对1983年冬栽、1984年春栽冬小麦盆栽汞污染试验的部份结果,进行系统分析与模拟,充分估算土壤—作物系统与环境间污染汞的交换量,计算出实际参与系统内部运动的污染汞量,输入计算机同时计算配合十个函数方程,通过标准差、相关系数与显著性测验值的比较,迅速、准确地选出污染汞在系统内运动的数学模型,提高了模拟精度。用关联度分析方法可克服回归分析中的某些困难,较容易地判断出污染汞,籽粒产量,土壤性质与受污染部位的汞量之间的主次关系。
This paper systematically analyzes and simulates some of the results of winter wheat planting in 1983 and winter wheat in pot experiment in 1984, and fully estimates the amount of mercury exchange between the soil-crop system and the environment and calculates the amount of mercury that actually participates in the movement of the system Input the computer and calculate the ten function equations at the same time. Through the comparison of standard deviation, correlation coefficient and significant test value, the mathematical model of mercury movement in the system can be selected quickly and accurately, and the simulation accuracy is improved. Correlation analysis can be used to overcome some difficulties in regression analysis, and it is easier to determine the primary and secondary relationships between the levels of mercury pollution, grain yield, soil properties and the amount of mercury in contaminated sites.
