Abstract: Habitat fragmentation and biological process obstruction are the major threats to the biodiversity in urban areas. In current urban biological conservation planning, there exist some deficiencies e.g., the species-centered approach pays little attention to the regional habitat pattern, and the landscape-oriented method lacks the consideration of biological process. Therefore, an integrated approach combining the biological processes and habitat patterns of selected species is highly advocated by advancing theories in conservation biology, landscape ecology, and landscape planning. Taizhou, a rapid urbanization area with rich biological resources in Zhejiang Province of southeastern China, faces heavy habitat fragmentation and biodiversity loss during the recent dispersed urbanization process and intensive infrastructure construction. This paper combined the knowledge of biological processes of indicator species and the design of regional landscape patterns. Two kinds of bird were selected as indicator species, i.e., Larus saundersi, a typical migratory bird temporarily feeds in the mud beaches of Taizhou, could be thought of as a type of biological behavior of vertical habitat selection process, and Syrmaticus ellioti, one of the major resident birds of this area, has both vertical habitat selection and local migration behavior. The methods of analyzing landscape suitability and security pattern were employed to distinguish the appropriate habitats of the two indicator species based on vertical  and horizontal processes, and finally, a comprehensive biological conservation infrastructure was obtained by overlaying them, which could provide references for similar urban areas to Taizhou.
