| 为探讨理论治理成本法在修复后未达到基线水平或现状污染水平超过基线水平但不需要修复情形下的应用程序和方法，本文对理论治理成本法的理论基础、研究进展及应用程序进行探索，并以农田生态环境损害为例开展应用研究，以植物修复效率、规模为自变量构建理论治理成本函数，结果表明：影响植物理论治理成本函数的最主要变量为修复年限（Ni）和受损害区域面积（Ai）。对于已经确定的受损害地块，治理成本的大小主要决定于影响修复年限的植物修复效率（即mi）的高低。研究表明，植物修复理论治理成本法较适用于农田损害的损害价值量化，但受植物生长条件、损害程度等因素影响，理论治理成本低于实际治理成本。 |

| The study sought to better understand the application procedures and methods of the theoretical treatment cost method when the baseline level is not achieved after remediation or when the current pollution level exceeds the baseline level, but does not need remediation, The theoretical basis, research progress, and application procedures of the theoretical treatment cost method were explored. Application research was performed with farmland ecological environment damage as an example to construct the theoretical treatment cost function with phytoremediation efficiency and scale as independent variables. The results revealed that the most important variables affecting the theoretical treatment cost function of plants are the repair period（Ni）and the area of the damaged area（Ai）. For the damaged plots that have been identified, the size of the treatment cost mainly depends on the phytoremediation efficiency（i.e. mi）that affects the repair life. The findings indicate that the phytoremediation theoretical treatment cost method is more suitable for quantifying the damage value of farmland damage. However, the method is affected by factors that include plant growth conditions and degree of damage, and the theoretical treatment cost is lower than the actual treatment cost. |
