This paper, based on environmental Kuznets hypothesis, uses China's provincial panel data from 2001 to 2014 to establish panel smooth transition regression model, which is used to analyze the non-linear influence of industrial structure, financial development and urbanization level on eco-environmental pollution, and to discuss how to push green urbanization under variable regional industrial structures. Urbanization level rises by 1%, the environmental pressure falls by 0.548 6% at a lower industrialization, implying that urbanization may effectively suppress eco-environmental pollution. As industrialization level develops, urbanization level rises by 1%, the environmental pressure increases by 1.383 2%. Financial development, industrialization, and research and development input and energy consumption increment will worsen environmental pollution, which can be predominantly decreased by raising human capital. This paper verifies of the model stability.

This paper,aiming at studying the oilgas in the Cretaceous Yingcheng formation volcanic reservoir in Songnan gas field,which is characterized by deeply buried depth,complicated lithology, poor stratification, involuting horizontal distribution,and oilgaswater distribution in reservoir,applies seismic frequency attenuation and division frequency to predict the oil gas in the volcanic reservoir both vertically and horizontally.The result shows a highly consistency with the practice. And the spatial distribution of Yingcheng formation volcanic has been effectively identified.Oil gas can be reflected by detecting the amplitude attenuation gradient change of seismic reflection wave,and high frequency absorption attenuation,underpinning the oil gas reservoir description of Yingcheng formation volcanic reservoir.
