摘要
On the basis of investigating the current situation of the urban greenland system in Zhuzhou by utilizing 3S technology,author analyzed the landscape structural characteristics of the urban greenland system in Zhuzhou. The results showed the degree of fragmentation of landscape in Hetang District was the highest and the area of the biggest patch in Tianyuan District was smaller. The interior ratio in Central Square was the best, and the isolation in Yandi Square, Changjiang Square and Xiangshi Square were good. The connectivity of urban green system in Zhuzhou was relatively poor. The diversity index, evenness index and superiority were respectively 1.47, 0.57, 1.11 in Zhuzhou. Lusong District had the lowest diversity index, evenness index and the highest dominance. Some advices against above-mentioned problems were put foreward.
