Abstract The ecological restoration of land space is the key and difficult point in the comprehensive
restoration of mountains，rivers，forests，farmland，lakes and grasslands.This study can provide a method‐
ological reference for the systematic identification and restoration of key areas of ecological restoration areas
in territorial space through the construction of the ecological security pattern in the study area and the identi‐
fication of key restoration areas.Based on the diagnosis of ecosystem problems and the construction of eco‐
logical security pattern，this paper explored the method and path of identification and restoration of key ar‐
eas of ecological restoration in territorial space. The Caidian District of Wuhan City was used to systemati‐
cally diagnose the degree of degradation，the type of degradation and the spatial distribution of ecosystem
from three aspects including quantity，quality and spatial pattern. Based on the identification of ecological
sources，the ecological resistance surface is constructed with five factors of land cover type，distance from
water area，vegetation coverage，slope and altitude，and potential ecological corridors are identified by con‐
structing the least resistance model，and then the ecological security pattern is constructed.On this basis，
ecological conservation area，natural restoration area，artificial restoration area and ecological corridor con‐
struction area in Caidian District were systematically identified by integrating the diagnosis of ecosystem
problem with requirements of ecological security pattern. 1 901.52 hm² forest land and water bodies were
extracted as ecological sources，18 168.12 m potential ecological corridors were identified. Corresponding
ecological protection and restoration measures were proposed from four aspects above.
Keywords territorial space；ecological restoration；systemic governance；key areas；ecological secu‐
