But so far, there have not report about forest soil microbe and soil enzymatic activity in westen sichuan. the study ' s object is bitch forest. spruce forest, fir forest, chrysanthemum alp, willow community and two couch grass, so the research of the soil microorganisma, soil enzymatic activity in the subalpine coniferous forests in western sichuan is significant to china. the result shows that : 1. in the soil, the relativity of the soil microbial puantity is very prominence, the relation with the quantity of the soil microorganism is that : bacillus > actinomyceto > fungi ; the amount of the microorganism of physiological group sequence ranging from high to low is : aminate > bacteriumazotobacter > denitrify bacterium > nitrobacteria > cellulose decomposing bacteria. under the different vegetable community, the microbial quantity is that : s5 > s7 > s6 > s1 > s2 > s4 > s3

The results showed that the mean proportion of polymorphic loci ( ppb ) of anabasis aphylla, which comprised 3 subpopulations ( 58 individuals sampled ), generated by 16 primers was 94. 56 %, the value of ppb of ceratocarpus arenarius, which had 4 subpopulations ( 80 individuals sampled ), using 16 primers was 98. 00 %. the paper had proved that the higher genetic diversity and the genetic differentiation existed in the populations of boih anabasis aphylla and ceratocarpus arenarius, while the latter had much more genetic diversity than the former. moreover, the study discussed the shannon information index and nei ' s gene diversity index of the two species natural populations, which indicated that there were more genetic variations within the subpopu

Seven plots selected from wanglang reserve were distributed in different types of forest and at different altitude, and different plot has different microclimate. soil property, microbial population, soil nutrient content of forest soil were determined in wanglang natural reserve, from may to october 2002 to july 2003, the ecological distribution of three main groups, bacteria, actinomycete and fungi were determined in the forest soils by the cell enumeration methods. six kinds of physiological groups, including ammoniation bacteria, nitrification bacteria, nitrosification bacteria, aerobic autogenesis azotobacter, aerobic cellulose - decomposing bacteria and anaerobic cellulose - decomposing bacteria were enumerated by the most - probable number ( mpn )

Based on the field investigations and laboratory examinations, a study of the population of the epiphytic dolichomitriopsis diversformis ( mitt. ) nog. in fanjing mountain reveals that its habitats are different among different host trees, but that there lies the common habitat characteristics of not more than 2m height from the bottoms of host trees trunks, less light, high relative humidity, slow wind speed, slow evaporation speed and long time of remaining humid in middle - lower tree bark ; that it is one dioecious moss species, the morphology is remarkably different between its perichaetium and perigonium, the number of its perichaetia is much more than that of its perigonia, its perigonium is difficult to find out, its sporophyte is upright, its seta is long and thin, its capsule is regular long oval and its calyptra is cucullate
