以植株长势、观赏性、花序美感、叶片颜色及成活率等作为观赏价值评价指标，以抗旱性、抗寒性、抗病虫、耐热、耐涝及土壤要求等生态适应性为评价指标，利用灰色关联分析，分别对宁波地区13种多年生观赏草品种的夏季、秋季和冬季的景观效果和适应性进行了综合评价。结果表明：蒲苇和矮蒲苇抗逆性较强，四季均能产生优良的景观效果。金线菖蒲和金叶苔草的春、秋和冬季景观效果很好。萱草是观花与观叶于一体的理想材料；细茎针茅在春末夏初表现非常突出，但是其他季节表现一般，且抗旱不耐涝，宁渡雨季较多，对其生长不利；其余观赏草均有一定的观赏价值，适合宁波地区生长。

Ornamental value and adaptability of 13 introduced perennial ornamental grasses were evaluated in Ningbo by gray-correlation analysis. Evaluation index for ornamental value were plant growth, ornamental value, inflorescence aesthetics, leaf color and survival rate etc. Evaluation index for adaptability were drought resistance,cold resistance, heat resistance, waterlogging tolerance, disease and pest resistance etc. The results showed that Cortaderia selloana and Cortaderia selloana ＂Pumila＂ with strong resistance could be used for landscape in full year;Acorus gramineus var. pusillus and Carex oshimensis ＇Evergold＂ showed good landscape effect except in summer; Hemerocallis fulva ＇Baltimore Oriole＇ was an ideal material for its ornamental flowers and leaves;The performance of Stipa tenuissima was absolutely outstanding in late spring and early summer.
