Abstract:: The southeast of the Loess hilly-gully region is one of the most suitable apple cultivation area in China. The governments implemented the de-farming slope farmland policy since 1999, the area had made great improvement both in ecology and economy by de-farming slope and enlarging the area of orchard. To explore the double effects of the orchard on conservation of water and soil, also on the farmers’ income increase, taking the Yangou watershed as an example, the paper assessed the orchard eco-economy coupling situation by measuring the sample plot and constructing assessment model, including the crown of an apple tree, orchard ground surface characteristic, soil erosions and the apple-planting income. Results show that: (1)The orchard mainly distributed over slope-land with gradients more than 15° in Yangou watershed, accounting for 79.06% of the total orchard area. The income of the orchard became the dominant source of the farmers’ general earning, accounting for 59.49% of total income in 2006; (2)The orchard has the same effect in conservation of water and soil as the forest. The average crown coverage in the orchard is up to 0.81, the area of fish scale pit and the controllable slope account for 38.96% of the total orchard area; (3)The variation of orchard eco-economy coupling index is consistent with the annual erosive rainfall, the more the erosive rainfall is, the larger the orchard output soil erosion will be. The higher the acquisition price or the yields per unit area, the lower the index and the better the degree of eco-economy coupling will be.
