“…This result is consistent with those of existing studies on drivers of ecosystem services The speed at which society is developing has quickened the degree to which humans are exploiting the natural environment for resources. As a result, regional natural landscapes undergo a conversion into semi-natural landscapes, including farmland and arti cially created environments (Ma et al, 2018). Simultaneously, the population has been steadily increasing,resulting in an increased demand for both construction lands and food.…”

Ecosystem services value (ESV) can assess the level of basin ecological restoration and provide a basis for ecological management decisionmaking. This study object selects Liaohe River Basin (LHB), a typical basin in Northeast China. The ecosystem service value variation caused by changes in land use cover and the spatial distribution characteristics was evaluated by employing the bene t transfer method, which is based on data sets for land use over 2000-2020. Meanwhile, geographical detector was employed to investigate the impacts and interactions of various factors driving the ESV, and predicted future changes in land and ESV by PLUS model. The results showed the following: 1) LHB land transformations mainly concentrated in the transformation between grassland, farmland and forestland. ESV in LHB decreased and then increased between 2000 and 2020 (1224 billion-928 billion-1238 billion), 2) Ecosystem service value exhibited a strong positive spatial autocorrelation, high ESV was mainly distributed in the eastern and western regions of LHB, and low ESV in the central region.3) The variation in ecosystem service value mainly arises from the human activity intensity index of human factors. 4) In the future, the ecological protection priority scenario can improve the ESV in LHB, and the natural development priority and economic development priority scenario is not conducive to the improvement of ESV. The results show that the ecological restoration effect of the LHB is obvious with the ecosystem service value is signi cantly improved. In the future, attention should be paid to control human activities and strengthen ecological protection in ESV hotspots. structures, processes, and functions of the natural environment and are essential for human survival and progress (Aschonitis et al., 2016. Costanza et al., 1997. Assessing the value of ecosystem services (ESV) is crucial for safeguarding the ecological environment, understanding the role of ecosystems in speci c regions, building sustainable societies, managing environmental economic resources, and making informed decisions on ecological compensation (Daily et al.,2000. Ouyang et al.,1999. Xie et al.,2015. Watershed ecosystems offer us essential products for our survival,as well as important ecosystem services on a large scale like climate regulation,water preservation,carbon dioxide absorption,water and air puri cation,soil and water conservation,and biodiversity (Daily, 1997;Qin et al., 2020).The Liaohe River (LHB) is one of the seven major rivers in China with important industrial and agricultural production base. Home to a population of 34.04 million in the LHB. It is also an important base for steel, machinery, building materials, chemical industry, grain production, and animal husbandry in China. The middle and lower reaches of the LHB are one of the most developed industrial and economic regions in China. Since the 1960s, with the acceleration of economic development, industrialization, and urbanization, numerous human activities have caused interference, es...

“…In particular, the interaction among construction land intensity (X8), distance from road (X9), and other natural factors was always stronger than that with socioeconomic factors. This finding was made because, as the social economy develops, the intensity of human activities has increased, the speed of urban expansion also increases, and some irrational reclamation and construction has occupied green vegetation land, such as farmland, woodland, and grassland, thereby putting great pressure on the ecosystem's stability [41]. Therefore, China should properly control the rate of urbanization and optimize the land use structure.…”

Understanding the spatial differentiation and driving mechanisms of ecosystem service value (ESV) is helpful for the protection and sustainable development of the ecological environment. Despite the fact that various studies on ESV have been conducted in various regions, few studies have discussed the spatial differentiation characteristics of ESV in a long time series at a national scale, and even fewer studies have thoroughly examined the driving mechanism of the spatial differentiation of ESV from the perspective of different regions. On the basis of China’s land use data from 1990 to 2018, this paper used the methods of land use dynamics, the ESV evaluation model, hot spot analysis, the barycenter model, and the geographical detector model to study the temporal and spatial differentiation characteristics of land use and ESV in the study area. Moreover, it analyzes the driving mechanisms of the spatial differentiation of ESV at the national scale and in different regions of China. Our results showed the following: (1) Other land types have increased overall, with the exception of grassland. Obvious differences were observed in the single land use dynamics of each land type, especially the construction land, where farmland was the primary source of construction land. With the passage of time, the dynamic degree of comprehensive land use increased. (2) During the study period, ESV generally showed a decreasing trend, with distinct characteristics in high and low ESV areas. The center of gravity of ESV was constantly in Dingxi County and Pingliang City, Shaanxi Province, and its trajectory was generally “S”-shaped. (3) From the perspective of national scale and different regions, the dominant factors affecting the spatial differentiation of ESV were different, and the interaction among multiple factors was significantly stronger than that of a single factor. The findings of the study can provide more scientific decision-making services for China in order to promote regional environmental protection and develop ecological civilization.

“…Discussion over this definition has been ongoing, although the generally accepted definition of ecological security includes two levels: a broad sense and a narrow sense [14,15,18] . Broadly, a high level of ecological security denotes a region that is not threatened in terms of human life, health, basic rights, sources of life, necessary resources, social order, and the human ability to adapt to environmental changes [17] . In other words, it is defined as the security state of a complex artificial ecosystem composed of natural, economic, and social factors [15,19,20] .…”

Africa, the second largest continent in the world, has achieved remarkable economic and political results through exploration and positive development. Ecological security comprehensively reflects the health and integrity of an ecosystem, and it is broadly defined as the security state of a complex artificial ecosystem composed of natural, economic and social factors. Ecological security determines the potential for sustainable development in Africa, especially with its rapidly developing economies. However, there is a lack of information on the ecological security state of the continent as a whole. In this study, we constructed an evaluation system based on a pressure-state-response model and evaluated the ecological security state of all 54 African countries. The results showed that, at the national level, the ecological security state of the countries in Africa differed, as did their spatial and temporal variations from 1995 to 2016. In general, African countries showed relatively good ecological security. The years 2007 and 2001 were the worst and best years, respectively, in terms of ecological security during the study period. At the regional level, North Africa and West Africa had the best and worst ecological security, respectively.
