李勇 男，研究员，博士生导师。
1992 — 1998年在中国科学院南京土壤研究所工作，1998—2002年在澳大利亚墨尔本大学留学，获澳大利亚墨尔本大学哲学博士学位。2002 —2009年在澳大利亚墨尔本大学土地和粮食资源学院从事研究工作。2009年7月至今在中国科学院亚热带农业生态研究所工作，并入选长沙市“313计划“。研究方向为亚热带地区的农田生态系统水-碳-氮-磷物质循环及氮-磷污染防治、流域环境模型、亚热带生态系统温室气体排放、区域气候变化对农业的影响及其适应措施的研究、地球表层物质生源要素比率与农业生产力的关系等。
在澳大利亚墨尔本大学留学和科研的十年期间，主要从事农业生态系统计算机数值模拟研究，开发了Water and Nutrients Management Model (WNMM), 用于详细模拟农业生态系统中水, C-N-P 物质循环(包括土壤温室气体的排放), 作物和牧草生长及农业管理措施, 精确指导农业生产活动。该模型已经在中国, 澳大利亚，韩国, 英国，意大利和美国的不同农业生态系统中得到广泛的应用，模拟和预测农田(包括小麦、玉米、牧草、水稻和甘蔗)中主要温室气体(CO2, NO和N2O)的排放及减排措施的筛选，研究成果均在国际权威学术期刊发表。在综合分析全球土壤N2O排放模拟模型的基础上，建立独特的结构简单且灵敏度高的WNMM温室气体排放模块。基于WNMM, 开发出具有自主知识产权的区域(基于GIS)农业生产决策支持系统, 帮助农业生产人员进行最优化的农业生产措施管理, 包括施肥和灌溉。指导博士和硕士研究生共6名。共发表科学论文50余篇，其中SCI收录30多篇，并被多种国际SCI期刊外引100余次。。
