5. CONCLUSION
We conclude that it may be valuable to pay attention to LUCCs as a
strategy to relieve climate pressure in some cases, but its impact shows
great variation (i.e., showing positive and negative SOC / TN gains).
Besides the LUCCs (reforestation and land restoration), the future
research should include more extensive depth sampling and appropriate
accounting methods. In addition, the results of meta-analysis indicate
that there is a high degree of variation in SOC / TN storage, and it may
be unwise to estimate the benefits / losses of SOC / TN storage from a
specific soil depth. To quantify the storage of SOC and TN in response
to LUCCs, the increased depths of the soil profile Finally, we suggest
that environmental factors (i.e., geography, climate, soil properties
and time factors) should be considered as potential predictors to assess
of SOC accumulation under the concession station and land restoration in
Karst A comprehensive and accurate understanding of SOC / TN storage
response to LUCCs is a strong support for climate change mitigation and
food security strategies.
