Municipal solid waste landfills need to be managed after closure. This so-called aftercare comprises the treatment and monitoring of residual emissions as well as the maintenance and control of landfill elements. The measures can be terminated when a landfill does not pose a threat to the environment any more. Consequently, the evaluation of landfill environmental compatibility includes an estimation of future pollution hazards as well as an assessment of the vulnerability of the affected environment. An approach to assess future emission rates is presented and discussed in view of long-term environmental compatibility. The suggested method consists (a) of a continuous model to predict emissions under the assumption of constant landfill conditions, and (b) different scenarios to evaluate the effects of changing conditions within and around the landfill. The model takes into account the actual status of the landfill, hence different methods to gain information about landfill characteristics have to be applied. Finally, assumptions, uncertainties, and limitations of the methodology are discussed, and the need for future research is outlined.
垃圾填埋场在封场后需要进行管理。这种所谓的封场后管理包括对残余排放物的处理和监测，以及对垃圾填埋场设施的维护和控制。当垃圾填埋场不再对环境构成威胁时，可以终止这些措施。因此，评估垃圾填埋场的环境兼容性包括对未来污染危害的估计，以及对受影响环境的脆弱性的评估。本文提出了一种评估未来排放率的方法，并从长期环境兼容性的角度进行了讨论。该方法包括：（a）在假设垃圾填埋场条件不变的情况下，采用连续模型预测排放；（b）采用不同的情景来评估垃圾填埋场内和周围条件变化的影响。该模型考虑了垃圾填埋场的实际状况，因此需要应用不同的方法来获取有关垃圾填埋场特征的信息。最后，讨论了该方法的假设、不确定性和局限性，并指出了未来研究的必要性。
