Study on Soil Diversity of Liangucheng National Nature Reserve Based on Terrain

PurposeTo explore the soil distribution characteristics and the diversity distribution at different topography in Liangucheng National Nature Reserve.

MethodLandscape pattern indices such as soil richness, fragmentation, diversity, evenness and dominance on different terrain were calculated by ecological method, and the spatial distribution dispersion of soil on grid scale was calculated by improved Shonnon’s formula.

ResultThe soil in Liangucheng National Nature Reserve is mainly mobilized aeolian sandy soil, with the largest area and the highest spatial distribution dispersion. There are differences in soil quantity and spatial distribution on different topography. From plain area, mountain area, basin area to hilly area, soil richness index and Shannon ’s diversity index decrease, soil fragmentation index and evenness index increase first and then decrease; the spatial distribution dispersion was hill>mountainous region>plain>basin. The spatial diversity index of soil in the basin is the highest after rising and declining.

ConclusionThe flowing aeolian sandy soil is the dominant soil in the plain area, the mountain area and the hilly area. The soil in the basin area is evenly distributed, with high degree of fragmentation and no dominant soil. Using landscape ecology perspectives to explain the results of soil diversity, the results of the study can better illustrate the nature of soil distribution.
