摘要
本研究以新疆生产建设兵团第十师草原毒害草为研究对象,为查明其草原毒害草种类、分布及危害程度等,系统的评估毒害草发生及危害现状,为毒害草的防治与草原的可持续发展提供科学的理论依据.本研究采用踏查、样地调查等方法进行调查,并进行重要值及多样性分析.结果表明:第十师毒害草共有 63 种,分属 23 科 53 属,其中菊科毒害草种类占比最多为 19%;毒害草种群 Shannon-Wiener 多样性指数为 3.56,Simpson 多样性指数为0.96,Pielou均匀度指数为 0.86;毒害草空间分布格局整体趋向于均匀分布;优势毒害草为苦豆子、工布乌头、兔儿条、狭叶锦鸡儿、骆驼刺、麻叶荨麻、白刺、梭梭和蓝刺头,主要分布在 181 团、182 团、185 团.第十师草原毒害草种类较多,分布较广、危害严重,因此对其进行调查,摸清其种类、分布等对毒害草的防治具有重要意义.
Abstract
In this study,the grassland poisonous weeds of the Tenth Division of Xinjiang Production and Construction Corps was taken as the research object,and in order to find out the species,distribution and harm degree of the grassland poisonous weeds,systemati-cally evaluate the occurrence and harm status of the poisonous weeds,and provide a scientific theoretical basis for the prevention and control of poisonous weeds and the sustainable development of the grassland.Surveys were conducted by methods such as make a per-sonal inspection and sampling methods,and important value and diversity analyses were carried out..The results showed that there were 63 species of poisonous weeds in the Tenth Division,belonging to 23 families and 53 genera,of which the largest proportion of poisonous weeds in Compositae was 19%.The diversity index of Shannon-Wiener in poisonous weeds population was 3.56,the Simpson diversity index was 0.96,and the evenness index of Pielou was 0.86;The spatial distribution pattern of poisonous weeds tended to be evenly distributed;The dominant poisonous weeds were Sophora alopecuroides,Aconitum kongboense,Spiraea hypericifolia,Caragana stenophylla,camel thorn,Alhagi camelorum,Urtica cannabina,Nitraria tangutorum and Echinops sphaerocephalus,mainly distributed in the 181 regiment,182 regiment and 185 regiment.There are many types of poisonous weeds in the grasslands of the Tenth Division,with a wide distribution and serious harm.Therefore,investigating and understanding their distribution are of great significance for the prevention and control of poisonous weeds.
