Nebkhas play important roles in desertification control and biodiversity protection in arid and semi-arid regions of China

Nebkhas are isolated mounds vegetated with burial-tolerant desert plants that trap windborne sediment within their canopies. Nebkhas are critical to desertification control and biodiversity protection of oases in arid and semi-arid regions of China, as they (ⅰ) trap windborne sediments and ensure oa...
