Littered waste is a severe environmental problem. Although there have been many studies on wastes littered in the environments like beaches and seas, there is insufficient information on littered wastes in the urban settings. In this research, employing visual survey by the field litter counts method, littered wastes in six urban land uses in Qazvin, Iran were studied. The results showed that administrative and recreational land uses, by an average of 5.22 and 9.59 items per 100 m, respectively, had the lowest pollution, while low-density commercial land use had the maximum pollution by 185.96 items per 100 m. Urban littered waste ratios were not the same in various land uses: cigarette waste and paper and cardboard accounted for higher than 80% of the whole littered wastes in most studied land uses. The cigarette butt was also the most frequently litter in the city. In terms of environmental status, administrative and recreational areas can be defined as places with good conditions, while low-density commercial land use had bad conditions. Consequently, urban land use was acknowledged as a significant factor in the density of littered waste. More attention to cleaning the commercial land use to reduce the density of littered waste, and also finding methods to decrease littering waste by citizens, is a need in urban environment.

乱扔垃圾是一个严重的环境问题。虽然已经有很多关于在海滩和海洋等环境中乱扔垃圾的研究，但关于城市环境中乱扔垃圾的信息不足。在这项研究中，采用现场垃圾计数法的目视调查，对伊朗加兹温六个城市土地利用中的垃圾进行了研究。结果表明，行政和休闲用地污染最低，平均每百米5.22项和9.59项，低密度商业用地污染最大，每百米污染185.96项。不同土地用途的城市垃圾垃圾比例并不相同：在大多数研究的土地用途中，香烟垃圾和纸张和纸板占全部垃圾垃圾的 80% 以上。烟头也是这个城市最常见的垃圾。从环境状况来看，行政休闲区可以定义为条件较好的地方，而低密度商业用地则是条件较差的地方。因此，城市土地利用被认为是垃圾密度的一个重要因素。城市环境需要更多地关注清洁商业用地以降低乱扔垃圾的密度，并寻找减少市民乱扔垃圾的方法。
