| 摘 要： | 对小兴安岭云冷杉林、兴安落叶松林、赤杨林、白桦林和阔叶红松林五种天然林生境土壤革螨的水平和垂直分布进行了调查研究。结果表明 ,广泛分布各生境的为峰革赛螨和小兴安岭螨 ,仅存在一种生境的种类较多 ,各生境仅存的种类越多 ,生境差异性就越明显。通过Jaccard相似性指数比较分析 ,兴安落叶松林和赤杨林生境土壤革螨群落最相似 ,云冷杉林和赤杨林生境及赤杨林和白桦林生境土壤革螨群落极不相似。土壤革螨的垂直分布总体上表现为表聚性 ,但各生境存在差异。土壤有机质和全氮含量高的土壤 ,土壤革螨的种类和数量都多。多数土壤革螨适宜在微酸性的条件下生存。

| Abstract: | Investigations were carried out on horizontal and vertical distributions of soil gamasida in Picea and Abies forest, Larix gmelini forest, Alnus hirsuta forest, Betula platyphylla forest and broad-leaved and Pinus koraiensis mixed forest in the Xiaoxing'anling. The results indicate that Gamasellus montanus and Zercon xiaoxinganlingensis are distributed extensively in all habitats, and only in one type of habitat has a huge variety of gamasida species and the more the species exist in the habitat, the more obvious the extensively habitats is. According to Jaccard's similarity index analysis, the soil gamasida communities in Larix gmelini forest are the most similar to those in Alnus hirsuta forest, and the soil gamasida communities in Picea and Abies forest and Alnus hirsuta forest are the least similar to those in Alnus hirsuta forest and Betula platyphylla forest. The vertical distribution of soil gamasida generally shows surface enrichment, but it is different in each habitat. The higher the organic matters and total N in soil , the more the species of soil gamasida and the bigger their populations are. Most of soil gamasida tend to live in slightly acid habitats. |
