- Abstract:
- Based on field investigation and indoor analysis, fine root dynamics and seasonal changes of soil moisture in Robinia pseudoacacia forest land on Weibei Loess Plateau was studied. Results from root investigation indicated that spatial distribution of fine root was different with site conditions, fine root on northern site had larger distribution regions. Results of soil moisture dynamics indicated that soil moisture distribution across profile could be divided into three layers: active soil moisture layer, stable-utilization soil moisture layer, and stable soil moisture layer. And site condition profoundly influenced soil moisture temporal and spatial distribution patterns. Further analysis indicated close relation was existed between soil moisture and fine root distributions. Suitable soil moisture environment promoted the growth of fine root, and consequenly showed higher productivity of above biomass; otherwise land productivity tended to be decreased.
