摘要
为掌握日喀则市“生态型”野生牧草资源生境条件,以便能够进一步驯化,作为人工栽培牧草运用到日喀则草原生态修复工程中。通过多种调查方式掌握了4种日喀则常见野生牧草的生长环境,地上、地下长势,伴生种等基本信息。结果表明:4种野生牧草在西藏日喀则分布较为广泛,在海拔4 000 m以上水源条件匮乏条件下能够生长,生境多为沙土滩、灌丛草地,根系发达,防风固土作用强,具有较高的开发利用价值,有望挖掘成为日喀则市草原生态修复的乡土草种。
In order to master the habitat conditions of “ecological tvype”wild grasses resources in Shigatse,soas to further domesticate them anduse thermas atifially cultivated grassesforgrassland ecological restoration project in Shigatse.we have obtained basic information,such as the growth environment,aboveground and underground growth,and associated species of 4 common wild grasses in Shigatse through various survey methods.The results indicated that the 4 wild grasses species were widely distributed,can grow atan altitude ofover 4000 meters,wherewatersourceswere scarce.Their habitats are mostly sandy beaches and shrub grasslands.Theyhavewell-developed root system,and-strongwindproof and soil stabiliza tion.function.They have high development and utilization value.It is hopeful to excavate native grass species for grassland ecological restoration in Shigatse.
