Abstract:
The six soil samples from the main Dryopteris fragrans producing areas of Heilongjiang Province (the second pool of Wudalianchi，the third pool of Wudalianchi，Laoheishan Volcano，Jingpo Lake，Folk Village，Jingbo Canyon) were studied using routine laboratory analysis and Biolog-Eco micro plate method to the characteristics of soil microbial communities.The soil nutrients，diversity index and the utilization of carbon sources in different habitats were analyzed.The results showed that：1) the soil organic matter content showed that Laoheishan Volcano was the lowest and there was no significant differences among other D.fragrans producing areas；the soil alkali hydrolyzable nitrogen content showed that the third pool of Wudalianchi > the second pool of Wudalianchi > Folk Village，Laoheishan Volcano，Jingpo Lake and Jingbo Canyon；the soil phosphorus content showed that the second and third pool of Wudalianchi was the lowest and there was no significant differences among other D.fragrans producing areas；the soil available phosphorus content showed that Jingpo Lake Volcano Group plots were lower and the Wudalianchi Volcano Group plots were higher；the total potassium content showed that Jingpo Lake and Laoheishan Volcano > the second pool of Wudalianchi，three pool，Folk Village and Jingbo Canyon；the available potassium content showed that Jingpo Lake > Folk Village > Laoheishan Volcano，Jingbo Canyon and the third pool of Wudalianchi > the second pool of Wudalianchi；the slowly available potassium content showed that Laoheishan Volcano > the third pool of Wudalianchi > the second pool of Wudalianchi > Jingpo Lake and Jingbo Canyon > Folk Village；the pH value among these D.fragrans producing areas ranged from 5.38 to 6.56，and the variation range was not the same，and the variation coefficient was 8.99.2) the soil microbial community functional diversity index of different places showed that Jingpo Lake > Jingbo Canyon and Folk Village > Laoheishan Volcano > the second and third pool of Wudalianchi.3) the principal component analysis (PCA) of soil microbial carbon source utilization in different D.fragrans producing areas showed that sugars，amino acids，polymers，carboxylic acids，amines and phenolic acids were the sensitive carbon source of D.fragrans soil microbial functional diversity.4) the cluster analysis showed that soil microorganism carbon source utilization model was similar between second and third pool of Wudalianchi and it was also similar between Jingpo Lake and Jingbo Canyon，and between Laoheishan Volcano and Folk Village.
