本发明涉及农田径流采集技术领域，特别是涉及一种基于降雨感应式片区农田径流动态采集系统。The invention relates to the technical field of farmland runoff collection, and in particular to a rainfall-sensing area farmland runoff dynamic collection system.
我国农田面源污染问题严重，呈逐年增加的趋势，第一、二次全国污染源普查结果显示，农业面源污染已经成为我国水环境污染的主要原因之一，有效防控农业面源污染是我国生态环境领域面临的重要课题。相关研究表明，由于化肥利用效率比较低，大量无法被利用的氮、磷养分随地表径流流失，污染土壤和水体，因此农业生产中氮肥、磷肥的损失是农业面源污染最主要的来源。The problem of farmland non-point source pollution in my country is serious and is increasing year by year. The results of the first and second national pollution source surveys show that agricultural non-point source pollution has become one of the main causes of water environment pollution in my country. Effective prevention and control of agricultural non-point source pollution is an important issue in our country. Important issues facing the ecological environment field. Relevant studies have shown that due to the relatively low efficiency of chemical fertilizer use, a large amount of unutilized nitrogen and phosphorus nutrients are lost with surface runoff, polluting soil and water bodies. Therefore, the loss of nitrogen and phosphorus fertilizers in agricultural production is the main source of agricultural non-point source pollution.
降雨引起的地表径流是农业面源污染的重要过程，农田中的氮、磷等营养元素随降雨径流向水体的迁移是氮磷流失的主要途径之一，亦是导致农业面源污染的主要原因。因此国内外研究者都十分重视对径流的研究和监测，而研究和监测过程必然涉及到径流水样的采集，使得径流采样装置得到了非常广泛的应用。目前对径流水样的采集分为人工实地采集和自动采样器采集，人工实地采集耗时耗力，且降雨的不确定性和采集地的偏僻性使人工采集更加困难。而自动采样器则存在以下几个方面的问题：无法实现对整个径流过程的连续采样，采集到的径流样品无法代表一次径流的整体情况；相关采样器针对单独田块，无法把握整片农田的产流情况；体积较大，携带困难，不便于多点的径流样品采集。因此明确一场降雨产生的径流过程，并了解污染物随径流产生的动态变化的规律，对农田径流进行科学的研究对于控制面源污染具有重要意义。Surface runoff caused by rainfall is an important process of agricultural non-point source pollution. The migration of nitrogen, phosphorus and other nutrients in farmland to water bodies with rainfall runoff is one of the main ways of nitrogen and phosphorus loss, and is also the main cause of agricultural non-point source pollution. . Therefore, researchers at home and abroad attach great importance to the research and monitoring of runoff, and the research and monitoring process inevitably involves the collection of runoff water samples, making runoff sampling devices widely used. Currently, the collection of runoff water samples is divided into manual on-site collection and automatic sampler collection. Manual on-site collection is time-consuming and labor-intensive, and the uncertainty of rainfall and the remoteness of the collection site make manual collection more difficult. The automatic sampler has the following problems: it cannot achieve continuous sampling of the entire runoff process, and the collected runoff samples cannot represent the overall situation of a runoff; the relevant sampler targets individual fields and cannot grasp the characteristics of the entire farmland. Runoff production situation; it is large in size and difficult to carry, making it inconvenient to collect runoff samples at multiple points. Therefore, it is of great significance to clarify the runoff process caused by a rainfall and understand the dynamic changes of pollutants with runoff. Scientific research on farmland runoff is of great significance for controlling non-point source pollution.
