Abstract

After expatiating the guiding ideology, contents, standards and principles of eco-environment restoration based on enlarging terrace and de-farming, this paper discussed the planning method and technical flow of enlarging terrace and garden plot in a small catchment of loess hilly region by means of GIS spatial analysis technology, and then the planning method was applied in Yangou catchment. The result showed that it is practicabl, and the areas of newly-built terrace and garden plot in Yangou catchment are at least 295.06 and 4.61 hm2, so that the areas of basic farmland and garden plot reach 359.23 and 622.69 hm2. After the land use structure is regulated, the forest coverage is 48.87%, and the permanent vegetation coverage is about 75% in Yangou catchment, while sediment reduction benefit is above 80% in slope land. In agricultural development, Yangou catchment can yield 1 645.13 tons of food supplies, above 9 340 tons of apples, and can feed 7 500 sheep every year.
