- Abstract:
-
Small Zhifanggou watershed in typical erosion environment was regarded as study case, and the soil samples of different farmland types were selected. Several indices were analyzed such as physical and chemical properties, and anti-erodibility. The results showed that physic-chemical properties and anti-erodibility differed significantly. The poor chemical properties were found in slope cropland and the the best properties were found in the greenhouse vegetable land. Organic carbon, total nitrogen, available N and available K behaved similarly, the greenhouse vegetable land was the highest, followed by flat field, terrace, dam land and gully land, the sloping cropland was the lowest. Compared with the sloping cropland, other farmland types had a better soil physical and chemical properties and anti-erodibility. Among these types, gully land and flat field increased more drastically than terrace, dam land and greenhouse vegetable land. The results suggested that other farmland types were managed more scientifically, and had a better soil fertile as well as anti-erodibility compared to the sloping cropland.
