关于全球性变化的研究著作在90年代大量涌现,其中同时依靠社会科学知识和自然科学知识的著作日益增多。有些人认为这个趋势意味着“沦落到不再确实可靠的地步”。但是,联合国教科文组织主办的开创性研究、诸如“人与生物圈”或“环境问题专门委员会”之类项目,已经开始为这种跨学科研究工作规定科学的方针策略。 Research books on global change sprouted up in the 1990s, with an increasing number of writings relying on both social science and natural sciences. Some people think that this trend means that “reduced to the point where it is no longer reliable.” However, initiatives such as the “Man and the Biosphere” or “Environmental Issues Committee” sponsored by UNESCO have begun to lay down scientific guidelines and strategies for such interdisciplinary research.
