Agriculture industrial structure of Wangdongguo watershed developed from unitary structure with planting food mostly in history to three parts structure including food

fruit and industry by exploring optimize pattern of agriculture structure and regulating agriculture industrial structure according to the characteristics of gully region of loess plateau. By increasing efficiency of water use and fertilizer resources

and gaining highly potential dryland output

average food per product in 15 years reached 4 100kg/km2

thus food could be self support basically with one person only possessing 733m 2 dryland field; Soil and water loss controlling and vegetation construction have been developed according to the characteristic of soil and water loss on the gully region of loess plateau. Now

soil and water conservation in Yuan physiognomy

slope and gully have been finished in high standard with plant covering rate reaching 43%

soil and water loss controlling rate reaching 92%

soil erosion modulus decreasing to 504t/(km2·a)

the controlling effect is notable.
