Changes in soil properties and microbial communities regulated rhizosphere protistan assemblages. • Bacterial community was more sensitive to soil amendments than protists and fungi. • Soil amendments trigger the role of specific protistan taxa Cercozoa on microbial interactions. Understanding the responses of different rhizosphere microbial lineages to soil amendments during in situ remediation of Cd-contaminated soil is of great importance in the assessment of the restoration and crop health. Here, we evaluated the effects of lime (LM), biochar (BC), pig manure (PM), and a commercial Mg-Ca-Si conditioner (CMC) on the rice rhizosphere soil physicochemical properties and community assembly of bacteria, fungi, and protists in a six-year consecutive application of soil amendments field trial. Our results indicated that among the four amendments, the BC and CMC had the best efficiency in increasing soil ph, which were 5.2% and 16.2%, respectively. despite the differences in soil Cd concentrations is not noticeable, all the soil amendment treatments significantly decreased the proportion of available Cd in total Cd compared to the control. Soil amendments significantly altered the diversity of bacterial community, while they had no effect on fungal and protistan communities. Linear discriminant analysis effect size (lefSe) showed that the bacteria was more sensitive to soil amendment-induced changes. For protists, treatments with LM and BC changed the groups of protistan consumers, while treatments with PM and CMC significantly increased the relative abundances of protistan phototrophs. Co-occurrence network analysis revealed that soil amendments increased microbial network complexity and triggered the role of protists, especially for the predatory protists Cercozoa, on microbial trophic interactions. Further variation partitioning analysis revealed that edaphic properties, bacterial and fungal communities compositions together explained the 77% of the total variation i

If the theory of cyclical fluctuation can be applied to modern China, the economic development ofChina in this period can be seen as consisting of several stages. At each stage as well as in the wholeperiod, chosen index system is likely to help measure the growth rate. By vertical and horizontal com-parison, this paper will try to settle the disputes on China’s modern economic development.

Established in 1989 as a forum for its member countries or areas to discuss eco-nomic and related issues, Asia-Pacific Economic Cooperation (APEC) is nowbecoming an increasingly important regional organization. With a membership of18 countries and areas, it accounts for 34. 5％ of total world population, 50％ oftotal world GNP and 40％ of total world trade. What is more significant of APECis that East Asia is now the most dynamic region in global economic growth.
