Oasification in Arid and Semi-Arid Regions of China: New Changes and Re-Examination

Abstract

The “counter-trend” of oasification in China’s arid and semi-arid regions has attracted widespread attention against the backdrop of the rising global desertification risk, which endangers ecological safety and food security. This paper selects the pertinent literature from the CNKI and the WoS core collection databases and then uses bibliometric methods to comb the current status, key contents, and cutting-edge trends of oasification research. The following conclusions are drawn: (1) Compared to desertification research, research on oasification has not been sufficient and the understanding of oasification has not been raised to the same level of importance as desertification; (2) From the perspective of the literature, the oasification research hotspots have gone through four stages: “spatial and temporal evolution, ecological effects, driving mechanisms and sustainable development paths”; (3) Current research on oasification is mainly focused on the evolution of landscape dynamics, sustainable development, and ecological conservation. Research outlooks are as follows: (1) From the perspective of system theory, we construct a theoretical framework of “man and nature” harmonious community, and systematically study the alternating evolution process of “desert–oasis” in arid and semi-arid regions, and its effects; (2) The synergistic factors, development mechanism and preferred path of oasification sustainable development should be some of the key contents of future research; (3) Oasification management in arid and semi-arid regions is not the opposite of desertification management, and research on the oasification governance system, governance content and governance mechanism is necessary.
