| 中文摘要 |
| 明确了确定酸沉降临界负荷理论中的基本概念。通过建立生态系统在临界状态时淋溶液中碱度产生的静态质量平衡得到计算酸沉降临界负荷的基本方程,由此方程又导出计算酸度、潜在酸度、硫和氮等临界负荷的数学表达式,并讨论了根据对选择的指示生物有机体不发生危害的临界化学值计算淋溶临界碱度的方法,由此给稳态法建立了完整系统的理论体系。 |
| 英文摘要 |
| Some basic conceptions were clearly stated in the theory of determining critical loads for acid deposition. Basic formula to calculate critical loads for acid deposition was obtained by establishing steady-state mass balance equation for alkalinity production in leaching solution. From this basic formula, mathematical expressions to calculate critical loads for acidity, potential acidity, sulfur deposition and nitrogen deposition were derived. The methods of calculating critical alkalinity leaching by means of critical chemical values that will not cause harmful effects on a selected indicator organism were also studied. Therefore, a complete and systematic theory for steady-state mass balance method was presented in the paper. |
