个人简介

刘学炎,教授,博导

1982年生,贵州金沙县人。2003年贵州师大地理系本科毕业,2008年在中科院地化所博士毕业,2009-2014年于东京农工大学从事博士后研究。曾获国家青千(2015)、国家自然科学优秀青年基金项目(2015)、天津市首批杰出青年基金项目(2017)和国家自然科学杰出青年基金项目(2021),主持国家自然科学重点基金、国家重点研发计划‘大气污染与防治’和‘全球变化与应对’课题、IAEA降水氮同位素研究课题等。氮是地球生命活动必需营养元素之一,但近百年来人类活动导致大气活性氮排放快速持续增加,生成二次颗粒物,影响空气质量,同时增加陆生系统的大气氮输入,诱发植物多样性和固碳能力变化、土壤酸化、水体氮富集等问题。研究主要致力于氮同位素地球化学方法创新和应用,聚焦地表氮素来源和地球化学过程机制研究,为制定活性氮减排策略和评估氮富集的效应提供科学依据。
