Advances in the blue‐green space evaluation index system

Abstract

Blue-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, 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 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.

Sustainable Urban Green Blue Space (UGBS) and Public Participation: Integrating Multisensory Landscape Perception from Online Reviews

“…Artificial park systems, urban forests, or river courses after treatment and landscape transformation in the built environment can provide a multifunctional UGBS for residents, which is important for BGI in the city [24]. In addition to protecting urban ecology, citizens can perceive nature and recover psychologically by visiting or passing urban greenways and street green spaces while commuting [25][26][27]. UGBSs, such as parks in the city, also carry out social and cultural functions and are, therefore, very important functional spaces in the city [7,28,29].…”
