Biodiversity Assessment and Conservation in SEA of the Coastal Economic Zone in Liaoning Province, China

Wetland has an important value on biodiversity conservation in the Liaoning coastal area. In the SEA of Liaoning coastal economic zone, four indices of biodiversity assessment are proposed based on the principles of scientificity, representativeness, and practicality, in which the indices proposed are species richness, diversity of ecosystem types, species endemism, and extent of biological invasions. Methods for biodiversity assessment are established, and the biodiversity of the coastal area is assessed. Biodiversity was classified into four grades. The assessment results show that there are highly rich biodiversity in six coastal cities and four coastal nature reserves of Liaoning Province. Measures and suggestions for biodiversity conservation are proposed for the Liaoning Coastal Economic Zone development decision-making, which can promote sustainable development in this region.
