- W2391209397 abstract "In this paper we analyzed the development and affecting factors of terrace building in Ansai in 1950-2006,and then identified its contributions to the soil conservation,food grain production,rural income and agricultural development.Terrace construction in Ansai County could be divided into four stages,initial period,slow growth period,rapid growth period and relatively stable period.Conversion of sloping fields to terraced farmland improved the soil moisture and fertility conditions,stimulated the production inputs such as fertilizer,labor etc.,and thus greatly increased the grain yield.Observation data showed that the crop yield in terraced land is generally 1.72 times higher than slope farmland.Statistical analyses revealed that terrace building in the past decades has not only contributed greatly to the food grain production in Ansai,but also promoted a marked increase of rural income,particularly in the period before the year 1996,in which rural area income was mainly from cropping cultivation." @default.
