In environmentally sensitive areas, particularly the arid or semi-arid regions, different factors such as relief and human activity, can greatly influence the landscape on a local scale. Using satellite imageries and field investigations, we have studied the distribution of sand dunes in the Maowusu (Mu Us) Sandy Land in the southern Ordos Plateau, northern China. Key research questions are which...
This chapter briefly reviews the terminological origin, development and the latest status of desertification and demonstrates the significant impact of the climatic variations in the processes of desertification and its rehabilitations. Two typical arid regions at Asia’s middle latitudes are selected as cases for studies, i.e., the oases in the hyper-arid Taklamakan Desert in the west and the semi-arid...
Despite decades of research, fundamental questions remain about how China's deserts and desert margins function, how they interact with regional and global scale environmental systems, and how they have responded to recent natural and anthropogenic forced climate change. The predominant focus of desert research in China, and globally, has been site specific case studies within sub-disciplines. This...
Assessment of the dryland vegetation change and identifying its causes are of great importance for combating desertification and projecting future ecosystem dynamics in arid and semiarid regions. Since plant growth in temperate drylands is constrained by both water and temperature, understanding how ongoing warming climate will impact temperate vegetation of the steppe and fixed dune fields is a crucial...
