Abstract:

Based on Meta-analysis, the ecosystem service value regression models for cultivated land, forest land, pasture, garden land, waters and unused land were established respectively. In addition to time and value method, the geographical division and socio-economic factors (including population density and GDP per capita) were also incorporated into the models. The performance of model indicates that these factors play a significant role in explaining ecosystem service value change. Using value transfer approach, the authors valued ecosystem service of land use types in Beijing, Tianjin, and 11 cities in Hebei Province. The results show that land use types ranked by ecosystem service value are waters, forest land, pasture, garden land, cultivated land and unused land. The ecosystem service values per unit area of cultivated land, forest land, pasture, garden land and water area in Beijing and Tianjin are more than other areas. The research results on the one hand can enrich the methodology and technology of ecosystem service valuation, on the other hand provide scientific support for land use sustainable management in study area.
