英文摘要	Desertification in Kazakhstan affects the country's environment, agriculture and animal husbandry. It is critical to quickly and accurately identify the locations of desertification land and grasp the main causes of desertification in different states in Kazakhstan. This paper builds a new technical framework for desertification identification. Through a comprehensive analysis of desertification sensitivity, long-term trends and stability of net primary productivity (NPP), the authors determined the spatial distribution of land desertification in Kazakhstan and further analyzed the possible driving factors of desertification. The results showed that (1) approximately 76.1% of Kazakhstan land is considered desertification sensitive areas with moderate and higher sensitivity; (2) the area of desertification land in Kazakhstan is approximately 1.04 x 10(5) km(2), accounting for 3.8% of the total land area, which is mainly distributed across seven states in western, northwestern and southwestern Kazakhstan; and (3) in the four main desertification states (West Kazakhstan, Aktobe, Mangystau and Atyrau), the climate warming and drying trends are significant. Large-scale and intensive human activities in agriculture and animal husbandry in the two main desertification regions in northern Kazakhstan have promoted land desertification to some extent. Targeted agricultural and industrial regulatory actions should be taken to prevent and control land desertification. The desertification mapping technical framework established in this paper can be used in other parts of the world. The conclusions about the driving factors have reference value for the government authorities of the states of Kazakhstan.
