摘要:

毛刺锦鸡儿(Caragana tibetica)群落是一种仅分布于亚洲中部地区, 处于荒漠草原地带向荒漠带过渡的植被类型。毛刺锦鸡儿群落在其分布区内有着特殊的生态价值。该研究报道了内蒙古、青海和西藏调查的55个毛刺锦鸡儿样地数据。(1)毛刺锦鸡儿群落共记录到142种植物, 分属35科82属, 物种组成以禾本科、豆科和菊科植物为主, 其中灌木、半灌木35种, 多年生草本72种, 一、二年生草本35种。(2)区系地理成分以戈壁-蒙古分布种为主(17.61%); 根据物种存在度等级划分, 其中I级(0-20%)的物种有126种, 占物种总数的88.73%, 多为群落中的偶见种; 生活型以地面芽植物为主; 水分生态类型中, 旱生植物(50.00%)和强旱生植物(14.79%)占优势。(3)根据毛刺锦鸡儿群落物种的生活型和优势度将毛刺锦鸡儿群落分为毛刺锦鸡儿-禾草群丛组、毛刺锦鸡儿-葱类群丛组、毛刺锦鸡儿-杂类草群丛组、毛刺锦鸡儿+灌木-禾草群丛组、毛刺锦鸡儿+灌木-杂类草群丛组、毛刺锦鸡儿-半灌木-禾草群丛组、毛刺锦鸡儿-半灌木-葱类群丛组、毛刺锦鸡儿-半灌木-杂类草群丛组, 进一步划分为34个群丛。

Abstract:

The Caragana tibetica community is a vegetation type distributed only in Central Asia region, in a transitional zone between desert steppe and desert. This community holds significant ecological value within its distribution area. This study reported the data of 55 C. tibetica plots surveyed in Nei Mongol, Qinghai and Xizang. (1) A total of 142 plant species were recorded in the C. tibetica community, belonging to 82 genera from 35 families. The community composition was dominated by Poaceae, Fabaceae, and Asteraceae, with 35 species of shrubs and subshrubs, 72 species of perennial herbs, and 35 species of annual or biennial herbs. (2) The floristic geographic elements were predominantly composed of species with a Gobi-Mongolian distribution (17.61%). Based on the degree of species presence, 126 species (88.73% of the total species) were classified as level I (0-20%), which were occasional species in the community. The life form was mainly composed of hemicryptophytes. In water ecological types, xerophytes (50.00%) and extreme xerophytes (14.79%) were dominated. (3) According to the life form and dominance of species, C. tibetica communities can be classified into 8 Association Groups: C. tibetica - Grass Association Group, C. tibetica - Allium Association Group, C. tibetica - Forb Association Group, C. tibetica + Shrubs - Grass Association Group, C. tibetica + Shrubs - Forb Association Group, C. tibetica - Subshrubs - Grass Association Group, C. tibetica - Subshrubs - Allium Association Group, and C. tibetica - Subshrubs - Forb Association Group. These Association Groups can be further divided into 34 Associations.
