【摘要】：以新疆昭蘇縣域的沙爾套山天然草地為研究區(qū),對四季放牧草地的營養(yǎng)類型進行劃分,并對各季節(jié)放牧地利用期內(nèi)的草地營養(yǎng)成分變化特征等進行了分析。結(jié)果表明,沙爾套山四季放牧草地植被可分為4個大類(包括亞類),6個主要草地型,通過對不同草地類型草群的營養(yǎng)成分測定結(jié)果所劃分出的草地營養(yǎng)類型為氮碳型和氮型,氮碳型草地占主體地位。各季節(jié)放牧地因分布區(qū)草地類型組合、放牧時期和草群生長階段等不同,在放牧利用期內(nèi)草地營養(yǎng)成分組合形式發(fā)生變化,實際的季節(jié)放牧草地營養(yǎng)類型是:春季利用期內(nèi)草地存在3個營養(yǎng)類型,經(jīng)加權(quán)平均值計算營養(yǎng)類型為氮碳型;夏季利用期內(nèi)草地營養(yǎng)類型為氮碳型;秋季利用期內(nèi)存在3個草地營養(yǎng)類型,經(jīng)加權(quán)平均值計算營養(yǎng)類型為碳氮型;冬季利用期內(nèi)存在3個營養(yǎng)類型,經(jīng)加權(quán)平均值計算其營養(yǎng)類型為碳氮型。
[Abstract]:Taking the natural grassland of Shaertuoshan in Zhaosu County, Xinjiang as the research area, the nutrient types of grazing grassland in the four seasons were divided, and the variation characteristics of the nutrient composition of the grassland during the utilization period of the grazing land in each season were analyzed. The results showed that the vegetation of four seasons grazing grassland in Shaertuoshan Mountain could be divided into 4 types (including subgroup and 6 main grassland types). The nutrient types of grassland were nitrogen carbon type and nitrogen type by measuring the nutrient composition of different grassland types. Nitrogen and carbon grassland dominated. The nutrient composition forms of grazing land changed during grazing and utilization period because of different grassland type combinations, grazing period and grass growth stage in different seasons. The actual nutrient types of seasonal grazing grassland are as follows: there are three nutrient types in the grassland during the spring utilization period, and the nutrient type is nitrogen and carbon type calculated by weighted average value, and the nitrogen and carbon type in the summer utilization period. There were three types of grassland nutrients in autumn and three types of nutrients in winter, which were calculated by weighted average.
