China. This project focuses on the Beijing-Tianjin-Hebei (BTH) urban megaregion, one of the largest urban megaregions in China. The BTH urban megaregion has been experiencing rapid urban expansion since the late 1970s and the early 1980s, which resulted in a series of ecological and environmental problems, such as air pollution, ecosystem degradation, and loss of wetlands. How to balance the development of different cities in this region, and coordinate its relationship with environmental protection and ecological restoration has increasingly become a priority issue in this region. The overall objective of this project is to develop new technologies for ecological restoration and establishing a eco-security pattern. Specifically, we aim to 1) understand the mechanism of the current eco-security pattern development and its key driving factors; 2) to develop key technologies for ecological restoration of degraded wildlife habitats, damaged key ecological function areas, for ecological monitoring and management, and for ecological risk prediction and early-warning; and 3) to establish a decision-making support system, and a forecasting and early-warning platform. Results from this project will provide insights on understanding the patterns of eco-security in the BTH urban megaregion, and also provide technologies to support local practices of ecological restoration, and tools for regional decision-making to balance economic development and environmental protection in the purpose of enhancing eco-security. In addition, such practices and scientific understanding will also benefit the scientific community and decision makers in other megaregions. 参考文献 相似文献 引证文献
