摘　　要：西藏日喀则江萨国家湿地公园位于日喀则市桑珠孜区甲措雄乡,由年楚河及两边森林区域组成,主要保护湿地生态系统,规划面积1827.78公顷。研究采用样线和样方相结合的方法,对湿地公园野生植物资源进行调查研究。结果显示:(1)湿地公园典型植物群落有乔木林、灌木林或灌丛、水生及沼泽植物群落。(2)湿地公园主要植被可分为水生植被、沼泽植被、沼泽化草甸植被、灌丛、灌草丛和湿生木本植被6种植被型,9个植物群系组,26个植物群系。(3)湿地公园内共计有维管束植物44科、110属、164种。(4)植物科的分布区类型中世界广布型科数最多,占比达61.90%;优势科为菊科(Asteraceae,18种)、禾本科(Poaceae,18种)、毛茛科(Ranunculaceae,11种)、豆科(Fabaceae,13种)。(5)植物属的分布区类型中北温带分布型属数最多,占比达43.52%,其次为世界广布型,占比26.85%;优势属为杨属(Populus,2种)、柳属(Salix,4种)。调查研究结果可为湿地公园野生植物资源的保护利用及规划建设提供参考。Located in Jiacuoxiong Township,Sangzhuzi District,Shigatse City,Xizang,Jiangsa National Wetland Park is composed of the Nianchu River and forest areas on both sides,mainly protecting the wetland ecosystems,with a planned area of 1827.78 hectares.In this study,a combination of transect and quadrat was used to investigate and study the wild plant resources in the wetland park.The results showed that(1)the typical plant communities in the wetland park included arbor forest,shrub forests or shrubs,aquatic and swamp plant communities;(2)the main vegetation of the wetland park can be divided into 6 vegetation types,9 flora groups and 26 plant formations;and the vegetation types include aquatic vegetation,swamp vegetation,swampy meadow vegetation,bushwood,brush meadow,and wetland woody vegetation;(3)there are 44 families,110 genera and 164 species of vascular plants in the wetland park;(4)among the distribution area types of plant families,the number of widely distributed families in the wold is the greatest,accounting for 61.90%;the dominant families are Asteraceae(18 species),Poaceae(18 species),Ranunculaceae(11 species),and Fabaceae(13 species);(5)among the distribution area types of plant genera,the northern temperate zone has the largest number of genera,accounting for 43.52%,followed by the world’s widely distributed genera,accounting for 26.85%;and the dominant genera are Populus(2 species)and Salix(4 species).The investigation and research results can provide a reference for the protection,utilization,planning and construction of wild plant resources in the wetland park.
