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。
