| 摘要: |
| 采用PFU法,于2004年夏季采集贵州羊昌河岩溶水生原生动物群落。生物样和水样进行室内岩溶水生原生动物培养、分离和鉴定,研究羊昌河岩溶水生原生动物群落的组成、功能营养类群及其生态类群特征。结果得出,羊昌河岩溶水生原生动物群落物种组成含17目33属36种;该岩溶水生原生动物群落含5个功能营养群,其中,光合营养群含有3个种,占总数的8.33%,细菌碎屑取食者群含有19个种,占总数的52.78%,食藻者类群含有11个种,占总数的30.56%,非选择性杂食者群含有1个种,占总数的2.78%,食肉者群含有2个种,占总数的5.56%;该岩溶水生原生动物群落的Maglaef多样性指数和异养性指数,分别是3.52和103。 |

| Abstract: |
| By the method of PFU, 48 samples and specimens of aquatic protozoa communities were collected from Yanchang karst rivers in Guizhou in summer, 2004.The results show:1)The aquatic protozoa communities consists of thirty-six taxa in thirty-three genera and seventeen orders; (2)Maglaef Diversity Index (MDI)and Hetero-trophic Index (HI)of aquatic protozoa communities are analysed in this paper; (3)The groups of ecological function include Photosynthetic autotrophs (P groups, 8.33%), Bactivores detritivores (B groups, 52.78%), Algivores (A groups, 30.56%), Nonselective omnivores (N groups, 1.78%)and Raptors (R groups, 5.56%). |
