Main work
In the recent years, Prof. Sun Shoujia has worked in the Xiaolangdi Forest National Field Observation and Research Station of the Yellow River and the Xiaolangdi Forest Ecological Station of the National Forestry and Grassland Administration. The interspecific water relationship of agroforestry systems, the degradation and recovery mechanism of shelterbelt forests, and the water use of plantation in low mountain areas have been researched using stable isotope technology. Seven projects, including the National Natural Science Foundation of China, the Beijing Natural Science Foundation, Sub-project of National key research and development program and Sub-project National Nonprofit Institute Research Grant of the Chinese Academy of Forestry, have been funded. More 30 papers (6 SCI papers) as the first and corresponding author have been published. And the Second Prize for Technological Progress of Liangxi has been awarded. One monograph has been published. one patent and one software have been granted.
