The agricultural product processing industry is the inevitable choice for the agriculture to realize the industrialization, integration and modernization. Although the agricultural product processing industry has become the bright point in Chinese economy development, the whole development level falls behind the developed countries. The thesis brings up that the inherent reasons that Chinese agricultural product processing industry falls behind is that Chinese agricultural product processing industry has not an integrated industrial innovation system and has not a proper innovation strategy. So this thesis deeply discusses how to construct innovation system of Chinese agricultural product processing industry and puts forward the innovation strategy in order to improve the technology innovation capability and the development level. 展开更多

The desert in northern China is one of important sources of loess and one significant source of material for sandstorms in Asia.The sand/dust that is transported from desert when sandstorms occur can destroy the growth of crops,cause serious losses and great harm to the economic construction and life safety,and cause natural environment pollution.Hence,it is very important to deepen the research into heavy metals in surface deposits at vulnerable ecological region of arid land of northern China to guide local industrial and agricultural development and improve environmental protection.In this research,10 heavy metal elements(Cr,Mn,Fe,Co,Ni,Cu,Zn,Cd,Pb,and Th)were tested and analyzed in 33 soil sample sites collected from the hinterland of the Tengger Desert,northern China.The results showed that the average abundance of Th exceeded its background soil value of China by more than 5.2 times,which suggests that the Tengger Desert is polluted by Th.In addition,based on principal component analysis,spatial differentiation,and correlation analysis,we identified the source of element with a coefficient of variation in abundance of greater than 0.5 or exceeding the background soil value of China.Principal component analysis and correlation analysis showed that the sources of heavy metals of Cr,Mn,Fe,Co,Ni,Cu,and Cd were similar,while those of Th and Zn were different.Moreover,based on the contents and spatial distribution characteristics of those heavy metal elements,we found that the formation of heavy metal elements enrichment areas is caused by industrial pollution,development of irrigated agricultural,geological,and geomorphic conditions,and the sedimentary environment in the study area.Our result can provide information on the environmental background values of soils in the hinterland of the Tengger Desert. 展开更多
