为提高地球环境变化条件下预测土壤侵蚀的能力，国际地球──生物圈研究项目（IGBP）中的地球变化与陆地生态核心项目已经建立了一个国际研究网──GCTE。该网络紧紧围绕长期的土壤侵蚀监测、土壤侵蚀的试验处理、土壤侵蚀的3种预测模型等3个密切相关的主题开展工作。GCTE有3个分支机构。它的运行依赖于多国协作。GCTE能对现有模型敏感性和灵活性进行测试，并且可以在数据缺乏的情况下进行实验。但探讨因地表裸露、土壤结皮和侵蚀造成的反照率的变化，使在一个区域范围内与总循环模型相联系，还必须进行综合研究。
In order to improve the ability of predicting soil erosion under the changing conditions of the Earth’s environment, an international research network, CGTE, has been set up in the IGBP Core Earth Change and Terrestrial Ecology Project. The network works closely on three closely related topics: long-term soil erosion monitoring, soil erosion testing and three soil erosion models. GCTE has three branches. Its operation relies on multinational collaboration. GCTE tests for the sensitivity and flexibility of existing models and allows experiments to be conducted in the absence of data. However, the change of albedo due to surface nuisance, soil crust and erosion should be discussed in order to link with the general circulation model in a region and must be studied comprehensively.
