Phosphorus Source Tracing Techniques from an Interdisciplinary Perspective:Principle,Practice and Challenge
This article overviews the detailed exposition of the types and principles of watershed phosphorus source tracing techniques involving chemical characteristic tracing,isotopic tracing,microbial fingerprinting and modeling simulation,discussing their advantage and limitation,and the challenges facing these techniques.Although these techniques each have their merits in elucidating the complexity and dynamic nature of phosphorus cycling,their effective application is constrained by limitations in terms of technical approaches,the difficulties in diversity and comparability of the data interpretation frame-work and the high complexity of operations,and the reliance on advanced technologies.In addition,this article emphasizes the importance of interdisciplinary collaboration in driving technological innovation,data processing integration,and cost-ef-fectiveness balance.Summarily,by using amalgamating approaches and concepts from chemistry,biology and environmental science,it is possible in new perspectives to optimize the phosphorus source tracing techniques,srengthening the research and practical applications in the future.
