摘要
目前我国对一些小流域的农业区面源污染积累较多经验，对城市区面源污染的研究比较少，这是因为随着城市化进程的加速，人类在城市上的活动能力较农业区大幅度地增加，从而导致城市地面污染种类繁多复杂。本文通过应用径流形成原理理论对其进行初步分析，提出现行适用的控制城市径流污染的方法为工程的和非工程的两大类。工程的方法指靠兴建工程措施来达到控制污染，如建沉淀池、渗漏坑、多孔路面、贮水池等；非工程方法指用加强管理来达到控制面污染，包括绿化、种草、清扫街道和清除下水道污染物等。
At present we have much experierce in non-point pollution of agricultural areas in some small drainage basins. The reason is that human beings have much more activities in the city than in the countryside along with the centralized urbanism and this leads to a great variety of urban surface-pollution. An original analysis on urban surface pollution by the theory of runoff formation is given in this paper. The suitable solution of controlling the urban runoff pollution can be divided into two groups: engineering and non-engireerng. The engineering way is to control pollution depending on construction of engineeing such as building precipitation tanks, infiltration channels, porous pavements, storage basins. Non-enginering way is by tightenness of management including offoresting, planting grass, sweeping away the pavements and clearing out the drain pollutant.
