The effect of ecological restoration on soil organic matter in semi-arid land: A chronosequence study in the Kubuqi Desert

Dr Liwei Chai1

1Peking University, Beijing, China

My name is Chai Liwei, and I am right now a PhD candidate of Environmental Sciences in Peking University. Our research mainly focused on soil organic matter dynamic during artificial ecological restoration and its potential biological mechanism in semi-arid land. Our studies tried to elucidate the decomposition change of soil organic matter, especially in the view of organic matter with different bio-availability, during ecological restoration project. To do so, we are using traditional organic matter analytical method in combine with emerging spectrographic technique (Excitation-emission matrix) and microorganism analytical technique (soil enzyme assay and high-throughput sequencing). We hope our study could help us understand the biological induced organic matter accumulation process during anthropogenic ecological restoration and therefore provide direction in the future ecological movement.
