| Based on the introduction of agricultural cleaner production, technology system design of planting cleaner production is discussed from five aspects of water-saving irrigation technology, fertilization technology, diseases and insects control technology, straw comprehensive utilization technology and plastic film pollution control technology. Cleaner production technology system of livestock and poultry raise is constructed from the aspects of source control technology, reduction technique in breeding process and end control technology. Thus, the implementation of agricultural cleaner production technology system has profound impact on the agricultural sustainable development in China. |

| We examine in a dynamic framework how public resources should be allocated to small-scale water protection efforts in agriculture or alternatively to investments in large-scale waste water treatment plants to control point source loads. The building of waste water treatment capacity is characterized by high set-up costs as compared to the operating costs. We determine the optimal timing of investment, the rate of nutrient load reduction from point versus non-point sources, and the optimal switching policies from control of non-point pollution only to control of both non-point and point sources. The results of the analytical model are illustrated with simulation of optimal abatement policies for the Finnish coastal waters in the Gulf of Finland. |

| Non-point source pollution arises from fertilizer application in China. This paper empirical test the major factors which affect fertilizer application amount using econometric models and micro-level data from Jianghan plain in Hubei province by year 2006. The results demonstrate that housemaster’s education level, family’s management scale, land fragmentation are major factors affecting farmer’s decision-making process. When farmers have consciousness of scientific fertilization, higher agricultural labor proportion, farther land distance, longer production period could decrease fertilizer application amount. In the field of agricultural public policy, training for technical generalization is helpful in reducing fertilizer consumption. |
