摘　　要：通过对2019年江西省草地资源现状的调查和对不同类型草地植物地上净初级生产力开展监测,分析了江西省不同类型草地植物地上净初级生产力及不同群落主要优势种。对草地植物生物量高峰期监测,监测结果为:(1)江西省草地植物资源种类丰富,监测区共出现草本植物143种,隶属于39科,109属,主要为禾本科、菊科以及豆科植物;(2)不同地区草地植物ANPP差异较大,具体表现为萍乡>上饶>九江>吉安>景德镇>抚州>赣州>南昌>宜春;(3)全省林草地牧草利用潜力巨大,草地与畜牧业协同发展模式综合效益突出。Through the survey of the status of grassland resources in Jiangxi Province in 2019 and the dynamic monitoring of the productivity of different types of grassland plants,the productivity of different types of grassland plants and the main dominant species of different communities in Jiangxi Province were analyzed.The peak biomass of grassland plants was monitored,and the results were(1)Grassland plant resources in Jiangxi Province are rich in species,with 143 species of herbaceous plants occurring in the monitoring area,belonging to 39 families and 109 genera,mainly Gramineae,Asteraceae Bercht.&J.Presl and Leguminosae;(2)the productivity of grassland plants varies greatly in different regions,and the productivity is specifically Pingxiang>Shangrao>Jiujiang>Ji′an>Jingdezhen>Fuzhou>Ganzhou>Nanchang>Yichun;(3)the province has great potential for forest grass pasture utilization,and the comprehensive benefits of the synergistic development model of grassland and livestock are outstanding.
