| 摘 要： | 为了解红松洼自然保护区植物群落数量特征对短期围栏封育的响应,以当地草原植被为研究对象,采用样方法对封育区和放牧区植被生长状况进行调查.结果表明:围栏内外植物群落的基本组成未发生明显变化,围栏内外均以披针叶苔草(Carex lanceolata)、珠芽蓼(Polygonum viviparum)、地榆(Sanguisorba officinalis)和裂叶蒿(Artemisia tanacetifolia)等植物为优势种,围栏封育措施提高了草地群落高度、密度和地上生物量.围栏内外物种丰富度指数S、优势度指数DS、Shannon-Wiener多样性指数H和均匀度指数JP差异不显著.围栏封育2年植物群落的相似性系数和Cody指数的变化趋势基本相同,围栏内外群落具有较高的相似性. |

| Abstract: | An experiment was conducted to determine the response of grassland plant community quantity characteristics to short-term enclosure in Hongsongwa Natural Reserve by monitoring the community change of grassland plant. Both enclosed measure area and continuous grazing area were studied with the quadrat method.The results showed that the basic components of plant communities inside and outside the fence did not change significantly. In both areas, the dominant species were Carex lanceolata, Polygonum viviparum, Sanguisorba officinalis and Artemisia tanacetifolia, et al. The short-term enclosure increased vegetation height, density and above-ground biomass. The species richness index(S), dominance index (DS and H) and uniformity index(JP) of tested areas were not significant difference. The similarity coefficients and Cody indexes of plant communities had similar change tendency in 2 years, and plant communities inside and outside the fence had high similarity. |
