The contradiction between human and environment is prominent in China’s Loess Gully Region. Land engineering of gully land consolidation had effectively alleviated the farmland shortage after the Grain-for-Green Project, while the poor soil quantity, single structure and insufficient industrial integration had seriously restricted the coupling of rural human-environment in study area. Based on the perspective from soil-water relationship to rural areal system, this study explored the geographical engineering methods to the rural sustainable development. Results showed that the particle composition of Malan loess and red clay presented physical complementarity, red clay as natural soil amendment improved the clays, decreased the porosity and increased the fertility of farmland soil, and improved the crop growth and yield. Introducing forage rape to adjust plant structure of newly created farmland was conducive to develop the agricultural pattern of “vegetable plus oil”, “silage” and “vegetable plus silage”, its economic benefit could improve 28.85%, 21.16% and 48.49% than that of maize planting pattern respectively. Giving full play to the advantages of planting and breeding, the typical pattern of ecological industrialization including efficient planting-breeding pattern, leisure agriculture pattern and multiple comprehensive pattern had formed.
