摘要: 太行山区位于黄土高原与华北平原之间,是我国生物多样性保护的重要优先区之一.本文以广义太行山涉及的108个行政县域为研究区域,基于太行山山地森林群落植物清查数据,系统分析了太行山山地森林群落的科属特征、区系组成、植物多样性地理格局及其丰富度热点地区.结果表明: 调查的778个样地得到太行山山地森林群落种子植物共计100科447属963种,其中,裸子植物3科7属12种,被子植物97科440属951种,生活型以草本植物占优势(71.1%);科的分布区类型以热带分布(38%)和温带分布(24%)为主,属的分布区类型以温带成分占主导(68.7%);太行山山地森林群落植物多样性的水平分布格局呈由西南向东北逐渐递增的趋势,群落物种多样性与经纬度均呈正相关关系,但不同生活型植物的多样性格局不相一致,草本植物多样性与经纬度呈正相关,而木本植物多样性与经纬度则无明显相关性;在垂直梯度上,太行山山地森林群落植物丰富度呈单峰分布,集中分布在400~1800 m的低中海拔地带,在1000~1200 m丰富度最高;基于群落清查数据绘制太行山山地森林群落植物丰富度分布图,鉴别出小五台山、云台山、太岳山、王屋山、中条山等山地为植物丰富度热点地区,应列入太行山优先保护的重点规划区域.

Abstract: Taihang Mountains is located on the eastern edge of the second step of Chinese topography, which is the natural boundary between Loess Plateau and North China Plain and is considered as one of the important priority areas for biodiversity conservation in China. We took 108 counties involved in the generalized Taihang Mountains as the research area to systematically analyze the characteristics of family and genus characters, floristic composition, geographical pattern of plant diversity and species richness hotspots at community level of mountain forests in Taihang Mountains. A total of 963 species of seed plants belonging to 447 genera and 100 families were recorded in 778 forest plots in Taihang Mountains. Within all the species, 12 species of gymnosperms belonging to 7 genera of 3 families, 951 species of angiosperms belonging to 440 genera of 97 families. Herbaceous plants (71.1%) was the dominant life form. The distribution types of families were mainly tropical (38%) and temperate (24%), and the distribution types of genera were mainly temperate (68.7%). The horizontal distribution pattern of plant diversity showed a trend of increasing from southwest to northeast. Species richness was positively correlated with the latitude and longitude. However, the richness patterns of different life-form plants were different, in that herbaceous richness was positively correlated with the longitude and latitude but that of woody plants was not. In the vertical gradient, plant richness of Taihang Mountains presented a single-peak distribution, which was concentrated in the low and middle elevations of 400-1800 m and peaked at 1000-1200 m. Based on the community inventory data, we mapped plant richness of Taihang Mountain forest community. The mountain areas such as Xiaowutai Mountain, Yuntai Mountain, Taiyue Mountain, Wangwu Mountain and Zhongtiao Mountain were identified as hotspots of plant richness, which should be included in the key planning and management areas of the Taihang Mountains priority protection.
