对柴达木盆地5个盐生境的黑果枸杞进行了形态结构比较，探讨黑果枸杞为适应环境的响应。结果表明，不同盐分生境植株形态特征差异明显。全盐含量高、 K＋含量高、 Cl－／SO42－毫克当量比大的氯化物-硫酸盐型土壤中植株高大，冠幅小而紧凑，叶片长条形，横切面圆形，高度肉质化，叶肉栅栏组织形成“环栅型”结构，叶脉不明显，无叶柄，枝刺尖利、坚硬；全盐含量低、 Na＋含量高、 Cl－／SO42－毫克当量比值小的硫酸盐-氯化物型土壤中植株形态反之。但人工栽培后， K＋为主， Cl－／SO42－毫克当量比大的硫酸盐-氯化物型土壤中植株较高，叶变为披针形，栅栏组织呈条形，叶脉明显，具短小叶柄，枝刺变长、变软。

For understanding the morphological structure changes of Lycium ruthenium to adapt to the environment , the plant morphological structure and soil salt of L.ruthenium which grew at 5 different environment was studied in Qaidam Basin.The results showed that the plant morphological characteristics under different saline environment were significantly different.The high salt content, high content of K+, Cl-/SO4 2-mEq ratio and chloride-sulfate in the soil plant tall, the crown was small and compact, the leaf shape was long and thin strip, the transver sesection was circular , leaves became highly succulent , palisade tissue in mesophyll was “ring fence” type structure , leaf veins were not obviously, no petiole, branches were sharp, hard branch spines; Low salt content, high content of Na+and small Cl-/SO4 2-mEq ratio, type of sulfate-chloride in soil , the plant was contrary to the above.How-ever, after artificial cultivation, in high content of K+, high Cl-/SO4 2-mEq ratio, type of sulfate-chloride in soil, the plant was higher, lanceolate leaf with white short nap, normal palisade tissue structure with obvious veins, short petiole, longer and soft thorn.
