- Abstract:
-
Soil organic carbon (SOC) and nitrogen in forestland are the basis for material recycling in the forest ecosystems, and which are significantly correlated with global climate change. In order to understand the strorage distribution patterns of SOC and nitrogen in Baotianman Nature Reserves, we used soil profile survey method to study the relationship between the SOC, nitrogen storage and C:N ratio with altitude, forest age, and soil types in Baotianman Nature Reserve. The results showed that the amount of forest SOC storage ranged from 14.24 t/hm2 to 137.97 t/hm2, with an average of 82.05 t/hm2 in the 0—30 cm soil layer, the value of soil nitrogen storage ranged from 0.75 t/hm2 to 6.89 t/hm2, with an average of 3.98 t/hm2. SOC and nitrogen storage was significantly lineated with the altitude and forest age (p < 0.05), and positively increased with altitude and forest age increasing. SOC and nitrogen storage showed the differences among the different forest types. SOC and nitrogen storage of the brown soil was significantly greater than that of the yellow brown soil and cinnamon soil (p<0.01). However, C:N ratio was stable with the value of about 20, and did not significantly change with altitude and soil types (p > 0.05). This study revealed the distribution patterns of SOC and nitrogen storage in Baotianman forest region, and was very important for guiding climate change mitigation, forest restoration, and forest ecosystem management and protection in Baotianman Nature Reserve.
