- Abstract:
- A comprehensive evaluation indicator system is needed to provide a complete and integrated assessment of the degradation degree of sloping cropland. We employed bibliometrics to perform statistical analysis on research studies involving cropland degradation. Frequency analysis was then used to identify high-frequency indicators to construct a total index set(TIS)for evaluation of the degradation degree of sloping cropland in black soil region. In addition, soil measurement data from sloping cropland in Baiquan County, were used as a basis to construct a minimum index set(MIS). The TIS included the following 11 indexes: A-horizon thickness, clay content, organic matter content, pH value, slope gradient, ridge-slope angle, gully density, bulk density, large water-stable aggregate content, soil cation exchange capacity, and crop yield. The first six of these were included in the MIS. In the studied area, undegraded soil, mildly degraded soil, and moderately degraded soil and above accounted for 12%, 12% and 76% of investigated sloping croplands, respectively. Slope gradient is one of the main factors affecting soil degradation, there is a synergistic relationship between slope gradient and ridge-slope angle. In addition, the application of pesticides, fertilizers and continuous cropping resulted in soil acidification.
