Abstract:

The bird community was surveyed in Shanghai Botanical Garden, Century Park, Gongqing Forest Park, Binjiang Forest Park and Haiwan Forest Park during May 2012 to April 2013 by line transect method. We used ArcGIS 10.0 to classify the patches within the urban parks by visual interpretation. Based on the classification, 34 patch variables including patch number, patch density, patch area and patch total edge was set to analyze the relationship between bird communities and patch variables. We used Chi-square test to analyze whether the bird species and abundance in various urban parks differed significantly. Multiple statistical analyses were required to measure how the patch variables affected the bird community composition. Results indicated that there was significant difference among bird richness, bird abundance, the number of patches in 5 urban parks. Multiple linear regression models confirmed that there was significant positive correlation between bird species and the number of Number of Water patches (WNP) and Grassland patches shape index (GSI ). There was significant negative correlation between bird species and the largest patch index (LPI ). Bird abundance was significant positive correlation with size of Plant patches (PPS), mean size of patches (MPS) and was significant negative correlation with total edge of Plant patches (PTE). In addition, suggestions in relation to the construction of urban parks and vegetation configuration were put forward according to the above results.

Key words: urban parks, patch structure, bird community, multiple linear regression
