The invention relates to an eco-stagnation and filtration system with a nitrogen removal function. The eco-stagnation and filtration system mainly comprises a stagnation zone and a filtration zone. The eco-stagnation and filtration system is constructed mainly from a municipal landscaping greenland. Through filling with a percolation matrix and plantation of specific plants, city overland runoff is delayed and is subjected to percolation.
