摘要：【目的】明确新疆伊犁河谷地区的生物多样性组成、空间分布和保护现状,为该地区的生物多样性保护和管理提供参考依据。【方法】基于文献资料的收集和查阅,以伊犁河谷分布的主要野生生物类群(包括维管植物、苔藓、地衣、大型真菌、昆虫、脊椎动物)为研究对象,整理了该地区生物物种名录及其县级地理空间分布数据,并基于此统计了该地区主要生物类群的数量组成特征及保护物种数量特征,分析了该地区物种多样性及县域保护优先等级的空间分布格局。【结果】1)该地区分布的主要野生生物共计3945种,隶属于445科1627属。其中,维管植物数量最多,占统计物种总数的52.7%;2)6类生物科级组成中均以寡型科数量占比最多,单型科次之,大、中型科最少。各类群中,大、中型科包含的属和种的数量占比较高;3)不同类群的物种多样性存在明显的空间差异。县域水平物种多样性不一致,伊宁县物种组成最丰富,包含了该地区74.8%的物种;4)该地区保护物种共计294种,占统计物种总数的7.5%。类群保护空缺较大,尤其是地衣、大型真菌、苔藓和昆虫。空间保护空缺以尼勒克县和昭苏县最为突出。【结论】伊犁河谷是新疆生物多样性分布的核心地区,关于开展该地区生物多样性保护工作,建议:1)将该地区列为新疆维吾尔自治区生物多样性保护重点关注地区;2)在生物类群保护层面,优先加强对地衣、大型真菌、苔藓和昆虫的关注力度;3)在县域空间层面,优先关注尼勒克县和昭苏县。
【Objective】To clarify the biodiversity composition,spatial distribution and conservation status of the Ili River Valley region of Xinjiang,and to provide a reference basis for biodiversity conservation and management in this region.【Method】Based on the literature and references,we selected the major wildlife groups(vascular plants,mosses,lichens,macrofungi,insects,and vertebrates)distributed in the Ili River Valley.The list of biological species in the region and their county-level geospatial distribution data were compiled.Based on the data,the quantitative composition characteristics of major biological groups and protected species were counted.The spatial distribution patterns of species diversity and county-level conservation priorities in the region were analyzed.【Result】1)A total of 3945 species of wildlife were distributed in the region,belonging to 1627 genera in 445 families.Among them,vascular plants are the most numerous,accounting for 52.7%of the total number of species counted.2)The number of oligotypic families accounts for the largest proportion of the composition of all six biological family levels.The number of genera and species was relatively high in plurimotypic and mesotypic families.3)There were obvious spatial differences in species diversity of different taxa.Species diversity was not uniform at the county level,with Yining County having the richest species composition,containing 74.8%of the species in the region.4)A total of 294 species were protected in the region,accounting for 7.5%of the total number of species counted.There was a large gap in the conservation of biological groups,especially lichens,macrofungi,mosses,and insects,and in the conservation of space,especially Nilka and Zhaosu County.【Conclusion】Regarding the development of biodiversity conservation in the region,it is recommended that 1)the region be listed as a key area of concern for biodiversity conservation in the Xinjiang Uygur Autonomous Region;2)at the level of biological groups conservation,priority be given to strengthening the focus on lichens,macrofungi,mosses and insects;and 3)at the spatial level of county,priority be given to Nilka and Zhaosu County.
