摘要
根据2018年河南省草地清查的结果,对河南豫西地区的草地面积、草地类型、草地特点、利用现状和存在的问题进行了实地取样分析,为豫西天然草地的合理保护和多样化利用提供依据。按照农业部制定的《全国草地清查总体工作方案》,在原来草地调查的基础上,制定样地布设方案,对豫西乃至全省草地开展样方和样地调查,查清草地的植被特点、生产性状、生态特点和利用现状。结果表明:(1)豫西山区草地共有4类11个型,面积为300200 hm 2,占河南省草地面积的57.47%;(2)豫西天然草地中被子植物共有159科、1030个属、3230个种及变种;(3)豫西天然草地平均草层高度55.99 cm,平均盖度86.73%,平均产草量为3512.68 kg/hm 2,草地载畜量为726520.76羊单位。总之,豫西地区草地类型多样,饲草资源丰富,草地生产水平高,开发利用潜力极大。非常有必要根据草地的不同气候、地形以及生产特点,进行多样化综合保护和科学利用,加大草牧业发展,挖掘天然草地巨大的多功能生产潜力。
According to inventory results of natural grassland in Henan province in 2018,grassland area,types,characters,utilization status and problems were analyzed on the spot in order to provide theoretical basis for rational conservation and diversified utilization.Based on the Oveall Work Plan for National Grassland Inventory enacted by the Ministry of Agriculture as well as the past inventory results of natural grassland,inventory of sample plot layout scheme was established to make small quadrat and plot survey on vegetation characteristics,production characteristics,ecological characteristics and utilization status in western Henan.The results showed that grassland in western Henan was divided into 4 classes and 11 types,which was 3.0×105 hm 2,occupying 57.4%of all Henan grassland.There were 159 families,1030 genus,3230 species and varieties for the angiosperm in grassland in western Henan.For grassland in western Henan,average grass height was 55.99 cm,average grass coverage was 86.73%,average forage yield was 3512.68 kg/hm 2,carrying capacity was 726520.76 sheep unit.In conclusion,grassland in western Henan has great exploiting and utilization potential because of more varied grassland types,more flourishing forage resources,higher grassland productivity.It is necessary to conserve comprehensively and utilize scientifically natural grassland and exploit its great production potential.
