中文摘要	为了解珍稀物种四爪陆龟 (Testudo horsfieldi) 栖息地植被情况,于2009年4月和9月在新疆伊犁四爪陆龟保护区,采用典型取样法进行2次常规群落学调查。结果表明:在保护区所设的40个样方中,共有65种植物,隶属22科56属。其中,十字花科植物种类最多,占16.9%,菊科占15.4%,藜科和豆科各占10.8%。保护区内的植物可分为5个株生长型、4个根生长型、5个生活型、3个水分生态类型。按四爪陆龟的食性分为4个食性型。在株生长型谱中,以直立型种类比率最大,占52.3%;分枝型和丛生型分别为24.6%和9.2%。根生长型谱以直根型种类比率最大,占76.9%;根茎型占13.9%。生活型谱以一年生植物最多,占50.8%,地面芽占 26.1%; 水分生态类型结构以中生型种类最多,占55.4%。四爪陆龟食物组成类型中,喜食性植物占21.5%。四爪陆龟保护区植物具有温带荒漠一年生植物气候特征和四爪陆龟喜食植物种类较少的特点。
英文摘要	In this study, vegetation in 40 sample plots in the Testudo horsfieldi Nature Reserve, Ili, Xinjiang was investigated in April and September 2009. The results reveal that there were 65 plant species in 56 genera and 22 families in the nature reserve. In which the proportion of Brassicaceae species was the highest and for 16.9%, than that of Compositae species and for 15.4%, and the proportions of Leguminosae and Chenopodiaceae species were all 10.8%. There were 5 plant growth forms, 4 root growth forms, 5 life forms and 3 water ecological forms in the nature reserve, and there were also 4 food forms of T. horsfieldi. In the plant growth form spectrum, the proportion of erect species was the highest and for 52.3%, the proportions of branch species and the tuft species were 24.6% and 9.2% respectively. In the root growth form spectrum, the proportion of taproot species was the highest and for 76.9%, and that of rhizome species was 13.9%. In the life form spectrum, the proportion of therophytes was the highest and for 50.8%, and that of hemicryptophytes was 26.1%. In the water ecological form structure, the proportion of mesophytes was the highest and for 55.4% of total. The food structure types were consisted of 21.5% faworite food. Climate in the Testudo horsfieldi Nature Reserve is the temperate-desert therophytes, and there are a few favorite food plants for T. horsfieldi.
