Abstract : Blue-green spaces composed of water and green spaces
have certain ecological, economic, and social benefits for urban
development. Many evaluation index systems have been developed to
evaluate the health status of urban ecosystems. However, in these
evaluation index systems, blue and green spaces are separately evaluated
without considering the synergistic effect between water and green
spaces in the ecosystem, thus affecting the unified planning and
construction of cities. Therefore, based on existing studies, the
development process of the blue-green space evaluation index system is
divided into three stages: supply service evaluation stage, adjustment
service evaluation stage, and cultural service evaluation stage in order
to deeply discuss the development path of the blue-green space
evaluation index system. The single blue and green evaluation index
systems are compared from the perspectives of index selection and
evaluation content. Moreover, the characteristics of conventional
evaluation methods are discussed in order to propose an applicable
evaluation index system and evaluation method of blue-green spaces for
evaluating the degree of blue-green integration of cities. The review
provides the basis for urban planning and ecological restoration.
Key words : blue-green space; evaluation index system;
