The Study of Ecological Service Value of Farmland Ecosystem in the Beijing-Tianjin-Hebei Region

The coordinated development of Beijing-Tianjin-Hebei Province has become major national strategy of the CPC central committee and the state council under the new historical conditions. The farmland of Hebei Province has made great contribution to food supply for Beijing and Tianjin in a long time. Hebei Province has played a more important role in the ecological function especially. The geographic grid method was adopted in this study to account the ecosystem service value of farmland in Beijing-Tianjin-Hebei region. The result showed that total farmland ecosystem service value in 2015 was 110.3 x 109 yuan and the proportion of ecosystem service value in Hebei Province was the highest which reached up to 92.56%. The results of the evaluation of ecological services could provide the basis for determining the ecological compensation standards for farmland in Beijing-Tianjin-Hebei region.
