Abstract

Fractal features of soil particles, soil microbe number and enzyme activity were measured to understand the relationship between fractal dimension of soil particles and soil fertility under slope farmland (CK) and its four de-farming patterns, including Neosinocalamus affinis plantation (NAP), Bambusa pervariabilis × Dendrocalamopsis oldhami plantation (BDP), Alnus crenastogyne + Neosinocalamus affinis plantation (ANP) and abandoned farmland (AFL), in southern Sichuan province of China. The results showed that after 5 years’ de-farming, soil organic matter and clay (＜0.001 mm) contents, fractal dimension of soil particle, ratio of soil physical clay (＜0.01 mm) and physical sand (＞0.01 mm), bacteria, fungi, actinomycete and total microbe number, and invertase, phosphatase and urase activities followed the order of NAP＞BDP＞ANP＞AFL＞CK. The fractal dimension of soil particle and ratio of soil physical clay and physical sand were well correlated with soil organic matter, microbe number and enzyme activity, and there were close relationships between fractal dimension of soil particle and ratio of soil physical clay and physical sand. This indicates that the de-farming of slope farmland was beneficial for soil clay content increase,soil fertility and proportion of particle composition improvement; fractal dimension of soil particle could be used as a comprehensive quantitative index to evaluate soil fertility for slope farmland de-farming; the ratio of soil physical clay and physical sand in particle composition could reflect soil fertility characteristics and also could be used to evaluate soil fertility for slope farmland de-farming.
- de-farming pattern,
- vegetation restoration,
- fractal dimension of soil particles,
