The loess hilly region is a typical ecologically fragile and sensitive area. It is of great significance when measuring the balance between supply and demand of ecosystem services and clarify the relationship between supply and demand of ecosystem services for scientific ecological restoration zoning and realizing regional ecological security and social and economic sustainable development. We take Yuzhong County in the loess hilly region of Longzhong, China as an example; by constructing the matching and coordinating relationship between ecosystem service supply and demand and following the idea of “problem diagnosis—strategic orientation—key optimization”, this paper delimits the ecological restoration zones and proposes corresponding governance strategies. The results show that: (1) The supply and demand of ecosystem services were mainly at a low and medium level, with significant spatial heterogeneity. Overall, the spatial pattern of ecosystem services showed high supply and low demand in the southwest mountainous areas and showed low supply and high demand in the urban gully areas of Yuzhong. (2) There were four types of spatial matching of ecosystem service supply and demand: HH type, LH type, LL type, and HL type. The local spatial autocorrelation of supply and demand was dominated by high-low or low-high spatial misadjustment. The average degree of coordination between supply and demand of ecosystem services was 0.629, indicating that supply and demand were basically coordinated. (3) The ecological restoration zones in Yuzhong County can be divided into six categories: the ecological core protection area, ecological potential restoration area, key ecological restoration area, soil and water conservation restoration area, ecological agriculture development area, and ecological innovation promotion area. The results of this study can provide ideas for the refined management and targeted restoration practice of regional ecosystem services. It provides a strong guarantee for ecosystem management and decision-making in the loess hilly region.

Exploring the spatial differentiation and driving mechanism of labor flow can effectively promote the flow of urban and rural factors and provide a basis for rural revitalization. This paper used the theory of push and pull for reference to explain the role of push and pull in the process of labor migration. On this basis, the paper analyzed the social space characteristics of labor in Longxi County and explored the impact mechanism of local quality on labor migration. It was found that the characteristics of labor migration in Longxi County had a distance attenuation effect and gravitational effect, and the spatial agglomeration of labor attributes was obvious. This was closely related to local quality differences. The labor migration was conducted under the comprehensive effect of the local quality of the source and destination. The local quality of the source was the basic power of the labor migration. The difference in the local quality between destinations was the main reason for the spatial difference in the number and attributes of the labor force. Specifically, the degree of interconnection and cooperation affected the labor migration distance, and the relatively poor employment income-generating capacity and regional livability in the western underdeveloped regions affected the labor quantity. The young and middle-aged labor force was greatly affected by the regional environment.

Global food production is facing increasing uncertainties under climate change and the coronavirus pandemic, provoking challenges and severe concerns to national food security. The role of global agricultural trade in bridging the imbalance between food supply and demand has come to the fore. However, the impact of multifaceted and dynamic factors, such as trade policies, national relations, and epidemics, on the stability of the agricultural trade network (ATN) needs to be better addressed. Quantitatively, this study estimated grouping characteristics and network stability by analyzing the changing global ATN from 1986 to 2018. We found that the evolution of global agricultural trade communities has gone through four stages: the dominance of the US–Asian community, the rise of the European–African community, the formation of tri-pillar communities, and the development of a multipolar community with a more complex structure. Despite witnessing a progressive increase in the nodal stability of the global ATN during the decades, particular gaps can still be found in stability across countries. Specifically, the European community achieved stability of 0.49 and its trade relations were effectively secured. Meanwhile, the remaining leading communities’ stability shows a stable and upward trend, albeit with more significant challenges in trade relations among some of them. Therefore, how to guarantee the stability of trade relations and strengthen the global ATN to resist external shocks has become an essential question to safeguard global food security.

The discourse regarding place attachment (PA) has grown even more divergent, and an array of scholars and practitioners apply place attachment concepts in their work, drawing out associations between PA and environment-related behavior and revealing how an understanding of people’s attachment to place can influence research, policy, and design practice. In this paper, we use bibliometrics and CiteSpace software to quantify and visualize 528 publications of place attachment and environment-related behavior research (PAEBR) in the core collection database of Web of Science (WoS) from 1 January 2004 to 1 November 2022 and trace the main overview of the research from the number of published papers. First, we present the number of papers published, research discipline distribution, the core authors of articles, the fundamental condition of countries and research organizations, and the major journals of articles involved in PAEBR through bibliometrics. Second, we identify trending research topics in PAEBR using keyword co-occurrence analysis. The results show that the four research trending topics involved climate change, pro-environmental behavior, and environmental threat. All of these provide readers with a preliminary understanding of PAEBR, indicating that cooperation and analysis involving multiple disciplines, specialties, and perspectives will become the dominant trend in this field.
