Construction method of ecological ditch for treating agricultural area pollution source
The invention discloses a construction method of an ecological ditch for treating agricultural area pollution sources, which comprises the following five steps: 1, ditch body size design, 2, planting hole design, 3, ditch body stability design, 4, plant configuration and 5, operation management. The erosion-resistant ecological ditch is constructed according to the principle that the ecological ditch firstly meets the requirements of farmland drainage and stagnation prevention and then gives consideration to ecological interception. In the aspect of structural design, according to the characteristics of ditch hydraulics and engineering mechanics, plant planting holes are reasonably distributed, the slope protection reinforcement technology is adopted, and the ditch body structure is stable through the anchoring effect between a root system and a three-dimensional plant net; and in the aspect of purification effect, the runoff nitrogen and phosphorus pollutant interception effect of the corn planting field is monitored and evaluated through a large-track-diameter flow experiment, and a later-period management countermeasure is put forward, so that the ecological purification function can still be fully played in the later period of operation, and the service life of the system is prolonged.
本发明公开了一种治理农业面污染源用生态沟渠的修建方法,五个步骤：第一步沟体尺寸设计、第二步种植孔设计、第三步沟体稳固性设计、第四步植物配置、第五步运行管理，按照生态沟渠首先应满足农田排涝防滞要求、后兼顾生态拦截的原则，构建了一种抗侵蚀型生态沟渠。在结构设计方面，根据沟渠水力学和工程力学特征，合理布设植物种植孔，并采用护坡加固技术，利用根系与三维植物网之间的锚固作用达到沟体结构稳定；在净化效果方面，通过大田径流实验，对玉米种植地径流氮、磷污染物拦截效果方面进行监测评估，并提出后期管理对策，确保运行后期仍能充分发挥其生态净化功能，延长其使用寿命。
