Soil leakage loss is a special form of soil and water loss in karst areas and has been raising the research interest in the recent years. Owing to the invisibility and distinctiveness of soil leakage loss, how to effectively monitor it has become a tough problem. Through analyzing the existing methods, this study aims to assess their contributions to and deficiencies in understanding the law of soil leakage loss in karst areas. The results are produced as follows: (i) Simulation tests have given insights into the law and influencing factors of soil leakage loss under the double-layer karst structure, yet the small devices, the bedrock and soil transport, and the lack of vegetation, all impair their representativeness of the leakage loss realities of the vast karst area in the nature. (ii) ¹³⁷Cs tracer is beneficial to quantitatively trace soil erosion in homogeneous soil and to confirm the existence of soil leakage loss phenomenon in heterogeneous soil of karst rocky desertification regions, whereas the exact amount of loss is hard to obtain in karst heterogeneous soil through this method. (iii) Cave dripping tracer has offered a more scientific way to reveal the law of soil leakage loss and estimate the loss amount, but the amount measured with this method has a low accuracy and reliability resulted from the unknown surface seepage area. (iv) Scratching and erosion pins, with the mathematical models, are practicable to calculate the soil and water leakage loss. Yet several obstacles low their efficiency and reliability: the errors in the total soil erosion and the transportation ratio, and the unreliability in short-time monitoring. The other methods, underground river sediment monitoring and underground water turbidity, are also applicable in monitoring the SLL in karst areas, but still confront some obstacles, including the uncertain uniqueness of the underground river, the unreasonable sediment transport ratio, and the turbidity meter limitation.

水土流失是岩溶地区水土流失的一种特殊形式，近年来引起了人们的研究兴趣。由于土壤渗漏损失的隐蔽性和独特性，如何对其进行有效监测已成为一个棘手的问题。通过分析现有方法，本研究旨在评估其对了解喀斯特地区土壤渗漏损失规律的贡献和不足。结果如下：（i）模拟试验对双层岩溶结构下土壤渗漏损失的规律和影响因素提供了见解，而小型装置，基岩和土壤运移以及植被的缺乏，所有这些都削弱了他们对自然界中大片喀斯特地区渗漏损失现实的代表性。（ii）¹³⁷Cs示踪剂有利于定量追踪均质土壤中的水土流失，并有助于确定喀斯特石漠化地区非均质土壤中存在渗漏损失现象，而通过这种方法很难获得喀斯特非均质土壤的确切损失量。（iii）滴水示踪剂提供了一种更科学的方法来揭示土壤渗漏损失的规律并估算损失量，但是由于未知的地表渗流面积，使用这种方法测量的量具有较低的准确性和可靠性。（iv）带有数学模型的划痕和侵蚀销对于计算水土流失损失是切实可行的。然而，有几个障碍降低了它们的效率和可靠性：总的土壤侵蚀和运输比率的误差，以及短时监测的不可靠性。
