“…The first step should be rational allocation of cultivated land resources, planned implementation of land development (Xu et al, 2010), farmland expansion, consolidation and fallow rotation (Yu-sen, 2002), in strict accordance with the Chinese red line for cultivated land protection and the ecological red line (Bai et al, 2021). At the same time, regions with weak CLP identified in the spatiotemporal pattern of CLP should be supported.…”

Inefficient utilization puts the productivity of cultivated land in a low development state. The key challenge for the efficient utilization of cultivated land is to clarify how various factors affect the spatial differentiation pattern of cultivated land productivity (CLP), to improve food production. However, evaluating the impact of the intensity and direction of CLP on a large-scale is a difficulty and there is a gap in knowledge. In this study, we used net primary productivity (NPP) to calculate the productivity of cultivated land and reveal its spatial differentiation. Also, this study examined the spatio-temporal heterogeneity of CLP and determined the effect intensity and the direction of effect of various factors on productivity, using the Songhua River basin (SRB) in China as a research case. We used genetic algorithms to modify and improve a neural network model of factor dimensionality reduction, combined with path analysis, cluster analysis, and regression analysis, to identify the main factors impacting CLP, synergies between these factors, and effect intensity and direction. The results showed that: (1) the area of cultivated land in SRB decreased, but the NPP of cultivated land area increased, during 2000-2020; (2) spatially, NPP was relatively low in the middle of the basin and gradually increased towards the periphery; (3) The main positive factors were the normalized difference vegetation index (NDVI), slope, precipitation, evapotranspiration, and total nitrogen, while the main negative factors were temperature, ratio vegetation index, and total phosphorus. Individual principal factors and the synergy between these factors gave CLP different temporal and spatial heterogeneity. Collaborative management of the threshold range of various influencing factors would improve the CLP. This novel information on

“…Soil erosion sensitivity: According to the basic principles of the general soil erosion equation and the existing assessment methods (Bai et al, 2021), indicators such as precipitation erosivity, soil erodibility, slope length and surface vegetation coverage were selected. The value assignment of each factor and the calculation formula are shown in Table S2.…”

“…Desertification sensitivity can be used as an important indicator to measure the degree of regional desertification and to determine desertification‐prone and sensitive areas. Specifically, indicators such as the dryness index and soil texture are used for the evaluation (Bai et al, 2021; Fan et al, 2017). The assignment of the value of each factor and the calculation formula are shown in Table S3.…”

Increased global floating populations is an important driver of local social‐ecological systems change, especially in ecologically fragile areas. However, the limitations of accurate data and specific methods have prevented the exploration of spatial visitation of floating populations and its risk of negative effects on fragile ecosystems. Here, we contribute to filling the knowledge gap in Tibet by adopting large‐scale geolocation data and incorporating factors such as landscape aesthetic value, ecological vulnerability and traffic accessibility. We found that 89.97% of the digital footprints of floating populations in Tibet have entered nature areas with low density of resident population, and 40.57% of them have entered ecologically fragile areas, leading to increased ecological risks. Nature‐based tourism is the main motive for floating populations to enter the ecologically fragile areas, accounting for 65.56%. The central government inadvertently exacerbated ecological risks by leading road construction, resulting in 64.62% of the ecological risks being located in areas with high traffic accessibility. The floating populations entering Tibet have the dual effects of promoting economic development and causing ecological risks. Therefore, it is urgent to put forward strategies to promote the sustainable development in Tibet based on the complex system of “nature‐based tourism–ecological protection–economic income–government behavior”.

“…Numerous studies have further proved that variations in LULC signi cantly impact ecosystem services (Ding et al 2021;Peng et al 2021). Moreover, the estimated impacts of LULC types on ecosystem services have been quanti ed (Bai et al 2021;Lamand, 2018). However, the impact of LULC on ecological services varies depending on the pattern and process of urban development.…”

Context: As an index of ecological well-being, Gross Ecosystem Product (GEP) estimates the value of final ecosystem services or the direct benefits people derive from the ecosystem. Objectives: In this research, we accounted for GEP and quantified the impacts of human activities on GEP in Shanxi, an ecologically fragile area in China, from 1990 to 2020. Methods: We associated all kinds of non-spatial data with spatial data and employed the local indicators of spatial association, the Sankey diagram, and the empirical orthogonal decomposition (EOF) to explore the spatio-temporal dynamic properties of GEP. The transfer matrix and gravity model were used to measure the response of the GEP to disturbance from human activities due to urbanization. Results: The results show that: (1) excluding 2010, the GEP possesses a growth trend and increased from 117.65 billion Chinese yuan (CNY) to 4594.89 billion CNY; (2) contrary to the steady growth of the GEP, the regions with high GEP generally tended to decrease, and the Green Gold Index (GGI) tended to increase and then decrease; (3) the spatial distribution of GEP in Shanxi is restricted, and there is a tendency for this restriction to decrease over time; (4) the decade from 2005 to 2015 has the fewest changes in the GEP of Shanxi; (5) the GEP field has a globally consistent type and a high-value-low-value inverse phase-type in the variation of the spatial distribution, and the first type accounts for 61.74% of the total variance in the EOF; (6) the variation of GEP in different cities may differ significantly over time, and the cities with more disturbance from human activities have lower GEP or higher variance in GEP; (7) the disturbance of residential land has a more significant impact on the GEP than the disturbance of industrial and mining land in Shanxi. Conclusion: Our research could provide important insights into ecological assessment in an ecologically fragile region, thus providing a policy basis for the conservation and better use of environmental resources.
