Analyses of variation in quantity of Jankowski 's Bunting

分析结果显示，无论是栗斑腹鹀的数量还是鸟类物种数，都并不与斑块面积显著相关，还受栖息地空间异质性、人为干扰等因素的影响。

The analytical results showed that neither quantity of Jankowski 's Bunting nor number of birds species significant correlated to areas of the patches , both of them were influenced by human disturbance and habitat spatial heterogeneity .
