Construction of an ecological security pattern based on functional wetland theory: A case study in a landscape city

The high-intensity development of a city encroaches on the ecological land, such as lakes, rivers, and forests, which changes stable land relationship, resulting in security problems, regional waterlogging decline biodiversity. Identifying urban systems constructing patterns (ESP) are great importance for protection spatial planning. complexity environment landscape cities makes them more difficult planning construction than plain cities. Additionally, they susceptible to torrential rains, mountain torrents, river tides process urbanization. This study introduced functional wetland theory into ESP obtained new set methods Based theory, “patch-corridor-matrix” model was used combine geographic information system (GIS) runoff catchment analysis with MSPA-MCR corridor method form habitat network by coupling two together. principles priority, maximization benefits, guarantee connectivity, targeted design guide were put forward. takes central area Fuzhou an example show application path this method.
