光箨篌竹林的物质分配与养分循环

MASS DISTRIBUTION AND NUTRIENT CONTENT CIRCULATION OF SHORT ROTATION PHYLLOSTACHYS NIDULARIA FOREST

采用面上调查与定位观测相结合的方法，分析了海拔、母岩、土壤、坡向和坡度对光箨篌竹林生物量分配和生产力的影响，进而分析了竹林生态系统年际生物量分配和生产力变化，并讨论了不同经营技术组合对生物量分配、生产力、物质循环和Ｎ、Ｐ、Ｋ、ＳｉＯ２养分循环的影响。

Large scale investigations and permanent plot observations demonstrated effect of elevation. mother rock、soil and thickness、orientation and slope on biomass distribution and productivity of Phyllostachys nidularia forest ecological system. Analysis were made on annual biomass distribution and variation of productivity in bamboo forest ecological system. At last, discussions were made on effect of different management technique composition on biomass distribution,productivity、matter circulation and N、P、K、SiO2 circulation.
