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.
