Using Remote Sensing to assess sustainable development on a Chinese National-level New District

摘要

The changes of land use affect the sustainable development of society through its influences on the interactive balance among the population, resource, environment and ecological development. In the process of Chinese urbanization, increasingly serious contradictions between human and land have been caused by the dramatic increase in the demand of land resources. This paper used a case study on Guian New District, which is a national-level new district in China. The research focused on the change of land use in the new-style urbanizing process of Guian New District. The sustainable development in this district was analyzed by applying the technology of Remote Sensing and Geography Information System to collect the spatial data of land use in 2010 and 2018 of Guian New District, utilizing the theory of ecosystem service value to obtain quantitative description of the ecological outcome of land use, and comparing the variance in land use and ecological benefit before and after the establishment of Guian New District. The study has shown that the land use of Guian New District almost meets the basic requirements of sustainable development. Furthermore, in order to achieve sustainable development in this district, suggestions were provided on how to improve the structure and location of land use, as well as taking account of the impacts on the long-term ecological benefit.
