Abstract: Jinzhou City is one of the largest crop cultivation cities, and the crop cultivation quality will directly affect the economic development in Jinzhou City. And the crop development is effected by the soil quality. In order to study the soil environmental quality and potential ecological hazards in the northwestern Jinzhou City, the authors took surface soil in Jinzhou City as the study object. The land quality geochemical assessment in the northwestern Jinzhou City was conducted based on soil data obtained from the 1∶ 250 000 geochemical survey of land quality. The geochemical grade of soil enviomment results show that most of the soil in the the northwestern Jinzhou City is in a risk-free state, but Cd has certain risks. The soil fertility characteristics of the northwestern Jinzhou City are rich potassium and low phosphorus and nitrogen. The comprehensive geochemical grade of soil quality in the surface soil of the northwestern Jinzhou City is mainly the third one, with an area of 8 037 km². The soil area of the second grade is 2 070 km², and the soil area of the first grade is 143 km². The geochemical characteristics of soil in the study area show that the Cd, Hg, Cl and Au is extremely mutant. This land is rich in Sr, Hg, Au, Mo, Cl and Cd, compared with land background value of Liao River Basin, and Cd is obviously higher than that in Liao River Basin. The soil type, parent material, and land use type could probably be the main influencing factors for Cd becoming a high risk of pollution. This research could provide basis for land resource planning, efficient and characteristic agricultural development, and ecological civilization construction of Jinzhou City.
