    Abstract
  • In order to explore the effects of rocky desertification control on the changes of CO2 and CH4 in soil and the effect of carbon sink, the CO2 and CH4 concentrations in the rocky desertification control demonstration area of Nanchuan,Chongqing were observed by gas chromatography, The effects of rocky desertification control on the changes of CO2 and CH4 in soil were analyzed combined with soil temperature, soil moisture content, soil bulk density and soil organic carbon in different soil layers in experimental area (the rock desertification control area) and comparison areas (grassland without rocky desertification control), the effect of rocky desertification control on karst sink effect was studied (experimental area) and the amount of karst carbon sink was also estimated using the dissolution data. The results show that，(1) The changes of CO2 and CH4 in soil are different in terms of time and space. The CO2 concentration increased firstly and then decreased with soil depth, and the variation range was 393-7，400 mg·L-1 ,while the CH4 concentration decreased firstly and then increased with soil depth, the variation range was 1.13 -3.42 mg·L-1. (2)The mean CO2 concentration in the experimental area was 2，131 mg·L-1 , and the mean value of CH4 was 1.94 mg·L-1,whereas the mean CO2 concentration in the comparison area was 2，338 mg·L-1 and the mean value of CH4 was 2.10 mg·L-1. (3)Soil temperature and soil organic carbon had a significantly positive correlation with CO2 , but negatively correlated with CH4 in soil, indicating that soil temperature and soil organic carbon are the main factors affecting the concentration of CO2 and CH4 in soil. (4)The relationship between soil temperature and CO2 was positive and the correlation was weakened with the increase of rocky desertification control, indicating that the impact of soil temperature on soil CO2 concentration was weakened after rocky desertification control. (5)The dissolution rate of karst test strip in the experimental area is larger than that in the comparison zone, and after the the treatment of rocky desertification, the carbon sink generated by karst processes can be increased by 0.66-9.42 t·km-2·a-1,indicating that the rocky desertification control improves the carbon sink in the karst area.
