摘　　要：研究了采用清水、清水/再生水、再生水灌溉对不同绿地植物生理指标的影响。结果表明,再生水灌溉下大部分植物的相对含水率、净光合速率和叶绿素质量分数较高,且仅少数植物在3种灌溉处理下存在显著差异,说明促进了大部分植物的生长发育。而多数植物的相对电导率增高,但各项指标均未达到危害的标准,说明对一些植物产生了不利的影响,但没有产生危害。The effects of reclaimed water irrigation on biophysical parameters of greenbelt plants were studied under fresh water irrigation, fresh/reclaimed water irrigation, and reclaimed water irrigation. The result showed that： the relative water content, net photosynthesis rate and the chlorophyll content of most plants were higher under reclaimed water irrigation and there was significant difference for few plants among three irrigations, which showed reclaimed water irrigation could promote growth and development of most greenbelt plants. However, the relative conductivity of many plants were higher after reclaimed water irrigation, which showed that reclaimed water irrigation was bad for some greenbelt plants, but all biophysical parameters were not up to the endanger limit.
