Sports activities with local characteristics are increasingly becoming tourism hotspots to attract tourists, and analyzing their contribution to tourism attraction can help local governments adjust tourism policies and enhance the attractiveness of attractions. To this end, this paper analyzes the significance of combining characteristic sports activities with tourism, extracts public factors using factor analysis, and constructs a tourism attractiveness evaluation index system. On this basis, the importance of local sports activities was analyzed using IPA analysis. The results show that the importance score of cultural and sports activities reaches a high 4.12, and among the three-level indexes under it, local characteristic sports activities have the greatest contribution to tourism attraction, with an importance score of 4.265. This shows that local sports activities have an important contribution to tourism attraction, and they should be given attention.

The Qingdong area, located in Bohai bay basin, was suspected good exploration prospects. In order to study tectonic features and find out favourable petroleum prospects in the area, the gravity data at a scale of 1:50,000 were interpreted. This paper, through data processing and synthetic interpretation of the high-precision gravity data in the area, discusses characteristics of the gravity field and their geological implications, determines the fault system, analyses features of the main strata, divides structure units and predicts favourable petroleum zones. The results showed that the faults controlled the development of the Mesozoic and Cenozoic strata and the distribution of local structures in this area. The study revealed that the Qingtuozi uplift and the Kendong uplift in the north were formed in Mesozoic, and the Qingdong depression in the middle was the rift basin in Mesozoic and Cenozoic. Thicker strata in Mesozoic and Cenozoic developed in the Dongying depression and the Qingdong depression, so there is abundant hydrocarbon in these two depressions, and then the Guangligang rise-in-sag and the Qingdong rise-in-sag developed in the center in these two depressions are also favorable places for prospecting
