ESTIMATION AND SPATIAL VISUALIZATION OF ECOSYSTEM SERVICES VALUE IN BEIJING, TIANJIN AND HEBEI PROVINCES

摘要

The main purpose of this paper was to estimate and map the ecosystem services value of Beijing, Tianjin and Hebei region. Considering regional spatial heterogeneity, the stage of social development, resource scarcity, and differences in the biomass of ecosystem, the estimated results of non-construction land were more practical. Based on the ecosystem services value of the region, we carved out individual indicator divisions with the ecosystem services value per unit area (ESVU), ecosystem services value per capita (ESVP) and ecosystem services value/GDP (ESVG) respectively; and then analysed comprehensive regionalization with the above indicators to explore the spatial and temporal heterogeneity of ecosystem services values in the area. The results showed that the ecosystem services value in region increased from 1990 to 2000, and then decreased in 2010. The ecosystem services value of the region were dominated by regulating services value(RSV) and supporting services value(SSV), the sum of the two accounts for 80% of the whole area. The mapping of individual indicators and comprehensive regionalization showed a significant step-structure, and the ecological service value of the region had certain temporal and spatial heterogeneity. The determined carrying capacity of the ecosystem services value was not optimistic for population growth and economic sustainable development in the area. In view of the above, the paper put forward measures to guide regional sustainable development.
