摘　　要：为治理外来入侵物种互花米草,江苏盐城湿地珍禽国家级自然保护区采用5种不同物理处理方法进行治理,通过后期监测发现互花米草治理效果显著。治理区的互花米草活株数、密度、盖度、鲜重和干重均有大幅度下降,分区1(深翻)和分区2(刈割+淡水水淹)治理效果较佳;珍禽候鸟监测发现10月份有220只/10种,11月份有155只/12种,且分区2能够吸引更多珍禽候鸟。为了保护本土植株生存空间、维护盐城湿地生态多样性、根除外来互花米草入侵,保护区互花米草治理效果显著,可大规模示范推广应用。In order to control the alien invasive species Spartina alterniflora,the Yancheng National Rare Bird Nature Reserve in Jiangsu adopted five different physical treatment methods.Post-treatment monitoring revealed significant control effects.The number of living Spartina alterniflora plants,density,coverage,fresh weight,and dry weight in the treatment areas all decreased significantly,with Zones 1(deep plowing)and Zone 2(mowing+fresh water flooding)showing better control effects.Rare bird monitoring found 220 individuals of 10 species in October and 155 individuals of 12 species in November,with Zone 2 attracting more rare migratory birds.The control of Spartina alterniflora in the reserve is effective,significantly protecting the habitat of native plants,maintaining the ecological diversity of the Yancheng wetland,and eradicating the invasion of Spartina alterniflora.This approach can be widely demonstrated and promoted.
