Abstract: From November 2004 to October 2005, twenty blood biochemical indices, i.e., total protein, serum albumin, serum globulin, total bilirubin, direct bilirubin, indirect bilirubin, blood glucose, serum urea nitrogen, serum creatine, total cholesterol, triglyceride, aspartate amino transferase, alanine amino transferase, alkaline phosphatase, serum creatine kinase, hydroxybutyrate dehydrogenase, lactic dehydrogenase, serum calcium ion, inorganic phosphate, and magnesium ion, of 10 femaleGrus japonensis adults in their wintering, reproduction, and migration periods in Zhalong Nature Reserve were analyzed by automatic biochemical analyzer. Significant differences (P<0.05 or P<0.01) were observed in the test indices except serum total protein, serum globulin, and blood glucose among the three life periods, which suggested that the serum total protein, serum globulin, and blood glucose could be used as the reliable references of blood biochemical indices of female G. japonensis, while the yearround dynamics of the other 17 indices reflected the physiological characteristics and ecological adaptability of female G. japonensis in its different  periods in one year. When using these 17 indices as the references of the blood biochemical indices of female G.  japonensis, the physiological period should be considered.

Key words: photosynthetic model parameter, temperature dependence, optimal temperature, scale, global warming.
