RESUMO
Landscape services are an important basis for maintaining regional ecological security patterns, environmental health, and sustainable socio-economic development. As an important link between regional ecosystems and socio-economic development, micro-agents' production and life as well as their cognition and perception of landscape services notably impact the maintenance of multi-functional landscape development. This paper examines 9 rural communities in different areas and different development types in the headwater area of the Qiantang River in China, China's national key ecological functional area, in a typical case study. Based on farmer interviews and household surveys, this paper explores the changes of micro-agents' diversification perception of landscape services from 2010 to 2020. A multiple linear regression method is used to construct an index model of agents' perception of diversification of landscape services and to analyze the driving factors influencing changes. The results showed that (1) from 2010 to 2020, the micro-agent perception index of the diversity of farmland, forest, garden, and grassland landscape services increased by 0.46, 0.43, 0.67, and 0.51, respectively. Among them, the micro-agents' diversified perception of forest, farmland, garden, and grassland landscape services decreased in sequence. (2) From 2010 to 2020, in regard to the importance and vulnerability of landscape services, the difference between the perception levels of farmland landscape support services and grassland landscape regulation services in the agricultural production core area was the largest. In management and rationality perception of landscape services, the difference in the perception between grassland landscape service ecological and economic development areas was the largest. (3) Individual and family characteristics are important factors affecting the diversification perception of landscape services, while the natural environment and resource endowment impose negligible influences. Environmental policies only affect the diversification of grassland perception. The research results can provide a reference for maintaining regional landscape services, improving the well-being of micro-agents, and promoting the enhancement in ecological services and regional collaborative development.

Cultural ecosystem services (CESs) are an important part of ecosystem services (ESs). Correctly understanding the supply and demand relationship of CES is the premise of ES sustainable management and helps to improve human well-being. However, the evaluation and mapping of CES supply and demand represents a significant gap in ES research. Using the Shigou Township of Mizhi County in China as an example, in this study, we evaluated CES supply and demand at the village scale. We first considered three aspects of supply potential, accessibility and quality to construct an indicator system of six types of CES supply, including aesthetic (Aest), sense of place (SP), social relations (SR), cultural heritage (Cult), education (Edu) and recreation (Recr) and obtained demand data through a questionnaire. Then, we identified the imbalance in the supply and demand of CES by Z-score standardization based on the quantification of the CES supply and demand. Secondly, bivariate spatial autocorrelation analysis was used to identify tradeoffs/synergies on the CES supply side, and chi-square tests were used to identify CES demand differences between stakeholder groups. The results indicated that the supply-demand patterns of CES presented evident spatial differences. The low-supply-high-demand patterns of Aest, SR and Recr accounted for the largest proportions, with values of 33.33%, 33.33% and 30.95%, respectively. The low-supply-low-demand patterns of SP and Cult accounted for the largest proportions, with values of 30.95% and 38.10%, respectively. The low-supply-low-demand pattern of Edu accounted for the smallest proportion (21.43%) and was mainly located in the south of Shigou Township. The southwest, northeast and central areas of Shigou Township were the key regions of tradeoffs/synergies of CES supply. There were significant differences in CES demand for SR, Cult and Edu among stakeholder groups. The results could contribute to optimizing regional ecosystem management and provide effective information for improving the imbalance between the supply and demand of CES.

Exploring how people access ecosystem services and revealing the individual capabilities that affect the accessibility of ecosystem services are important for obtaining a clear understanding of the contribution of ecosystem services to human well-being. Previous studies on ecosystem services have incorporated too little empirical research on the accessibility of ecosystem services and on the individual capabilities that affect accessibility. We chose the ecologically fragile and economically underdeveloped Loess Plateau as the research area because local farmers in this area are dependent on ecosystem services. The importance and accessibility of ecosystem services were evaluated on the basis of questionnaire surveys and semistructured interviews. The results showed that crops, meat, and water yield were the most important ecosystem services but were the most difficult to access. In contrast, fruit and soil fertility were easier to access. Furthermore, we determined the individual capabilities of local farmers based on Nussbaum's capabilities list as well as the actual conditions for local farmers and explored the impact of individual capabilities on the accessibility of ecosystem services. The results showed that local ecological knowledge and the ability to socialize were the key individual capabilities determining whether local farmers can access ecosystem services. Compared with farmers who have a formal education, farmers with rich local ecological knowledge can more easily access to crops and erosion control. The ability to socialize reflects the exchanges or donations of ecosystem services among farmers, which increase the accessibility of fodder and organic fertilizer. Physical health, financial capital, and other individual capabilities also have an impact on the accessibility of certain ecosystem services. Therefore, improving these individual capabilities is of great value for improving farmers' well-being. In policy-making and community management, the government needs to consider the development of farmers' individual capabilities in addition to considering poverty alleviation measures.

Exploring and analyzing the common demands and behavioral responses of different stakeholders is important for revealing the mediating mechanisms of ecosystem service (ES) and realizing the management and sustainable supply of ES. This study took Mizhi County, a poverty-stricken area on the Loess Plateau in China, as an example. First, the main stakeholders, common demands, and behavioral responses in the food provision services were identified. Second, the relationship among stakeholders was analyzed. Finally, this study summarized three types of mediating mechanisms of food provision services and analyzed the influence of the different types of mediating mechanisms. The main conclusions are as follows: (1) Five main stakeholders in the study area were identified: government, farmers, enterprises, cooperatives, and middlemen. (2) Increasing farmers' income is the common demand of most stakeholders in the study area, and this common demand has different effects on the behavioral responses of different stakeholders. (3) There are three types of mediating mechanisms in the study area: government + farmers mediating corn and mutton, government + enterprises mediating millet, and government + cooperatives mediating apples. On this basis, the effects of the different types of mediating mechanisms on variations in food yield, and trade-offs and synergies in typical townships, were analyzed.

Social-ecological production landscape resilience (SELPR) is a significant representation of the continuous supply capacity of landscape services. It is a quantitative assessment of the spatial-temporal evolution of SELPR under internal and external disturbances that provides a scientific basis for regional ecological environments and socio-economic development. Taking Mizhi County for the study of the Loess Plateau region, a three-dimensional (social system, ecosystem, and production system) SELPR evaluation framework was constructed. Data integration was performed using the watershed as the evaluation unit. This study quantitatively evaluated the spatial-temporal differentiation of the social-ecological production landscape (SELPs) subsystem's resilience and the total SELPR in the study area and classified the areas from the three-system resilience combination level to achieve regional development trade-offs. The results were as follows: (1) In 2009-2018, the change in the social-ecological production landscapes pattern in Mizhi County showed a significant reduction in agricultural production landscapes, relatively stable social living landscapes, and an increase in ecological landscapes; (2) in 2009-2018, the SELPR increased by 12.38%. The spatial distribution of resilience was significantly different, showing a distribution pattern of high central and low surrounding areas; (3) the county's watershed development zones were divided into five partitions: synergistic promotion areas, ecological restoration areas, social development areas, production optimization areas, and comprehensive remediation areas. The five types of zones have a certain agglomeration effect. In addition, the main obstacle factors affecting the SELPR of each zone are quite different. The key issues and development directions of different types of watersheds are also proposed in this paper.

Including cultural ecosystem services (ES) in the management of an ecosystem can improve the social acceptance and legitimacy of management decisions. In order to adapt to the inherently fragile ecological environment, the Loess Plateau has formed a unique land-use mode and rural cultural landscape, yet the research on the cultural ES in this area is limited. The study of cultural ES from the supply and demand perspective will contribute to realize the sustainable cultural ES supply and meet people's growing demand for a better life. This study conducted a questionnaire survey with 381 people in 42 villages of Shigou Township in the Loess Plateau to explore local residents' demand (perceived importance) of 8 types of cultural ES. The 5-point Likert scale was used to quantify the relative level of residents' demand of cultural ES. Spearman's rank correlation analysis was used to evaluate the correlations between pairs of cultural ES. In addition, this study constructed the indicator system of cultural ES supply from two dimensions of cultural ES supply capacity and accessibility and used a redundancy analysis to explore the linkage between the cultural ES supply and demand. The results showed that residents had a higher demand for esthetics and sense of place, but lower demand for spiritual and religious in Shigou Township. There were significant and positive correlations between different types of cultural ES, and most of them were enjoyed in "bundles." Each type of cultural ES was related to different types of percentage land cover, and geographical distance played an important role in cultural ES supply. Last, we proposed that local residents' perceived importance of cultural ES should be included in decision-making to improve public support for ecosystem management, and managers should simultaneously pay attention to the supply capacity and accessibility of cultural ES to realize the sustainable cultural ES supply.
