通过总结再生水地表入渗场地适宜性评价的相关文献发现，目前应用比较广泛的再生水地表入渗回灌方式中按回灌目的的不同可分为两种类型：一类以控制污染为目的，其中以农田灌溉方式为主，该类场地一般需要有较好的防污能力；另一类以补充地下水、获得优质回用水为目的，其中以土壤含水层处理系统为主，该类回灌场地不仅要求渗透层有很好的渗透能力，同时还要有一定的水质净化能力。以农田灌溉和土壤含水层处理系统为例，总结了不同回灌目的场地的适宜性评价模型的特征，并在此基础上提出了再生水地表入渗场地的适宜性评价模型中需要进一步研究的问题。%Based on the relevant literature,the infiltration of reclaimed water from ground surface could be divided into two classes according to the purposes. One of the purposes is to control pollution. Farmland irrigation is the main method. In general,site selection of this purpose needs high capacity to prevent groundwater contamination. The other one is to recharge groundwater in order to obtain good quality of reused water,such as soil aquifer treatment system. Site of this purpose needs high permeability and high natural attenuation ability of vadose zone. In this paper,farmland irrigation and soil aquifer treatment system were taken as examples to analyze and discuss the methods for site selection of different purpose. The question for further research was presented based on the above discussion.
