Remotely Sensed Ecological Protection Redline and Security Pattern Construction: A Comparative Analysis of Pingtan (China) and Durban (South Africa)

The unprecedented regional urbanization has brought great pressure on the ecological environment. Building an security pattern and guide land space development is important technique to ensure stability achieve sustainable development. In this study, Pingtan Island of China Durban city South Africa were chosen as case study area for a comparative different scales. importance ecosystem services sensitivity evaluated, respectively. core landscape which vital function maintenance was extracted by morphological spatial analysis (MSPA) connectivity analysis. Furthermore, sources determined combining results protection redline delimitation extraction. potential corridors identified based minimum cumulative resistance model, areas constructed. showed that 42.78 km2 389.07 km2, respectively, mainly distributed in mountainous with good habitat quality. composed 15 sources, 16 corridors, 10 stepping stone patches obstacle points. total length 112.23 km, radially form “one ring, three belts”. 17 11 18 274.25 “two rings research can provide reference construction planning restoration projects Durban.
