摘要

Farmers' livelihoods have different effects on farmers' inputs, farmers' production decisions, and farmers' land use behavior, that caused the difference of pesticide and chemical fertilizers application. Based on the farmers' survey data, the STIRPAT stochastic regression model and the gray relational grade were used to analyze the differences in the application of pesticide and chemical fertilizers in different livelihood types. The results show that:(1) There are significant differences in the application of pesticide and chemical fertilizers in different types, the pure agricultural type is the highest, the type one agricultural is the second highest, the non-agricultural type is the lowest.(2) Farmers' agricultural behavior has a significant effect on the application of pesticide and chemical fertilizers. With the increase of non-agricultural activities, the reduction of farmland scale, the decrease of the proportion of agricultural income, the amount of pesticide fertilizer applied by farmers is gradually reducing.(3)The influencing factors of pesticide application in different types of farmers are different. The pure agricultural type is related to the composition of household income, the type one agricultural is related to farmland scale, and the type two agricultural is related to all influencing factors.
