Spontaneous combustion of oil shale is very common as a result of long-time exposure to the air in the fushun West Open-Pit Mine and West Dump. The PAHs in the high-grade off shale and its spontaneous combustion product were analyzed semiquantitatively by GC-MS in order to investigate their distribution in different states and their potential negative effects on the environment. Totally 57 and 60 PAHs and their alkyl homologues were identified in the two analyzed samples, among which the alkyl derivatives were predominant, taking up to about 65% in the total PAHs. Those low-molecular mass PAHs （3- or 4-ring） were the main compounds in the two samples. Ten of sixteen USEPA priority pollutant PAHs were detected in two samples, of which phenanthrene was the richest whose contents were 6.93% and 15.03%. Based on comparison of analysis results, the amount and contents of PAHs, except for triaromatic steroid group, were higher in the burning oil shale. So it can be determined that the effects caused by spontaneous combustion of oil shale would be more serious and that the effects of the fushun oil shale and its spontaneous combustion on the environment should not be ignored in the future work.

The updated study shows that the taphrogenesis of basement of the fushun Basin is not a kind of instantaneous process. It intensified gradually and went to extreme in the sedimentary stage of the Guchengzi formation, and then, it weakened rapidly and stopped soon afterwards; the depression did not take place after the taphrogenesis. On the contrary, it almost happened simultaneously with the taphrogenesis. The depression went at a high speed from the beginning of the sedimentary period of the Xilutian formation, and then weakened gradually in the sedimentary period of the Gengjiajie formation. The evolution course of the synsedimentary structure of the fushun Basin can be summarized as the following six stages: slow taphrogenesis and high speed depression to accelerated taphrogenesis and high speed depression to high speed taphrogenesis and high speed depression to retarded taphrogenesis and high speed depression to gradual halt of taphrogenesis and reduced depression to slow depression and gradual halt of depression. The tectonic evolution resulted in the formation of the 'lower taphrogenesis and upper depression' structure. The formation of the binary structure might be due to the suspension of taphrogenesis and the change of the regional structure stress field, but the depression kept going. The result of calculation combining the analysis of the synsedimentary structural frame, the back-stripping method of the subsidence history of the basin basement and the simulation of thermo-settlement history indicates that the great sedimentary space required by the 'upper depression part' consists of two parts, namely, 40% from compaction of sediments and 60% from slow depression of the basin basement during a long period of time. Gradual halt of the depression in the fushun Basin may be attributed to the reversal of the lithosphere hot-recession and gravity isostasy adjustment which may be the result of new hot-events in the depths and accompanied invasion of extremely t

Taking the connection zone between Shenyang and fushun as an example,urbanization indicator system was established from the aspects of population,economy,space and society,and the comprehensive evaluation indicator system of water ecological environment was also established from the aspects of water ecological environmental pressure,state and response. Based on the evaluation of comprehensive level of urbanization and the comprehensive quality of water ecological environment,their changing trends during 2000-2014 were analyzed,and the response model between them was established. The composite index of urbanization in the connection zone between Shenyang and fushun always increased from 2000 to 2014,and urbanization developed rapidly after 2004. The comprehensive quality of water ecological environment decreased firstly and then increased during 2000-2014. The response relationship between urbanization comprehensive index and water ecological comprehensive index during 2000-2014 could be expressed by a cubic curve.
