Abstract:

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.

Key words: spatial structure, green space, Yinzhou district of Ningbo
