Book excerpt: The evolution of land space demonstrates the shift of land use types from natural and semi-natural land (e.g., forest land and cropland) to built-up land, altering ecosystem cycling patterns and leading to degradation of ecosystem services in terms of regulation, provisioning and support. At the same time, production and living space crowding out ecological space brings high potential threats, such as soil erosion, forest productivity decline and habitat fragmentation. Accordingly, in response to the problems of imbalanced territorial space development, inefficient resource utilization and ecological environment degradation, how to improve the diversity, stability and sustainability of ecosystems is an urgent issue to promote modernization and green development in the new era of territorial space evolution.
