The sixteen plants are firstly divided into six types according to evaluation grades and subject function statistical method:the first type is Cajanus cajan and Crotalaria mucronata,the best adaptability ,which can be used pioneer plant or constructive species; the second type is Cynodon dactylon,the better adaptability, which can be used constructive species ;the third type is Eragrostis curvula, Paspalam notatum,which can be used constructive species on rotten rock slope ; the forth type is kummerowia striata,Lotus corniculatus and Vitex negundo.The adaptability is centered,and can be used protection species and auxiliary species;the fifth type is Robinia pseudoacacia,Eremochloa ophiuroides,Vitex negundo,Lespedeza formosa,Leucaena leucocephala,Desmodium sequax, Rhus chinne- nsis,which can't be plant singly and be used accessory species;the sixth is Trifolium repens,which can be used pioneer plant.

根据评价边坡防护植物适应性的十个重要指标，首次运用隶属函数和聚类分析方法，对各供试植物的边坡适应性综合排序并分为六类：第一类为木豆和猪屎豆，边坡适应性最强，适宜作为先锋植物和建群种；第二类为狗牙根，边坡适应性强，适宜与豆科植物混播，作为建群种；第三类为弯叶画眉草和百喜草，边坡适应性较强，适宜与豆科植物混播，作为风化岩边坡的建群种；第四类为鸡眼草、百脉根和马棘，边坡适应性中等，适宜作为保护种与伴生种；第五类为刺槐、假俭草、荆条、美丽胡枝子、银合欢、波叶山蚂蝗和盐肤木，边坡适应性较差，不宜单独在边坡上种植，最好与速生型豆科草本混播，作为边坡防护植物群落的辅助植物；第六类为白三叶，边坡适应性最差，但因其出苗率高、生长速度快，作为先锋植物，起到前期覆盖坡面的作用。

The presence of REE tetrad effects in apatites and whole rocks of S-type granites has been reported by Sha and Chappell (1999) and Zhao et al.(1999), respectively. The REE tetrad effect in minerals, such as apatite, spessartite, beryl, alkali feldspar and spodumene, from all zones of Altay No. 3 pegmatite has been found remarkable, and the fractionations among isovalent incompatible elements in these minerals are also significant. This paper puts forward that the REE tetrad effect is one of the basic features of peraluminous melts and the origin of REE tetrad effect might be probably related to some processes prior to the formation of pegmatite magma. The immiscibile liquid separation between silicate melt and hydrosaline melt may be responsible for it.

由于阿尔泰3号伟晶岩脉各带磷灰石以及与其共生的石榴石、绿柱石、碱性长石、锂辉石矿物均存在明显的稀土"四重效应"以及相同电价、相似离子半径的不相容元素间存在显著的分异，并结合最近赵振华等(1999)和Sha and Chappell(1999)报道S型花岗岩全岩和单矿物(磷灰石、独居石、长石、黄玉等)均存在稀土"四重效应"这一现象，本文研究提出，稀土"四重效应"是富挥发分过铝质岩浆体系的一个基本特征，其机制既不可能由含稀土的副矿物早期结晶引起残余熔体相中REE含量变化的结果，也不能定性地归因于流体相与熔体相相互作用过程中稀土元素在流体/熔体之间分异的结果，而很可能与伟晶岩岩浆形成之前某些过程密切相关，S型花岗岩岩浆在液相线以上存在硅酸盐熔体与高盐熔体的不混溶液相分离有可能是过铝质岩浆体系产生稀土"四重效应"的主要原因。

We were interested in the shape of the complex in vertical cross-section.
