摘要:
Finding ways to identify the coupled relationship between changes in the quantity and quality of ecologically functional land (EFL) is essential for sustainable ecosystem management. However, this coupled relationship has been ignored in the literature. This paper proposes a quality-based quantity (QBQ) method to evaluate the spatiotemporal change in EFL in China. Three Landsat images spanning 20 years were used to investigate the gains and losses of EFL. We compared the differences and linkages between the net change and QBQ change of EFL at the county scale. Continuous EFL loss and growing f...
