The basic premise of regional ecological construction would be to scientifically and effectively grasp the characteristics of land use change and its impact on landscape ecological risk. The research objects of this paper are the typical areas of the Yellow River Basin in China and “process-change-drive” as the logical main line. Moreover, this paper is based on multi-period land use remote sensing data from 2000 to 2020, the regional land use change process and influencing factors are identified, the temporal and spatial evolution and response process of landscape ecological risk are discussed, and the land use zoning control strategy to reduce ecological risk is put forward. The results indicated: (1) The scale and structure of land use show the characteristics of “many-to-one” and “one-to-many”; (2) the process of land use change is affected by the alternation of multiple factors. The natural environment and socio-economic factors dominate in the early stage and the location and policy factors have a significant impact in the later stage; (3) the overall landscape ecological risk level and conversion rate show a trend of “high in the southeast, low in the northwest”, shift from low to high and landscape ecological risks gradually increase; and (4) in order to improve the regional ecological safety and according to the characteristics of landscape ecological risk and spatial heterogeneity, we should adopt the management and control zoning method and set different levels of control intensity (from key intensity to strict intensity to general intensity), and develop differentiated land use control strategies.

With the large-scale development of urbanization in the world, phenomena such as the unbalanced allocation of various elements of the rural regional system, as well as the decline of the economic and social structure and functions in the process of urban and rural economic and social transformation and development in China, have endangered the healthy development of rural areas. The “hollowing” of rural areas is becoming more and more intense, and the governance of hollow villages has become a key link to stimulating the vitality of rural development and realizing the coordinated development of urban and rural areas. Taking a typical hollow village in Fangsi Town, Yucheng City, Shandong Province, China as an example, through the recognition method of hollow villages mode, the study adopted the in-depth interviews and questionnaires to obtain governance of hollow villages. Moreover, this study uses the actor–network theory to discuss the governance model mechanism and policy response of hollow villages, extract the applicable conditions of different hollow village governance modes, and provide the promotion of the hollow village governance mechanism. Our findings show that: (1) the governance modes of hollow villages are diverse. Under certain geographical conditions, the governance of hollow villages shows the relocation and merger–urban–rural integration mode, village integration-scale operation mode, village intensive-idle land revitalization mode, and original site optimization–sightseeing tourism development mode, along with other types. In the process of promotion and use, appropriate adjustments should be made in combination with differences and changes in system conditions, and the accurate governance of villages should be carried out. (2) The governance process of hollow villages is dynamic. The governance of hollow villages represents a heterogeneous network of actors led by key actors, which mainly realizes changes in the rural material space. With the change of development goals of the hollow village, the network of actors has been readjusted around the new OPP, and the role of the actors has changed, correspondingly showing a transition from the governance of the hollow village to the optimized development, thus further realizing the transformation of the hollow village.

Accurately identifying the matching relationships between territorial space evolution and the resources and environment carrying capacity will directly guide the sustainable use of territorial space. Based on the evaluation of the territorial space dynamics of the lower Yellow River, this paper evaluates the suitability of territorial space development by focusing on ecological protection, agricultural development, and urban construction. Specifically, the resources and environment carrying capacity is estimated by identifying and mediating potential conflicts in the development of territorial space. The matching relationship between the evolution of territorial space and the resources and environment carrying capacity is identified using the matching degree model. The results demonstrated that: (1) Between 2000 and 2020, the agricultural space of the lower Yellow River was relatively stable, while the ecological space was generally shrinking, and the urban space continued to increase; (2) The characteristics of suitability for the agricultural development and urban construction of the lower Yellow River are characterized by landform and land-sea differentiation. The carrying scale of resources and the environment is based on agricultural space and is increasing yearly, followed by ecological space, which is gradually decreasing, and urban space, which first increased and then decreased; (3) Between 2000 and 2020, the matching index of the ecological and agricultural space evolution and the resource and environmental carrying capacity in the lower Yellow River exhibited a downward trend, while the regional difference increased. Furthermore, the matching index of urban space and the resources and environment carrying capacity indicated an upward trend, while the regional difference decreased.
