Abstract:: Through the combination of standard survey and biomass measurement, the carbon storage, carbon increment and distribution of Pinus yunnanensis forest ecosystems of contour reverse-slope terrace after 8 years were analyzed in the middle of Yunnan Province. The results showed that the biomass of tree layer, litter layer, shrub layer and herb layer of Pinus yunnanensis forest of contour reverse-slope terrace was 9.07%, 9.29%, 8.17% and 13.24% higher than that of the control, respectively. The biomass under contour reverse-slope terrace of different layer decreased in the order:tree layer (75.65 t/hm²) > litter layer (23.69 t/hm²) > shrub layer (4.68 t/hm²) > herb layer (1.80 t/hm²); in the contour reverse-slope terrace, the carbon storage was 27.10% higher than that of the control; the carbon storage of each layer presented in the order:soil layer (132.09 t/hm²) > tree layer (35.32 t/hm²) > litter layer (5.94 t/hm²) > shrub layer (2.11 t/hm²) > herb layer (0.74 t/hm²), which accounted for 72.12%, 22.26%, 3.86%, 1.31% and 0.45% of the total carbon storage, respectively; the carbon increase of contour reverse-slope terrace was significantly higher than that of the control (29.68%), and the carbon increases of the tree layer, shrub layer, herb layer, litter layer and soil layer were 31.76%, 28.21%, 27.17%, 15.54% and 34.92% higher than that of the control, respectively. In summary, the contour reverse-slope terrace can effectively promote plant growth and increase the accumulation of carbon storage in vegetation and soil layer. Therefore, it is possible to apply contour reverse-slope terrace measures to accelerate local carbon storage during artificial afforestation. If that’s the way, the recovery rate of the carbon pool and ecological environment can be accelerated, and the productivity of forest ecosystems can be increased.
