscape patterns of Riparian zone for four rivers(Cihu River,Caishi River,Yushan River and Yongfeng River) in Maanshan city,which was defined as 10 times as wide as river course. The results showed that the riparian zone covered 20.73% of total land area,building and agricultural land categories were the main landscape,and had larger average area of patches;green land had small percen...
