Base on the theory of location quotient (LQ)and the characteristics of regional logistics, four quotients are constructed. This paper describes the regional distribution of China logistic agglomeration and its formation mechanism by the clustering analysis of statistical data of China Logistic Industry from 1999 to 2004. We conclude that spatial distribution in regional logistics agglomeration shows...
Effects of NaCl on seed germination, leaf gas exchange and seedling growth were investigated. The germination of P. tatarinowii seeds was delayed in the presence of NaCl, and was significantly inhibited when NaCl concentration exceeded 17 mM (1.0 g·L−1). NaCl treatments induced reductions of transpiration rate, stomatal conductance and net photosynthetic rate and their reductions were significant...
