Evaluation of urban land resource value based on sustainable environment space governance

For any cities, the optimal objective of development is to fully tap the value of land resources, while pursuing the progress of economy, society, and eco-environment. Currently, there is not yet a unified evaluation standard for sustainable development quality of urban environment; the land resource value has not been deeply evaluated from the three aspects of society, economy, and eco-environment. Therefore, this paper tries to measure urban land resource value based on sustainable environmental space governance. Firstly, the authors constructed a scientific evaluation index system for sustainable development quality of urban environment. Next, a comprehensive evaluation method was developed for sustainable land utilization in urban space governance system. After that, the urban space governance scheme was subject to multi-objective optimization. Finally, experiments were carried out to measure the urban land resource value, and estimate the urban ecological service functions and their values. On this basis, the benefits of the urban space governance scheme were analyzed in various aspects. The results confirm the effectiveness of our measurement algorithm.
