Abstract:

In order to achieve harmonious ecological and economic development in urban agglomerations, it is important to explore the trade-offs between environmental protection and economic development, and use this knowledge to optimize land use allocation. This study aimed to simulate land use changes in the Beijing-Tianjin-Hebei urban agglomeration with different goals and under different scenarios in 2025 to identify the optimal land use allocation strategies based on the trade-offs between ecological and economic benefits. In order to meet the land use demands for environment-friendly development in the Beijing-Tianjin-Hebei urban agglomeration, we developed two optimization goals—ecosystem services value maximization and economic value maximization, and four land use scenarios—environmental protection, balanced development, food security, and economic development focus. A CLUE-S model was built to simulate and predict the optimal land use allocation strategy. The results show that the optimal land use allocations with the ecosystem services maximization goal were very different comparing to that with the economic value maximization goal. The ecosystem services value is estimated to be approximately 1442.36 billion Yuan with the ecosystem services maximization goal and under the environmental protection scenarios, more than that with the economic value maximization goal and under the same scenario. Spatially, the increase of ecologically beneficial land-use types, including forest land and grassland, is more often seen in the Bashang Plateau, Yanshan Mountains, and Taihang Mountains. The increase of water areas often occurs in coastal regions in the east. There are significant trade-offs between ecosystem services value maximization and economic value maximization. The results of this trade-off analysis can provide a basis for future ecological projects in the Beijing-Tianjin-Hebei urban agglomeration.
