摘　　要：选取2010年、2020年西安市地表覆盖数据,利用3S技术和景观生态学理论,分析城市景观格局变化及其生态效应。结论:2010年-2020年,西安市以秦岭林地、关中农田地景观为主的大背景格局未发生变化,城市空间连接度提高,多样性提高,区域空间格局得到优化。城市新区使水源涵养、娱乐文化功能服务价值提升,食物生产功能服务价值损失较明显,其他生态功能服务价值损失不足1%。在生态红线管控下,城市建设有效保障区域生态功能服务价值整体处于动态平衡。“北跨”时代,城市建设过程中可增加生态景观比重和空间分布,进一步提高西安市生态系统服务功能价值。Based on the land cover data of Xi'an in 2010 and 2020,3S technology and landscape ecology theory were used to analyze the change of urban landscape pattern and its ecological effect in Xi'an from 2010 to 2020.During the period,the general background pattern of Qinling forest and Guanzhong farmland landscape in Xi'an has not changed,and the urban spatial connectivity and diversity have improved,and the regional spatial pattern has been optimized.The value of water conservation,entertainment and cultural functions increased in new urban areas,while the value of food production functions lost significantly.The value of other ecological functions lost less than 1%.Under the control of ecological red line,urban construction effectively guarantees the overall dynamic balance of regional ecological function service value.In the“northern span”era,the proportion and spatial distribution of ecological landscape can be increased in the process of urban construction,and the value of ecosystem service function of Xi'an can be further improved.
