Spatio-temporal variation of oasis landscape pattern in arid area: Human or natural driving?

The eco-environment of the arid area is constantly fragile global-wide. The study on the spatial and temporal variation of its landscape pattern can quickly identify the driving factors, which is an effective analysis method of ecological conservation in the arid area. In this study, Jinghe County,...
