The results showed that the mean proportion of polymorphic loci ( ppb ) of anabasis aphylla, which comprised 3 subpopulations ( 58 individuals sampled ), generated by 16 primers was 94. 56 %, the value of ppb of ceratocarpus arenarius, which had 4 subpopulations ( 80 individuals sampled ), using 16 primers was 98. 00 %. the paper had proved that the higher genetic diversity and the genetic differentiation existed in the populations of boih anabasis aphylla and ceratocarpus arenarius, while the latter had much more genetic diversity than the former. moreover, the study discussed the shannon information index and nei ' s gene diversity index of the two species natural populations, which indicated that there were more genetic variations within the subpopu
另外，通過rapd資料的聚類分析及相關性分析研究，發現無葉假木賊和角果藜自然種群的遺傳結構與綠洲沙漠過渡帶的微生境生態因子（主要是土壤因子）相關，其中無葉假木賊亞種群遺傳多樣性水平不僅與土壤含水量（ w ） 、鉀鈉離子濃度（ k + na ）和氯離子濃度（ cl ）呈顯著的正相關（ p 0 . 05 ） ，還與土壤中有機質（ som ） 、全氮（ nt ）和全磷（ pt ）含量呈顯著的負相關；同時，角果藜種群的遺傳多樣性水平與土壤中有機質（ som ）和全氮（ nt ）含量呈顯著的正相關，而與co _ 3 ~ （ 2 - ）濃度呈顯著的負相關；除此之外，其它土壤生態因子與兩物種遺傳多樣性水平的相關性均不顯著（卜0 . 05 ） 。
