Abstract

Ecological restoration of territorial space is an important measure to implement the concept of ecological civilization construction, and accurately identifying ecological restoration areas is a difficult point in carrying out the ecological restoration of territorial space. Taking the Chang-Zhu-Tan metropolitan area as the research area; we used methods and models, such as the water balance equation, InVEST model, and circuit theory; combining ecological degradation risk assessment with ecological security pattern construction; accurately identifying the ecological conservation area and ecological restoration area of the ecological source area, ecological corridor, and stepping stone; and proposed strategies for ecological protection and restoration of national land space. The results indicated that: ① The ecological degradation risk in the study area substantially showed a "medium high and low weekly" spatial pattern. ② A total of 74 ecological source areas were identified with a total area of 5 425.21 km2, 170 ecological corridors with a total length of 1 608.26 km, and 78 stepping stones with a total area of 24.35 km2. A source restoration area of 105.98 km2, corridor restoration area of 643.25 km, and stepping stone restoration area of 16.59 km2 were diagnosed. ③ We constructed an ecological network spatial pattern of "one heart, one ring, and one barrier" in the Chang-Zhu-Tan metropolitan area, including the green heart, ecological middle ring, and peripheral ecological barrier. ④ Based on the identification result of ecological restoration of territorial space and combined with the actual situation of the research area, differently oriented ecological protection and restoration measures have been proposed, and a collaborative cross regional restoration mechanism of "governance-management-supervision-early warning" was formed. The research results are helpful for the formulation and implementation of ecological restoration of territorial space plans and measures in the Chang-Zhu-Tan metropolitan area and can also provide scientific methods for ecological protection and restoration research in other similar areas.
