Farming Structure System And Family Structure In Eastern Gansu Of Loess Plateau

Loess Plateau, China’s agriculture system "museum", therefore, with precipitation increases. Select Tianshui, Quzi, Shishe three regions, six villages, more than 200 farms, conduct household surveys, data collection. Research and agriculture changes in family structure and mutual relations of production system, analyze the role of labor, drawing conclusions by studying the follows:1, It’s indicated that the study area decreased per capita arable land with the increasing rainfall, planting structure consists mainly of forage to seed production transition, the proportion of cash crop increasingly grow with the increased rainfall. Three areas, two types of systems for crop production labor input time were significantly different(P=0. 00), and regional agricultural system type of interaction was signed(P=0. 03); livestock production labor time to devote significantly higher than the song and Sweetwater even rural community(P=0. 00), but the regional and agriculture system type of interaction was not significant.2, The economic performance of different types of farming systems, agricultural production within the scope of comprehensive comparison results. In 2014, cash invested in specialized crop system and integrated crop-livestock system of systems which are reflected SS> QZ > TS, cash output is SS> QZ> TS, economic benefits is SS> QZ> TS. Cash investment of TS> SS> QZ in 2015, for the cash-generating TS> QZ>SS, economic efficiency is QZ > SS> TS.3, The migrant farmers in the study area showing a certain regularity, young people in three study areas are labor-based output. Specialized crop systems to household income sources and income based business work, integrated crop-livestock systems revenues diversified. Each migrant farmers from the region prefer to present the township level and the level of the counties, The three areas of labor migration time are mainly 10-12 months. Workers are mainly in the construction industry and the service industries, transportation and energy industries account for a large proportion.4, The core family in the study area and three generations account for a large proportion, nuclear families accounted for about five percent in the family structure, the tendency of rural households scale miniaturization was evident. Three generations of an immediate family proportion have dropped slightly, joint family showed a decreasing trend. Family structure showing the proportion of trend is Core families> Three Generations family> Union Family> generational family> four generation family. There was no significant difference between the two types of family structure agricultural systems(p> 0.05).5,In the relationship of marriage, the couple separated in different places in a long-term, the low home frequency became the main factor in the study area why the marriage is unstable. Changes in marital relations has an impact on the family structure, which directly affect the labor expenditure and economic investment, leading to decomposition of families gradually lose their competitive advantages in agricultural production.6,The comparison between the labor, economic analysis, family structure among the three regions by two types of systems after analysis concluded that crop-livestock production conditions for the development of integrated systems farmers cropping system than farmers.This study was designed to guide farmers scientific planning of agricultural production, coordinating the relationship between family structure and changes in agricultural production between villages.
