Spatial‐temporal evolution and influence factors of China’s agricultural non‐point source pollution discharge intensity in recent 40 years

Abstract

The excessive use of agricultural chemicals and the unreasonable use of agricultural wastes are the main problems encountered by China's agriculture department.However, the comprehensive study on the discharge intensity of China's agricultural non-point source pollution (ANPSP) under the long-term series has not been fully explored. On the basis of our previous research, the spatial-temporal characteristics and influence factors of ANPSP discharge intensity in China from 1978 to 2017 were analyzed. The results showed that the discharge intensity from 1978 to 2017 was on a declining curve and roughly underwent four stages, including the free development stage, reform promotion stage, market regulation stage, and policy incentive stage. In this process, the discharge intensity of COD, total nitrogen (TN), and total phosphorus (TP) was, respectively, declined to 1829.1 tons/10 8 yuan, 758.3 tons/10 8 yuan, and 100.1 tons/10 8 yuan. The regional discharge intensity has varied obviously in space as time goes by, showing the characteristics of spatial agglomeration, agglomeration weakening, spatial differentiation, and differentiation aggravation. The influence factor analysis indicated that under the background of implementing the traditional farming mode, increasing farmers' incomes, adjusting

Spatial Pattern Evolution and Influencing Factors on Agricultural Non-Point Source Pollution in Small Town Areas under the Background of Rapid Industrialization

“…(3) Selection of influencing factors Referring to relevant studies on the analysis of factors influencing ANSP, it can be found that scholars' selection of factors influencing ANSP mostly revolves around industrialization, affluence, population size, planting scale, and planting structure [52,[54][55][56][57]. Combined with the development background of rapid industrialization in Gongyi city, this study used industrialization as the core explanatory variable.…”

Public willingness to pay for farmland non‐point source pollution governance toward sustainable development: A choice experiment in Gansu, China

“…Effective governance of farmland non‐point source pollution (FNSP), which is related to multiple sustainable development goals (SDGs) such as food safety, ecological security, clean drinking water, and climate change (Abbass et al, 2022), faces enormous challenges. As the world's largest developing country, China's agricultural production has made remarkable progress in the last 40 years (Xu et al, 2022) but at the cost of severe FNSP, causing widespread social concern (Zou et al, 2022). In response, the Chinese government shifted its goal to the green transformation of agriculture in 2015 for sustainable development (Mao, 2021), wherein “one control, two reductions, and three basics” (CRB) † functions as the primary policy framework for FNSP governance (State Council Information Office, 2015).…”
