| Abstract: |
| Rural areal systems face serve resource and environmental problems, such as shortages, environmental deterioration, ecological environmental pollution, and function degradation during the transformation development process. Rural pollution control is a crucial component of national rural revitalization strategy implementation and rural system sustainable development. The driving mechanisms of rural areal system pollution are discussed herein based on the summary of rural pollutant types and depiction of pollution evolution processes. Our results showed that water, soil, and air pollutants are the main pollutant types in rural areal systems. Rural pollutants gradually transform from single inorganic matter into organic-inorganic compounds. The evolution process of rural areal system pollution experiences stages of single, combined, and stereoscopic pollution. In spatial terms, the gradual decline of pollution sources and levels comes from suburbs and outer suburbs to general rural areas. Rural areal system pollution is driven by internal resources utilization, living and production activities, pollution governance system and external urbanization, industrialization, as well as global change and informatization. In the future, typical rural belt-region-sites should be chosen to study the pollution status, driving mechanisms, and relevant simulated evaluation of resource and environment effects to promote rural pollution control and policy innovation. |
