摘要城市绿地作为人类生活与生存必要的基础与环境,同时也是城市生物多样性 的承载者,在城市生态系统中起到决定性的作用。本文引用景观生态学中有关景 观格局的概念原理,以徐州市城区为研究的对象,选用 Landsat 作为主要的数据 源,根据各项数据计算处理出徐州市城区景观绿地的面积、多样性指数及优势度 指数等各项景观指标,定量分析出徐州市绿地的格局概况,有理有据地指出徐州 市绿地景观格局的特点和问题。最终研究表明:徐州市绿地景观由于各种原因, 导致出现面积的分布不均匀、斑块结构不合理、优势度差异不明显等一系列的状 况,为了日后能发挥城市绿地更加优良的的绿化生态功能,提出了对徐州市绿地 景观格局针对相关问题改进的各类措施与对策。73821

Abstract As the necessary base and environment for human survival and living, urban green space plays a decisive role in urban ecosystems ,it’s also the carrier of urban biopersity. Referring to the principles of landscape ecological concepts related to landscape pattern and the primary data source from the Landsat, this article reasonably points out characteristics and problems of Xuzhou green pattern after quantitatively calculating and analyzing the area, persity and dominance index and other landscape indicators. The final results show that: various reasons result in uneven distributional area, irrational plaque structure and none obvious advantage in Xuzhou green space. In order to fully make green space in Xuzhou function as green ecological role, the article puts forward all types of suggestions and countermeasures to improve the above-mentioned problems of landscape pattern in Xuzhou.
