中文摘要：

在我国,目前关于重金属的标准的水质基准都是基于总浓度制定,并在全国范围内采用统一标准,并不依据各地区具体水体状况不同而有所区别。因此,在我国开展针对地表水水体的重金属标准的修订研究是很有必要的。BLM模型是能够因地而异来制定和修订金属排放控制标准的很好的工具。基于BLM模型来制定水质基准,可以更加经济、合理、有效地控制金属向环境中的排放。在未来,生物配体模型既面临挑战又有着广阔的应用和发展前景,相信生物配体模型在我国水质基准建立的过程中会发挥越来越重要的作用。

英文摘要：

At present,the water quality criteria of heavy metals,which is not differentiated in the regions with different criteria,is based on the total metal concentration and unified in China.It is very necessary to do some research on the national standard for heavy metals of the ground water in different regions of China.With respect to the economic,rational,efficient and environmental friendly controlling of the heavy metals emission,the Biotic Ligand Model（BLM） is a promising method for establishing the national standard in varied regions.In spite of some challenges in improving and perfecting the BLM,it is believed that BLM will play an important role in the process of setting up the water quality criteria of national standard for heavy metals.
