Abstract: Taking the Yiyang City, a typical landscape resource-based city, as the study area, Morphological Spatial Pattern Analysis (MSPA), circuit theory, human footprint model and hydrological analysis are used to identify its ecological security pattern and thus to propose optimization measures. The results showed that:(1)The ecological source areas of Yiyang city was 3 365.31 km², accounting for 27.36% of the total area of the study area, of which the important ecological source areas were mainly located in Anhua County and Taojiang County, and the key restoration ecological source areas were mostly in Anhua County but not large in area, and it is also found in Yuanjiang City and Nan County, which is mainly distributed in areas with frequent human activities. Sixty-one ecological corridors and 125 ecological nodes were identified. In addition to the Zishui chain ecological corridor, there are 7 key ecological corridors and 53 general ecological corridors with a total length reaching 509.55 km. (2)Based on the distribution of ecological source, ecological nodes and ecological corridors, the ecological security pattern of "two zones, one chain plus multiple corridors" in the study area was identified, and on this base, optimization measures such as adding two ecological sources and opening up ecological corridors were proposed.
