This paper uses the three industries data and input & output model to analyze the overall industrial structure level and industrial correlation in Xinjiang, and finds out that Xinjiang is positioning at the para-industrialization stage led by the second industry, with a good developing trend, gaining some achievements in industrial structural adjustment. Issues are marked by irrational developing direction of the three industries that the first industry has a poor basis, easily subject to other industries, the second industry is still high-energy-consuming, high-pollution, low-technology without supports by high-technical industries, the third industry is lagging with low technicians. This paper presents suggestions on boosting the first industry, adjusting the second industrial structure, and developing the potential of the third industry, aiming at optimizing the third industrial structure and realizing long-term stable economic development in Xinjiang. 

This paper, based on 15 soil samples in 5 profiles around a typical development well in the southern Renqiu Oilfield, measures the polycyclic aromatic hydrocarbons (EPA’s controlled 16 PAHs as perference) via gas chromatographymass spectrometry detector (GC-MS), with the results indicate that the soils in nearby the well have been greatly contaminated. The total PAHs declines with depth, and with a peak at 20 cm in depth. The lowring PAHs such as Naphthalene, Fluorene, Anthracene and Phenanthrene and so on have a big proportion, of which the Naphthalene is the most. The PAHs decreases with rings, but the highring PAHs have an increasing proportion towards the well. The lowring PAHs are distributed chiefly at a depth of 0~20 cm and the middlehigh ones at 20~30 cm.
