摘要
沙区景观表现为沙丘和低地交错分布.沙区常具独特的植物区系,含有特有和稀有植物.沙区植物丰富度降低和特有(稀有)植物消失问题近些年已受到很大关注,被列入国际生物多样性保护计划,很多国家和地区都对此开展了专门的研究.本文以近期发表的文献为基础,从植物多样性保护问题的提出、植物多样性形成机制、植物多样性保护途径、植物多样性研究与生态学理论的发展等方面论述了沙区植物多样性保护及其研究进展.沙区植物多样性保护应注意植物多样性保护目标的地域间差异(维持沙丘上的高植物丰富度还是保护特有或稀有植物)、流沙固定-植物多样性保护间的均衡、"植物多样性保护的量(高的植物丰富度)-质(特有或稀有植物出现)"间的均衡.还应将沙丘体和丘间低地视为一个统一体,研究干扰和生境破碎化对植物多样性造成的影响.
