In order to assess the production costs in major grain producing areas effectively, provide help for the
change of the economic compensation method which linked to agricultural tax area in the past, from the ecological
perspective, interest compensation estimation model for major grain producing areas was constructed based on the
combination of the decline in the virtual water compensation, carbon absorption compensation and soil organic matter
content compensation. Using the data in 2011 in Heilongjiang province, the largest grain producing provinces in China, the
amount of compensation for the unit weight of rice, wheat, corn, soybean through estimate model was obtained, and then the
amount of compensation into the unit area was converted. The data were described briefly, and the further research in the
future was put forward. |
