摘要
以高分辨率遥感影像为主要信息源,在地理信息系统(GIS)和景观格局软件(Fragstats3.3)的支持下,运用景观生态学的理论,对宁波市鄞州区的首南街道、钟公庙街道、中河街道城市景观空间结构进行分析。根据宁波市鄞州区的城市结构特点,将研究区的城市景观分成8类。对研究区城市景观的空间组成、空间属性、空间关系进行分析,并利用GIS对研究区的绿地景观进行生态影响范围的分析。结果表明:首南街道公共建设景观和农业景观斑块面积比例最大,基本满足其作为鄞州区行政中心的城市职能,城市生态环境水平较高;钟公庙街道工业景观较复杂,景观破碎化程度较高,产业调整以及旧城改造是提升其生态环境质量的有效途径;中河街道居住景观面积在3个街道中最大,居住景观较复杂,人口密度最高,而软质景观比重较少,城市生态环境水平较低,需要加强软质景观的建设,增加城市绿地的比重。
Based on high resolution remote sensing data as the main information source,the geographic information system（GIS） and landscape structure software（Fragstats 3.3）were used to analyze landscape patterns of the urban spatial structure in Yinzhou district of Ningbo in terms of the fundamentals of landscape ecology in this paper.According to the character of Yinzhou district of Ningbo＇s urban structure,the urban landscape was assorted into eight types.This paper investigated landscape composition,spatial attribute,and spatial relations of the landscape types,and also studied the ecological impacting scale of green landscape with the aid of GIS.The result shows that among three subdistricts in Yinzhou district,the public construction and agriculture landscape of Shounan subdistrict have the highest area percentage,and the spatial pattern basically suits to the urban function as administrative center of Yinzhou district,with relatively higher ecological environment.The industry landscape of Zhonggongmiao subdistrict is relatively complex and has a higher degree of landscape fragmentation.The industrial restructuring and transformation of the old urban facility would be the effective measures to enhance the quality of the environment.The residential landscape in Zhonghe block has the largest area,with relatively complex landscape,and the population density in this subdistrict is highest.However,there is relatively small proportion of soft landscape,and a lower level in urban ecological construction,therefore it is necessary to strengthen the construction of soft landscape and increase the proportion of urban green space.
