准噶尔无叶豆的保护生物学研究

摘要/Abstract

摘要： 特殊生态系统下稀有物种的重要性及保育越来越受到关注。准噶尔无叶豆(Eremosparton songoricum)是分布在流动-半流动沙丘上的稀有物种,对维护沙丘稳定有重要作用。通过对准噶尔无叶豆群落结构、种群生态、生殖生物学特性和遗传结构及多样性等方面进行的研究,介绍了生存现状和有关的研究方法以及取得的重要成果,并从不同侧面阐明了该物种受胁机制以及进一步加剧受胁状态的内、外在因素,提出了保护策略和具体措施。以期为荒漠区珍稀濒危物种的保育提供借鉴,并对沙丘生态系统保护从个例分析的视角提供理论支撑。

Abstract: Rare species and their conservation in severe ecosystems have attracted more and more attention in recent years. Eremosparton songoricum (Litv.) Vass. is a rare woody shrub distributed in the mobile-dune areas in the Gurbantonggut Desert, Xinjiang, China. A conservation biological study on E. songoricum was carried out to examine the threatened ecological process and characteristics during the period from 2003 to 2009.The paper reviewed thoroughly the biological characteristics of tendency to rare status, geographic distribution, habitat conditions, population dynamics, features of sexual reproduction and asexual propagation, and genetic diversity and variation. In addition, some strategies and measures were put forward for conserving E. songoricum.

Key words: biological conservation, Eremosparton songoricum, rare species, sand dune, population dynamics, reproductive biology, genetic diversity
