荒漠化是世界上最严重的全球性环境和社会经济问题之一。本文是中国首次将科学研究与国家荒漠化决策联系起来的尝试。我们的目标是在国家防沙治沙政策和战略中追踪中国的科研成果。一个例子是自1998年以来威胁北京和天津的沙尘源头地区的大规模种植计划。有人认为，最近中国北部种植园导致的森林覆盖率增加，有助于减少沙尘暴排放，并有助于缓解北京和天津的沙尘暴天气。重新造林/植树造林政策仍然存在于中国新的国家造林规划(2011-2020年)的国家环境战略中。近几十年来的过度放牧被许多学者指责为西北地区土地退化和荒漠化的罪魁祸首，中国。小型田间试验证明，如果不受人类活动的影响，沙化/退化土地上的植被可以恢复。自1998年以来，自然恢复已成为防治土地荒漠化、恢复自然植被的一支强大的国家力量。新疆维吾尔自治区策勒县的一个例子展示了如果没有人为干预，植被如何在自然干旱和半干旱气候中大规模茁壮成长。种植园项目促使利益攸关方更好地了解其对环境的负面影响，特别是过度放牧行为。在此之后，家庭收入和生活水平也得到了显著提高；但尚不清楚该项目是否导致了劳动力移徙。版权所有(C)2015 John Wiley&Sons，Ltd.
Desertification is among the most severe global environmental and the socio-economic problems in the world. This paper is a first attempt to link scientific research to national policymaking on desertification in China. We aim to trace scientific research findings in the national policies and strategies of desertification prevention in China. One example is the large-scale plantation programme in the dust source region threatening Beijing and Tianjin since 1998. It has been suggested that the recent increased forest cover due to plantations in North China has helped reduce dust storm emissions and contributed to mitigating dust storm weather in Beijing and Tianjin. Reforestation/afforestation policy remains in the Chinese national environmental strategies for the new national forestation programme (2011-2020). Overgrazing during recent decades has been blamed for land degradation and desertification in Northwest China by many scholars. Small field experiments prove that vegetation in desertified/degraded land could recover if isolated from human activities. Since 1998, natural recovery has become one powerful national force to prevent land desertification and recover natural vegetation. One example is selected at Cele County, Xinjiang Uygur Autonomous Region to showcase how vegetation could thrive at large scale in natural arid and semi-arid climate if isolated from human intervention. The plantation project has pushed the stakeholders to better understand their negative impact on the environment, especially the overgrazing behaviour. After that, the household income and living level have also been significantly enhanced; however, it is not clear whether the project induced labour migration.
