Abstract:

Land-use conversion has a significant impact on greenhouse gas emissions. The experimental fields are located at the Qianyanzhou Ecological Research Station (26°44′48″N,115°04′13″E), operated by Institute of Geographic Sciences and Natural Resources Research of Chinese Academy of Sciences. We converted a portion of the area under rice which had been continuously cultivated with rice for approximately 10 years to vegetable land. The treatments were in 8 different ways, including rice with (R-F) and without fertilization (R-NF) and vegetable with (V-F) and without fertilization (V-NF). We also set up a sub-treatment for removing vegetation in each plot (-no plant). They are: rice with (R-F-no plant) and without fertilization (R-NF-no plant) and vegetable with (V-F-no plant) and without fertilization (V-NF-no plant). The static opaque chambers and gas chromatographs (GCs) were used to determine the fluxes of methane (CH4), nitrous oxide (N2O) and carbon dioxide (CO2) in situ for two years. We studied the greenhouse gas fluxes changes at the beginning period of the land-use conversion from double rice cropping to upland vegetables. Besides, the effect of fertilization and the crops on the fluxes of CH4, N2O and CO2 were investigated. The data set is stored in .xls format, and the compressed data volume is 286 KB. This dataset is consisted of 8 tables in one data file: Table 1: Management information of the paddy and vegetable fields. Table 2: CH4 fluxes of each treatment from July 2012 to July 2014. Table 3: N2O fluxes of each treatment from July 2012 to July 2014. Table 4: CO2 fluxes of each treatment from July 2012 to July 2014. Table 5: Soil ammonium and nitrate nitrogen content of 0-20 cm of paddy and vegetable fields. Table 6: Soil pH of 0-10, 10-20 cm of paddy and vegetable fields; Table 7: Daily air temperature and precipitation of the experimental area. Table 8: The water depth of paddy fields. The dataset indicates that land-use conversion from rice to vegetables significantly reduced CH4 fluxes and significantly increased N2O fluxes. The conversion had inconsistent effects on CO2 fluxes across seasons. The total global warming impact of the three greenhouse gases was significantly increased after the land-use conversion from paddy to vegetables. Fertilization had no significant effect on CH4 fluxes, while significantly increased N2O and CO2 fluxes and had an interaction with land use types. The changes of CH4, N2O and CO2 fluxes with the land-use conversion from paddy to vegetable fields were caused by the changes of soil properties and the changes of crop types together. The analysis papers of this dataset were published in PLoS ONE 2016 No. 11 and Chinese Journal of Applied Ecology 2015 Vol. 26 No. 1.
