| Abstract: | Through field surveys and sampling,combined with laboratory analysis,the characteristics of soil organic carbon content about local four kinds of lands(orchard,woodland,grassland,slope farmland) were studied.The experiments indicated that the mean of organic carbon of all soil sampling area(SOC)were 13.13g·kg-1.Among them,the mean of slope farmland organic carbon were 12.93g·kg-1,compared with the slope farmland,orchard soil organic carbon mean(12.97g·kg-1) was slightly higher than it,that of grassland and forest land were higher than the slope farmland by 3.4% and1.16%.The mean of soil organic carbon among orchard,woodland,grassland,slope farmland was no significant difference.In various forms of land uses the soil organic carbon and water content had a strong linear correlation.According to this experimental data and field research,the ability of carbon fixation in woodland and grassland soil carbon was stronger than that in orchard and slope farmland.This result provided some scientific basis for local soil erosion. |
