【摘要】 本研究分析了不同刈割处理对妫河下游湿地植物群落组成结构和多样性指数的影响,结果表明,三种刈割处理均改变了植物群落的优势种组成或重要值,对湿地植物群落结构产生影响.对不同群落生物量的影响表现出有增有减,各小区的不同处理与对照组间均具有显著或极显著差异.植物多样性指数在不同刈割处理和对照组之间比较,基本表现为增高趋势,丰富度指数、多样性指数的差异性显著与否不尽相同,但有显著差异的居多.更多还原

【Abstract】 This study by analyzing the effects of cutting treatments on Gui River downstream wetland plant communities indicated that:All of three kinds of cutting could change the dor minant species or the dor minance of dor minant species,and affect community structure.The biomass of different plant community after mowing was changed differently.Some of the community biomass decreased,and some have increased significantly.Species diversity index was changed significantly after cutting in many plant community,and the most was heightened.Or the difference was not significant to the contrast.更多还原
