Landscape pattern analysis of Yinzhou new city zone based on high spatial resolution aerial photos
摘要
Abstract
With urban spatial analysis combined with some metrics, this paper attempts to quantificationally analyze the landscape pattern of Yinzhou new city zone, an important region in the development of Ningbo central district in Zhejiang Province, based on the land use of Gis-datasets derived from 1 : 5 000 high spatial resolution aerial photos of 2009. According to the theory of landscape ecology and the characteristics of study area, the urban landscape was classified into 6 types, namely, hard surface, water, public green, protective greenbelt, agriculture, and road in this paper. Applying the spatial pattern analysis software FRAGSTATS 3.3, this paper includes these following four aspects: (1) urban landscape structure of patch; (2) class-level metrics of landscape types; (3) landscape-level analysis; (4) patch size distribution. The results show that there are numerous and well-proportioned landscape components in Yinzhou new city zone, which has formed the massive isotropic landscape in the progress of urbanization. Land used for construction occupies 49.96% , mainly in the northern region, along north of the Yinzhou Road. Agriculture, with an area of 1 785.51 hm2, occupies 23.9%, mainly along south of the Yinzhou Road. Water network, crowded and distributed evenly, is a typical model with urban features in south of the lower reaches of the Yangze River. The hard surface which has higher landscape fragmentation is complex and is most obvious in human disturbance. Among three kinds of urban green, the public green displays higher patch density with the edge density of 8.22 and 76.65 respectively. This indicates that the public green is quite seriously fragmented and complex; but the agriculture, concentrated in southeast of Yinzhou new city zone, is more unitary, and the patch density and the edge density is lower, with 2.34 and 41.46 respectively. Each type is predominantly the small size patch, taking up 71.01%. The patch distributions at mesoscale level or above are few. The agriculture has a higher mesoscale patch and a bigger scale patch, occupying 35.43% and 30.29% respectively. 73.94% of public green patch is identified as small scale patches with less than 1 hm2 of the area.
