CENGAGE Learning:
The process through which a desert takes over a formerly non-desert area. When a region begins to undergo desertification, the new conditions typically include a significantly lowered water table, a reduced supply of surface water, increased salinity in natural waters and soils, progressive destruction of native vegetation, and an accelerated rate of erosion.
Example sentences:
In addition to vegetation deterioration, erosion, and salinization, desertification effects can be seen in loss of soil fertility, soil compaction, and soil crusting (DESERTIFICATION OF ARID LANDS)
Common indicators of desertification include a reduction in the amount and diversity of plant and animal species, loss of water-retention capacity, lessened soil fertility, and increasing wind and water erosion. (Desertification)
Desertification creates conditions that intensify wildfires and stirring winds, adding to the tremendous pressure to earth's most precious resource, water, and, of course, the animals dependant on it. (Did you know?)

Desertification一词的含义系指荒漠化,在我国由于传统和习惯的原因被译成沙漠化。实质上沙漠化是沙质荒漠化,系荒漠中的一种类型,是狭义的概念。联合国文件中译文中的沙漠化,按外文词义是指荒漠化,为确切起见,我们都用荒漠化。

1994年10月，世界各国政府代表在巴黎签署了联合国防治荒漠化公约，在这一正式文本中，确定了统一的荒漠化定义：“荒漠化系指包括气候变化和人类活动在内的种种因素造成的干旱、半干旱和干旱亚湿润地区的土地退化”。
Example sentences:
中国东部在全新世气候时为草原或森林草原环境,并广泛发育了富含有机质和养分的黑土层,但这层黑土层之下,即为厚层的沙层,从而构成了上述地区潜在荒漠化的沙源.上述地质特点注定了东部的黑土地地区,并非宜农区,而应当为载畜量有限的牧业区.但是,历史时期,特别是清朝光绪年间以后及民国时期,东部的黑土地被大量放垦,草场退化和土地沙化加剧.建国后的“大跃进”及“文化大革命”时期,在错误理论指导下,东部的草原地区再次掀起了史无前例的垦荒种地,及至现在,很多地区仍在进行大面积的垦荒.长期的垦荒,已经使东北的黑土地在风力的吹扬下,被剥蚀殆尽,其下的厚层第四纪沙源活化,从而使东北黑土地地区成为中国目前荒漠化危害最为严重的地区.事实上,东北草原地区的自然条件良好,水分充沛,只要政府采取措施,当地的植被是比较容易恢复的,也是治理荒漠化最为经济和现实的地区,这是干旱的西北地区所不能比拟的.但是,倘若不及时采取措施的话,中国东北的黑土地地区将沦为第2个西北.
