Abstract

Abstract: In order to explore the effect of Leymus chinensis transplanting on the biodiversity and productivity of saline alkali grassland in Songnen Plain,a comparative experiment was conducted in the transplanting Leymus chinensis grassland. The results showed that the transplanting of Leymus chinensis enhanced plant species and the density of the grassland community. The total plant density under the transplanting of Leymus chinensis was 566.20 plant·m^-2,6.85 times as much as that in the control (82.60 plant·m^-2),and the difference between the treatments was significant (P<0.05),and the transplanting of Leymus chinensis increased the diversity index of Shannon-Wiener,the evenness index of Pielou and the richness of Margalf species. The total biomass of the community was higher than that in the control. In addition,the total biomass of the transplanting of Leymus chinensis was 357.77 g· m^-2,2.14 times as much as that in the control (167.34 g·m^-2),and the difference between the treatments was significant (P<0.05),which indicated that the transplanting Leymus chinensis increased the productivity of the plant community,and greatly increased the grassland output benefit, The total income was 3938.00 yuan·hm^-2 for the transplanting of Leymus chinensis,7.37 times higher than that in the control (534.40 yuan·hm^-2),and the difference between treatments was very significant (P<0.01).Transplanting technology of Leymus chinensis not only improved the biodiversity of the system,but also doubly increased the biomass and economic benefits,So it was a technical model which was worth of popularizing and applying in the saline alkali area of the Western Songnen Plain.

Key words: Leymus chinensis, Transplanting, Songnen Plain, Diversity, Productivity

摘要： 为探明羊草（Leymus chinensis）移栽对松嫩平原盐碱草地生物多样性和生产力的影响，通过对比方法开展羊草移栽试验。结果表明：羊草移栽提高了草地群落的植物种类和密度，羊草移栽处理下植物总密度为566.20株· m^-2，是对照（82.60株·m^-2）的6.85倍，处理间差异显著（P<0.05）；羊草移栽处理Shannon-Wiener多样性指数、Pielou均匀度指数、Margalf物种丰富度指数均高于对照，提高了群落生物多样性；除此之外，羊草移栽处理植物地上总生物量为357.77 g·m^-2，是对照（167.34 g·m^-2）的2.14倍，处理间差异显著（P<0.05），说明移栽羊草提高了植物群落的生产力，进而大大增加了草地产出效益，羊草移栽处理总收入为3 938.00元· hm^-2，是对照（534.40元·hm^-2）的7.37倍，处理间差异极显著（P<0.01）。羊草移栽技术能够在提高系统生物多样性的同时，实现生产经济效益的倍增，是一项值得在松嫩平原西部盐碱化地区推广应用的技术模式。
