从国家自然科学基金资助项目分析应对土壤镉污染的研究发展方向

摘要

为探讨应对日益严重的土壤镉(Cadmium, Cd)污染的研究发展方向，分析了2000～2013年国家自然科学基金批准资助的155个与之相关的项目。结果表明：这些项目主要由面上项目和青年科学基金项目资助；近年来，相关项目的资助力度正逐步加大；所有项目可分为9大研究方向，其中以植物吸收转运积累镉的机理和相关基因研究所占总项目数的比例最大。对未来的研究方向也作了展望。%In order to probe into the research fields to reply the increasingly serious soil cadmium (Cd) contamination, 155 related projects supported by National Natural Science Foundation of China (NSFC) in 2000-2013 were studied. The results indicated: the projects were mainly supported by general program and youth science fund project. In recent years, the support intensity of related projects was gradually increasing. All the projects can be classified into 9 research fields, and studies about the mechanism and related genes of cadmium absorption, transportation and accumulation in plants account for a largest fraction in all the projects. Furthermore, prospects for further study were summarized.
