Abstract: We take the Jinshui District of Zhengzhou as the object of research. and select Pica pica, Carduelis sinica and Sturnus cineraceus as representative birds species. We quantified the urban green patches by calculating the integral index of connectivity (IIC), probability of connectivity (PC) and the important value of different green patches for connectivity (dX). The study shows that the overall level of landscape connectivity within the region is low, the green patch is positively correlated with the integral index of connectivity and the probability of connectivity, the position of the patch will affect integral index of connectivity, and 'absolutely important' green patch size is about 7.7 km². This study provided reference for the construction and regulation of Zhengzhou green space resources and planning of animal corridors and habitat isolation of invasive species.
