Research on Functional Value Estimation and Development Mode of Green Infrastructure Based on Multi-Dimensional Evaluation Model: A Case Study of China

With the rapid development of urbanization and industrial economy, urban green space and land resources have been squeezed. The problem of urban ecological environment pollution is becoming increasingly serious. With the concept of sustainable development, green infrastructure construction can not only improve the adverse effects of human activities on the urban ecological environment, it can also deal with the relationship between survival and development, economy and the environment, society, and resources. This paper used different provinces and regions of China as an example to construct a multi-dimensional evaluation model. The multi-function green infrastructure was evaluated quantitatively from three dimensions: economy, society, and ecology. The study results showed that the multifunctional development level of green infrastructure varies among different regions in China due to regional location, economic development, and natural resources. The development mode of green infrastructure in North China, South China, and Northwest China has changed from multi-functional weak and basic coordination to strong and coordinated development. Therefore, the multi-dimensional analysis of green infrastructure is helpful for systematically studying and evaluating the functional value of green infrastructure. It can be used to investigate the development models of green infrastructure in different regions, formulate green infrastructure development strategies, and provide countermeasures and suggestions for relevant government departments.
