摘要
通过野外调查研究了豫北低山丘陵区不同农田边界的植物丰富度、均匀度、生态优势度和多样性指数。结果表明:植物丰富度指数依次为灌草丛>水渠边>稀疏林地>路旁>果园边际>作物边界带,灌草丛物种丰富度显著大于其他边界类型,作物边界带的物种丰富度显著小于其他农田边界类型;植物均匀度指数依次为稀疏林地>灌草丛=水渠边>路旁>作物边界带>果园边际,稀疏林地均匀度指数显著大于其他边界类型,果园边际地的均匀度指数显著小于其他农田边界类型;植物多样性指数和生态优势度指数变化趋势一致,依次为水渠边>稀疏林地>灌草丛>果园边际>路旁>作物边界带,水渠边的生态优势度和多样性指数均显著大于其他边界类型,作物边界带的生态优势度和多样性指数均显著小于其他边界类型。灌草丛、路旁、水渠边、稀疏林地和果园边际地相互间的共有植物种较多,其物种相似系数均在0.7以上,而作物边界带与其他边界类型间的共有植物种较少,物种相似系数也较低,均在0.7以下,其中,作物边界带和灌草丛相似系数最低,为0.47。
Based on field investigation, plant species abundance and indices of evenness, diversity and dominance were analyzed in field margin systems in the hilly regions of northern Henan. The results show that species abundance is highest for shrub-grassland, followed by aqueduct margin, sparse forests, roadsides, orchard border and cropland border. Species abundance is significantly higher for shrub-grassland and lower for cropland border compared to other field margin systems. Evenness index is highest for sparse forests, followed by shrub-grassland, aqueduct margin, roadsides, cropland border and orchard border. Evenness index is significantly higher for sparse forests and lower for orchard border. Diversity and dominance indices are highest for aqueduct margin, followed by sparse forests, shrub-grassland, orchard border, roadsides and then cropland border. Diversity and dominance indices are significantly higher for aqueduct margin and lower for cropland border. There are much more common species among shrub-grassland, roadsides, aqueduct margin, sparse forests and orchard border, with similarity coefficients above 0.7. There are less common species between cropland border and the other field margin systems, with similarity coefficients below 0.7. The lowest similarity coefficient （0.47） is between cropland border and shrub-grassland.
