Abundant and well-preserved macroalgae fossils have been discovered in silty mudstones and shales from the Middle Cambrian of Taijiang County, guizhou Province, china. Corallina Paraamphiroa siniansis gen. et sp. nov. in the Kaili Fm., is the earliest Corallina fossil, which usually coexists with other carbonaceous macroalgae fossils on the bedding planes of mudstone and shale and is different from the calcareous and phosphatized Precambrian-Cambrian thallus discovered in the Lower Cambrian of Siberia and the Doushantou phosphate rocks of Weng’an County, guizhou Province, china. The discovery of calcified thallus in the Kaili Fm. bears great importance on the study of phylogeny and evolution of early calcareous macroalgae.

[Objective] The aim was to analyze the current status and control measures of ecological restoration in Karst rocky desertification area of guizhou.[Method] The current status and existing problems of ecological restoration in Karst rocky desertification area of guizhou were studied firstly,and main control measures were put forward according to existing problems.[Result] At present,Karst rocky desertification area in guizhou has suitable ecological environment,obvious control results and rich control experience,and there exist many problems like ambiguous concept of ecological restoration,biased control emphasis,single control measure and serious water shortage due to lagging engineering *** measures mainly include combining natural restoration with artificial tending to speed up ecological restoration,reinforcing the restoration and rebuilding of development and construction project to prevent the deterioration of regional ecological environment,speeding up the construction of environmental friendly energy infrastructures to decrease the damage of vegetation by human activities,increasing industrial structure adjustment and greatly developing green industry and improving the investment in technological innovation to promote the rapid development of ecological restoration.[Conclusion] The study could provide scientific references for the ecological restoration in other Karst rocky desertification area in Southwest china.

为考察工作记忆子成分在珠心算过程中的作用与普通心算中的作用是否一样,采用2.3×2.混合实验设计,对受过珠心算训练与未受过珠心算训练的儿童在控制条件、语音环路次任务、视空间展板次任务三种条件下的心算成绩(反应时和正确率)进行比较。结果表明,视空间展板次任务对珠心算组的反应时和正确率都产生了干扰效应,说明珠心算过程中的存储成分更依赖于工作记忆中的视空间展板子系统。
