Yan Xiaoyuan

Yan Xiaoyuan serves as a Research Fellow and doctoral supervisor at the Nanjing Institute of Soil Science, Chinese Academy of Sciences, specializing in soil biogeochemical processes and agricultural environmental systems. His work bridges Chinese and international research initiatives with significant funding from national and global agencies.

His academic foundation includes:

• Bachelor of Agronomy, Hunan Agricultural University (1988-1992)
• Master's Degree, Nanjing Institute of Soil Science, CAS (1992-1995)
• Doctoral Degree, Nanjing Institute of Soil Science, CAS (1995-1998)

Dr. Yan's research centers on carbon-nitrogen cycle dynamics in agricultural watersheds, with emphasis on greenhouse gas emissions (CH₄, N₂O) and soil quality evolution. His methodologies integrate field studies across China-Japan comparative frameworks and develop rapid assessment protocols for farmland degradation. Current projects address nitrogen's impact on water quality, historical soil quality changes since China's Second Soil Census, and agricultural emission inventory refinement.

As principal investigator, he directs multiple high-impact grants including a National Natural Science Foundation of China international cooperation project, a CAS Innovation Group Project on soil interface processes, and Japanese Ministry of Environment funding for emission reduction evaluation. His work demonstrates strong interdisciplinary collaboration across agricultural ecology, environmental chemistry, and climate change mitigation frameworks.
