However, in the process of application of grass-roots agricultural machinery, there are still some problems to be solved. For example, the lack of maintenance and blind application, especially when the busy farming season is approaching, the phenomenon of high-load operation of agricultural machinery often occurs, which seriously damages the service life of agricultural machinery. Based on the application of agricultural machinery at the grass-roots level, this paper further analyzes how to prevent the use of agricultural machinery, and puts forward some suggestions for the supervision of the application of agricultural machinery, which are only for reference and helpful to the peers.展开更多

Albeit the number of registered vehicles in Kolkatais much less compare to Delhi. Kolkata has encountered a decade longbattle against change of old vehicles and fuel types. So, this paper madean attempt to explore the dynamics of air pollution in the city speciallypre and post period of vehicle and fuel change in the city. The objectivesof the paper include looking at spatiotemporal change of air pollution inthe city. Besides, the paper additionally illuminates on the role of landuse functions and pollution in the city. The analysis shows that after theimplementation of regulatory measures air pollution in the city reduced tosome extent but effects of the measure gradually diminished. It is foundthat land use function as well as dynamics of metropolitan area plays crucialrole in the air pollution of the city.展开更多

Effective prevention and control of the development of non-point source pollution in crop production and protection of the environment of agricultural production areas from damage and pollution are important requirements for national ecological environment management and quality and safety of agricultural products. Based on this, this paper focuses on the analysis of the effective prevention and control measures to promote non-point source pollution in planting industry in China, and puts forward the requirements for the supervision of pollution sources for reference.展开更多
