红壤丘陵森林生态系统矿质元素循环的计算机模拟

根据1983-1986年在江西泰和县中科院千烟洲试验站小区试验的数据,运用Basic 语言在联想386微机上,利用分室模型成功地模拟了植被分别为人工马尾松(Pinusmossoniana)、枫香(Liquidambar formosana)以及天然次生林内 P、K、Ca、Mg、Fe、Mn 等6种矿质元素的循环。通过计算机模拟,定量地刻划了在0-10年内上述元素在植物、动物、凋落物层与土壤中的运转状态,并给出了循环系数与系统中矿质元素达到稳定状态时的平衡点。

COMPUTER SIMULATION FOR THE MINERAL ELEMENT CYCLE IN THE RED SOIL HILL FOREST ECOSYSTEM

On the basis of the small-plot experimental data of the years 1983-1986 at the Qianyanzhou Experimental Station of the Chinese Academy of Sciences at Taihe County of Jiangxi Province and using the compartment model with the help of computer, the cycles of P, K, Ca, Mg, Fe and Mu in areas where the vegetation is Pine (Pinus mossoniana), Chinese sweet gum (Liqui-dambar formosana) and natural secondary forests (control area.) respectively are successfully simulated.The simulation results quantitatively describe how these elements move and transfer along the food chain from the plant, animal, litter layer to the soil within 0-10 years. The paper also calculates their cycle coefficients and the balance points at the time when they reach a stable state.
