[Abstract]

　The activities to combat desertification in China have been conducted since 1950s. After several decades' efforts, extensive projects have been carried out and huge amount of data have been accumulated, which are extremely valuable for control the expansion of desertification over the world. However, because the evaluations of these projects and technologies are not fully done and relationships among them are not fully analyzed, the application of these technologies is very limited. Therefore, this project focuses on data collection, literature review, and analysis. Based on it, the technologies which are effective to control desertification have been analyzed and evaluated. These technologies include straw-checkerboard technology to fix sand dune, vegetation establishment technology to rehabilitate the environment, sowing seeds by airplane, and desertification-monitoring technology. The possible application condition and the effect for control desertification of each of them are analyzed and discussed.
