Chemical analysis and toxic tests were combined with benthic macro invertebrates community structure alternations. Based on tri-axial graphs together with relevant matrix of decision-making, the initial bio-responsive sediment quality criteria clearly indicated the situation of heavy metal pollution, and showed the dose-response relationships between heavy metal contamination and benthic biotics. Moreover, the SQC may provide some basic material for establishment of sediment quality standards and for follow-up remediation engineering in the area.

During early middle Jurassic period, Quemocuo formation in NQB was offshore lake deposition with marine feature, in SQB was shelf deposition, which indicted that an intense rifting and sea level rising with more large range, and consequently, eroding area was shrunk and deposition area was expanded.4. According to the result of stratigraphic surface features, division and correlation, and the paleographic characteristic, Qiangtang Basin during late Triassic -early middle Jurassic period could be divided into two basin developing stages with difficult tectonic nature, remnent epicontinental basin stage in Carian -early Norian of late Triassic and rifting basin stage in middle Norian of late Triassic - early middle Jurassic period respectively.
