Water-soil conservation services dynamic and its implication for landscape management in a fragile semiarid landscape

Under the influence of climate change and human activities, the sustainable management of water and soil resources has been an important issue, especially in arid and semiarid regions. In this study, we first coupled the water-soil conservation service assessment with the ecohydrological processes m...
