- W2358471476 abstract "The functions of agro-ecosystem services is very important for local environment,especially in loess hilly and gully region.This paper,using data from Shanghuang valley of fragile loess hilly-gully region,and with the methods of mass and value assessment,analyzed the function of ago-ecosystem services.The results show that the total mass of agro-ecosystem services are 959.1 t in 1982,while the mass of crops is 600.9 t,which occupy 62.7% of that,however it reaches 2 581.9 t,which increases 197.35%,and the mass of corps is 689.4 t,which occupies only 24.17% of all the mass,while the forest,pasture,and fruit separately reaches 449.3,1 306.3,406.9 t.The value of agro-ecosystem service is 158.6 thousand Yuan,among it,the crop reaches 127.0 thousand Yuan,which occupies 80.07% of total value,however,which reaches 1 276.1 thousand Yuan,the value of crop,forest,pasture and fruit separately reaches 291.1,10.1,365.8 and 609.1 thousand Yuan.The function of agro-ecosystem service increased so much,the mode of agricultural production changes form single-crop farming to multiple agriculture." @default.
