摘要
采用现场调查和查阅相关文献的方法,对新疆博尔塔拉蒙古自治州境内的天然草场中的毒害草的种类、地域分布及危害后果等进行了分析研究。结果表明,博州地区天然草地面积为166.89万hm~2,可利用草地面积为162.54万hm~2,毒草分布面积20.33万hm~2,占可利用草地面积12.51%,年平均牲畜毒草中毒数超过6 000余头(只)。天然草地主要毒草有70种,分属15科,28属,对博州地区畜牧业生产造成危害的主要有无叶假木贼、骆驼蓬、乌头、针茅、醉马芨芨草等。通过调查分析,对博州地区毒害草的种类及分布有了基本的了解,为毒害草防控,保护草原生态环境提供了依据。
The paper analyzes and studies the species, geographical distribution, harm and others of poisonous weeds in natural grassland of Bortala Mongol Autonomous Prefecture, Xinjiang by the means of field investigation and referring to relevant documents. It turns out that, in Bortala Prefecture, natural grassland covers an area of 1.6689 million hm~2, of which, the available one is 1.6254 million hm~2, and the distribution area of poisonous weeds is 203,300 hm~2, accounting for 12.51% of the area of available grassland. Averagely,more than 6,000 domestic animals are poisoned by poisonous weeds every year. The poisonous weeds in natural grassland mainly include 70 species, respectively belongs to 15 families, 28 categories, such as Anabasis Aphylla, Peganum Harmala L., Aconitum Carmichaeli Debx., Stipa Capillata Linn., Achnatherum Inebrians, etc., causing great harm to animal husbandry in Bortala Prefecture. The species and distribution of poisonous weeds in Bortala Prefecture are basically learned through the investigation and analysis, providing reference for controlling of poisonous weeds and protecting ecological environment in grassland.
