摘要
以县级行政区域为单元，调查了山东省高等动植物濒危物种的种类、濒危等级及其县域分布状况，建立了各县域濒危物种名录，计算了各县域濒危物种丰度指数，分析了濒危物种空间分布格局，提出了濒危物种保护对策。结果表明：山东省濒危野生高等动物物种有80种，其极危、濒危、易危和近危物种种类分别为3、11、34和32种。濒危野生维管束植物物种有24种，其极危、易危和近危物种种类分别为1、6和17种。濒危野生高等动物在全省120个县域均有分布，物种种类在21．50之间变化；濒危野生维管柬植物仅分布在74个县域，物种种类变化范围在1-18之间。山东省濒危物种丰度指数较小，各县域濒危物种丰度指数变化范围在3．75％-6．76％之间。濒危物种多样性空间分布规律反映了山东省实际情况。
This study investigated the species, threat categories and distribution in counties of endangered higher plants and animals, by using the county-level administrative area as an evaluation unit. The list of endangered species was established in every county area, their abundance index was calculated, their spatial distribution pattern was analyzed, and then the countermeasures of protecting the endangered species were proposed. The results show that there are 80 endangered wild vertebrate species in Shandong Province, and the numbers which belong to CR, EN, VU, and NT realm are 3, 11, 34, and 32, respectively. There are 24 endangered wild vascular plant species in Shandong Province, and the numbers which belong to CR, VU, and NT realm are 1, 6, and 17, respectively. The endangered wild vertebrate species distribute in every unit of 120 counties around the province, and the species range from 21 to 50. There are 74 units where the endangered wild vascular plants can be found, and the species range from 1 to 18. In conclusion, the abundance of endangered species in Shandong Province is low, varying from 3.75% to 6.76% in different counties. The results of spatial pattern of endangered species were consistent with the actual conditions of Shandong Province.
