Soil samples were collected from Sankou, Taihuyuan (Xitianmu village) and, Hengfan towns, the main production area of Phyllostachys praecox stands in Lin`an, Zhejiang province where covered of 3.5•104 hm2 area. Soil profiles were excavated in 1 a, 5 a, 10 a, 15 a planting years of bamboo stands and each with 4 sites replications to study the variation of soil phosphorus content and distribution in due time of intensive management practices by yearly heavy fertilization and 30 cm thick organic mulch in winter season for higher yield and quality of Bamboo shoots. Soil P component was analysed by solution 31P NMR (AVANCE II 300MHZ BRUKER Co.) to give a sight of dynamics of various phosphorus components and its possible impact to soil and water environmental quality. Results indicated that, with the prolong of intensive management years of Phyllostachys praecox stands, the contents of soil total phosphorus (TP), available phosphorus (AP) increased steadily up to P 1.96~2.01 g kg-1 and P 458~468 mg kg-1, respectively. However, the increase of soil organic phosphorus (SOP) was relatively small. But all of the TP, AP, SOP contents showed gradually decrease from top layer > middle layer >> bottom layer in a soil profile which revealed that the soil phosphorus was enriched on the surface layer. The ratio of SOP to TP is relatively low as only 29%~20% and showed that it was gradually going down as the planting year prolonged. Data from the solution 31P NMR analysis revealed that inorganic orthophosphate was represented a significant proportion of the total P content, and the content of orthophosphate monoesters were lower but they increased with the planting years prolong. While contents of those orthophosphate diesters and pyrophosphate esters were a little, which revealed that the increase of SOP was quite low during the period of studied Phyllostachys praecox stands. Due to the high soil available P in Phyllostachys praecox stands of studied area, we suggested that any further P fertilizer application should be stoped immediately till to the AP lower down to resonable level , soils have accumulated enough P for high yield and quality bamboo shoots production of next 3～5 years , it is not only save the valuable resources of P but also benefit in reduce the potential risk to soil and water pollution.
