Distribution of Soil Organic Carbon and the Influencing Factors in An Oasis Farmland Area
摘要
Abstract
The soil organic carbon(SOC)of a typical oasis farmland in middle part of Manasi county of Xinjiang was used as the research ob-ject. Using remote sensing and lab analysis techniques, influences of soil texture, terrain, land uses, and crop types on SOC content of farm-land were studied. Results showed that the SOC distribution in farmland of Manasi was mainly determined by comprehensive natural environ-mental factors. The SOC content decreased along with the increasing soil depth. For soil textures, the SOC content from high to low was clay loam>powder loam>silty loam. Slope direction had significantly positive correlations with SOC contents at 0~30 cm and 30~60 cm, while alti-tude and SOC content at 60~100 cm were significantly positive correlation. The SOC content of orchard was the highest, and the uncultivated land was the lowest under different land-use patterns. For different crop planting systems, the order of SOC content was corn field>wine grapes field>cotton field, and the difference was significant.关键词
