“…Thus, it can be concluded that there is a significant spatial correlation of agricultural non-point source pollution in China consistent with Xu et al [23]. By contrast of the results with no fixed effect model, spatial fixed effect model, time fixed effect model and bidirectional fixed effect model, and the results of R 2 and log-likelihood, the estimation result of the spatial-temporal double fixed model is the most appropriate for further research.…”

“…Many climatic factors could affect soil erosion, among which precipitation is the most closely related to agricultural non-point source pollution [22]. Additionally, with the increase in agricultural intensive management in China, the pollutants discharged by agricultural activities and rural life would cause persistent negative impacts on water, soil, air, biodiversity and agricultural ecosystems [23].

The influencing mechanism of agricultural non-point source pollution under intensive agricultural management is complicated. This paper adopted provincial panel data from 2008 to 2020 to estimate the level of agricultural intensive management, the agricultural chemical oxygen demand (COD), total nitrogen (TN) and total phosphorus (TP) emissions and emission intensity of agricultural non-point source pollution in different regions of China and analyze the spatial-temporal differentiation characteristics. Moreover, the mediation effect model and spatial spillover effect model were adopted to further explore the influence mechanism of agricultural intensive management on agricultural non-point source pollution. The results show that (1) The total emissions and emission intensity of agricultural non-point source pollution both showed an increasing trend, and these areas with high levels of agricultural non-point source pollution are roughly consistent with those areas with high-level of agricultural intensive management. (2) At the overall level, there were mediating effects of natural ecology, agricultural land management, planting and rearing structure and pollution control investment between the relationship of agricultural intensive management and agricultural non-point source pollution, among which agricultural land management was the largest. Additionally, there was significant spatial heterogeneity in the influencing mechanism of agricultural intensive management on non-point source pollution. (3) There were significant spatial agglomeration characteristics in both agricultural intensive management and agricultural non-point source pollution, which showed a fluctuating trend of “rise-decline-rise-decline”. (4) Agricultural intensive management has a significant positive spatial spillover effect on COD, TN and TP emissions of agricultural non-point source pollution. However, environmental regulation could cause agricultural non-point source pollution to be transferred nearby. Scientific understanding of the spatio-temporal differentiation characteristics and influencing mechanism of agricultural non-point source pollution under the agricultural intensive management model is conducive to providing reference for policy regulation.

“…The contribution rate of agricultural non-point source pollution is far more than that of point source pollution from industry and urban life, and has become the main pollution source of the most important river basins in China [ 8 ]. Agricultural NPS pollution has become the greatest problem in natural water, seriously affecting the sustainable development of agriculture and the environment [ 9 ]. Therefore, in order to fundamentally solve the problem of water pollution in China, we must place agricultural NPS pollution prevention and control into the important agenda of environmental protection [ 10 , 11 ].…”

“…The statistical data showed that the fertilizer amount in China increased from 41.24 million tons in 1999 to 54.04 million tons in 2019 [ 18 , 19 ]. The average application amount of fertilizer in China was up to 326 kg/hm 2 , more than two times the world average level [ 9 ]. The utilization rate of nitrogen (N), phosphorus (P), and potassium (K) had entered the international suitable range for the main food crops; however, the unused nutrients took a high ratio and were lost through runoff and leaching into the environment [ 20 ].…”

Lucid waters and lush mountains are invaluable assets. Resource-saving and environmentally friendly industrial structures, production, and living modes are pursued continuously for sustainable ecological development. According to the Second National Pollution-Source Survey, agricultural non-point pollution is still the most important source of the current water pollution. In order to improve the water environment and control the pollution, the meaning and content of the eco-agricultural industrial chain was introduced. Based on this conception, the eco-agricultural industrial chain, integrating a whole circular system with different sessions of crop farming, animal breeding, agricultural product processing, and rural living, was innovatively put forward to control the agricultural non-point pollution and protect the water environment systematically for the first time in this paper. The sustainable development was realized at a large scale from the reduction and harmlessness at the source, resource utilization in the process, and ecological restoration in the end. Core techniques were innovated based on the integration of agricultural industries to achieve the high-quality and green development of agriculture. The system included ecological breeding technologies, ecological cultivation technologies, as well as rural sewage treatment and recycling technologies, in the principle of reduce, reuse, and resource. Based on this, the agricultural production changed from the traditional mode of “resources–products–wastes” to the circulation pattern of “resources–products–renewable resources–products”. Thus, the final aim could be achieved to realize the material’s multilevel use and energy conversion in the system. The eco-agricultural industrial chain technology was proven to be efficient to achieve both the good control of agricultural non-point pollution and an effective improvement in the water quality.

“…The spatial spillover effect of environmental pollution refers to the first law of geography-the geographical proximity effect-which leads to the rapid expansion of pollutants with easy mobility to neighboring areas or even farther away, manifesting as a spatially contagious relationship [41,42]. ANSP is a "spillover" pollutant with a strong spatial spillover effect [42].…”

To promote sustainable agricultural development in small town areas during rapid industrialization, it is important to study the evolution of agricultural non-point source pollution (ANSP) and its influencing factors in small town areas in the context of rapid industrialization. The non-point source inventory method was used to study the characteristics of ANSP evolution in 14 small town areas in Gongyi City from 2002 to 2019. Using the spatial Durbin model and geographical detectors, the factors influencing ANSP in small town areas were analyzed in terms of spatial spillover effects and the spatial stratified heterogeneity. The results showed a zigzagging downward trend of ANSP equivalent emissions over time. Spatially, the equivalent emissions of ANSP showed a distribution pattern of being high in the west and low in the east. There was a significant positive global spatial autocorrelation feature and there was an inverted “U-shaped” Environmental Kuznets Curve relationship between industrialization and ANSP. Affluence, population size, and cropping structure positively contributed to the reduction of ANSP. Population size, land size, and industrialization were highly influential factors affecting the spatial variation of ANSP and the interaction of these factors was bivariate or nonlinearly enhanced. This study provides a feasible reference for policymakers and managers to develop reasonable management measures to mitigate ANSP in small town areas during rapid industrialization.
