Abstract: This paper analyzes the bioavailability of soil heavy metal with morphology, geochemical facies, activity coefficient, migration coefficient, metastasis coefficient of soil heavy metal in the Puyu village, Huayin city. The research results show that: firstly, physiochemical properties of soil (include moisture content, available P, available K, total N, soil texture and so on) are key influencing factors for heavy metal activity, and correlation between total content and various morphology content of heavy metal too; secondly, antagonism and synergism are discovered among various heavy metal; thirdly, the correlation between the total content of heavy metal and physiochemical properties of soil such as PH value, moisture content, available P, available K, total N, soil texture is significant.

Abstract: In this paper, simulated experiments were performed in pots by using soil materials in different conditions of film remnant. Based on the research on soil microorganism quantity trends of soil enzyme activities were analyzed systematically: soil without film remnant, soil with film remnant for 5, 10, 15 and 20 years. By analyzing crop progress, the relationship with soil material was studied, in order to provide scientific basis for the variation laws between different conditions of film remnant and the activity of soil enzyme.
