Abstract:

Haihe River basin (HRB) is a major farm region with extensive shelterbelt in China. It was important to undertake an assessment of the present and potential carbon sequestration of shelterbelt in agricultural areas of HRB. The author had established a comprehensive method to evaluate the biomass and carbon storage of shelterbelt, including high resolution RS data (about 1 m), land use/cover data and field survey data of the tree biomass of 5 typical shelterbelt spots. The results showed that the present total carbon storage of shelterbelt in agricultural areas of HRB was (0.97-1.55)×106 t, and the annual carbon fixation was (0.13-0.21)×106 t/a, respectively. While the shelterbelt had planted over the entire reasonable field path, the potential maximum carbon storage would increase to (4.71-7.53)×106 t, and the annual carbon fixation was (0.63-1.01)×106 t/a, respectively. There were huge volumes and potential of the carbon storage of shelterbelt in agricultural areas of HRB. It should enhance the regional ecosystem carbon storage and give a new pathway of carbon sequestration in the agricultural region to strengthen the shelterbelt management and construction level.
