摘　　要：目的:探索不同微生境对中国石蒜(Lycoris chinensis)生物学特性和物种多样性的影响,为其驯化栽培、资源保护和可持续开发利用奠定基础。方法:通过样方调查对不同生境中国石蒜种群结构、优势物种、观赏植物多样性及中国石蒜表观形态特征进行统计分析;并通过不同生境对比,测定不同生境下中国石蒜的野生居群微生境生物学特性。结果:野生中国石蒜群在不同微生境中的种群结构为乔 + 灌 + 草,植物群落共计37科45属45种,乔木层建群种为朴树、枫香;灌木层建群种为山茶、杜鹃;草本层建群种为赤车、积雪草、中国石蒜。植物群落中乔木灌木层种类较少,草本层中物种较为丰富,整体呈现草本层 】乔木层 】灌木层,样地之间存在明显差异,微生境中光照和坡度均对中国石蒜的影响整体表现为D3 】D1 】D4 】D2。结论:中国石蒜是一种极具开发潜力且对恶劣生境适应性极强的观赏植物,不同微生境条件下中国石蒜的表观形态和种群结构不同。Objective: To explore the effects of different micrononics on biological characteristics and variants of Lycoris chinensis, lay the foundation for their domesticated cultivation, resource protection and sustainable development and utilization. Method: Through the sample investigation, statistical analysis of the structure, advantage species, ornamental plant diversity and Lycoris chinensis in different Lycoris chinensis;And compare different habitats, Microbial Biological Characteristics of wild Group of Wild Groups in Lycoris chinensis in Different Habulous. Result: The population structure of wild Lycoris chinensis in different micronemia is arbor + shrub + Herbs;the plant community 45 species of 45 species, arbor is built into Celtis sinensis, Liquidambar formosana;the shrub floor is built into a Camellia japonica, Rhododendron simsii Planch.;herbal layer is built into Pellionia radicans, Centella asiatica, Lycoris chinensis. There are few types of trees in the plant community, and the species in the herb are relatively rich. Overall, Herbal layer >Treble >Shrub. There is a significant difference between the sample, the overall performance of light and slope in the micronon birth;the overall performance of China’s stone garlic is D3 >D1 >D4 >D2. Conclusion: Lycoris chinensis is a very development and potential and has a very strong ornamental plant, and different micronon birth conditions the identification form and population structure of Lycoris chinensis is different.
