【摘要】 本文以高羊茅、紫花苜蓿、中华结缕草、黑麦草、白三叶、“胭脂红”景天和“金娃娃”萱草等七种地被植物为研究对象,对其在岩石专用护坡喷播基材中的生长数量特征和适应性指标进行统计分析。选取主要评价指标,建立边坡植物适应性评价体系,运用层次分析法确定权重,对研究对象进行适应性评价。主要结论如下:1、供试植物的发芽能力依次为:景天>萱草>苜蓿>黑麦草>白三叶>结缕草>高羊茅;在一个生长周期内的绿期长短顺序为:景天>高羊茅>黑麦草>苜蓿>萱草>白三叶>结缕草。2、夏至(6月21日)时苜蓿的地上生物量平均值显著高于其它植物,其次为高羊茅和白三叶,而结缕草、景天和萱草之间则差异不显著,且它们的生物量值远小于其它三种植物;秋分(9月23日)时苜蓿地上生物量平均值显著高于其它植物。从夏至到秋分,结缕草单位面积地上生物量横向增加量最大,白三叶最少。夏至时高羊茅、苜蓿、萱草的地下生物量显著高于其他植物;秋分时萱草的地下生物量显著高于其它植物,其次为高羊茅和苜蓿;到秋分时,各供试植物地下生物量较夏至时均有较大增幅。3抗旱性能力为:景天>结缕草>高羊茅>萱草>苜蓿>黑麦草>白三叶。4、供试植物在相同覆盖度下的抗雨水冲刷能力顺序为:结缕草>白三叶>景天>黑麦草>高羊茅>苜蓿>萱草。5、选取出苗率、抗旱性、覆盖速度、越冬性、地上生物量、使用年限、地下生物量、景观效果、绿期、主根长、建设成本、养护成本等十二个重要指标,构建边坡植物适应性评价体系,对供试植物进行适应性评价和质量等级划分,结果为:结缕草得分最高,综合分值约7.6,质量等级良。可大量的单播或混播应用;质量等级为一般的有苜蓿、高羊茅、景天和萱草;可根据他们不同特性结合工程实际进行有选择的应用;黑麦草得分小于6分,质量等级为差;白三叶得分最低,质量等级为极差。黑麦草和白三叶在专用护坡基材进行边坡防护中是不能作为保留种大量应用,可利用它们成坪快的特点作为先锋植物进行应用。更多还原

【Abstract】 The ecology compatibility of plants used in green slope is directly related to the display of landscape function and ecology function of virescence projects, which is an important attribute of restoring the side slope ecosystem and improving ecological environment. Taking Festuca arundinace, Medicago sativa, Zoysia japonica, Lolium perenne, Trifolium repens, Sedum spurium and Hemerocallis fuava as the research objects, the growth characteristic, drought resistance and anti-rain wash ability of the senen ground covers were studied in the special base material of green slope. Choosing the main evaluating indexes and establishing the compatibility evaluation system of side slope plants, the compatibility evaluation of the plants was carried on with analytic hierarchy process determining weight. The results were as follow:Firstly, the germinative capacity of the seven plant was as follows: Sedum spurium‘Coccineum’> Hemerocallis fuava> Medicago sativa> Lolium perenne> Trifolium repens> Zoysia japonica> Festuca arundinacea. The length of green time in a vegetative cycle was as follows: Sedum spurium‘Coccineum’> Festuca arundinacea> Lolium perenne> Medicago sativa> Hemerocallis fuava> Trifolium repens > Zoysia japonica.Secondly, the average aboveground biomass of Medicago sativa on summer solstice (June 21st) was particularly higher than other plants, and the following was that of Festuca arundinacea and Trifolium repens. But there was no significant diference between Zoysia japonica, Sedum spurium‘Coccineum’, Hemerocallis fuava, and their average aboveground biomass was far lower than that of the other three. On autumnal equinox (September 23rd), the average aboveground biomass of Medicago sativa was particularly higher than other plants, and the following was that of Festuca arundinacea and Zoysia japonica.During the time from summer solstice to autumnal equinox, the transverse increase of aboveground biomass in unit area of Zoysia japonica was the most,while that of Trifolium repens was the least. On summer solstice, the underground biomass of Festuca arundinacea, Medicago sativa, Hemerocallis fuava was significantly higher than other plants. On autumnal equinox, the underground biomass of Hemerocallis fuava was significantly higher than other plants, and the following was that of Festuca arundinacea and Medicago sativa. Compared with the time of summer solstice, the underground biomass of the seven plants had great increase than on autumnal equinox.Thirdly, the drought resistance was as follows: Sedum spurium‘Coccineum’> Zoysia japonica > Festuca arundinacea > Hemerocallis fuava> Medicago sativa > Lolium perenne > Trifolium repens.Fourthly, the anti-rain wash ability under the same degree of coverage was as follows: Zoysia japonica> Trifolium repens> Sedum spurium‘Coccineum’> Lolium perenne > Festuca arundinacea> Medicago sativa > Hemerocallis fuava.Fifth, taking plant emergence rate, drought resistance, cover speed, winter hardiness,ground biomass,underground biomass, ages, landscape effect, green time, construction cost and maintenance cost as variables, compatibility evaluation system of side slope plants was established, through which the adaptability evaluation and quality grades division of the seven ground covers were carried on. The results suggested that the quality grade of Zoysia japonica was good with the highest score of 7.6, while that of Medicago sativa, Festuca arundinacea, Sedum spurium‘Coccineum’and Hemerocallis fuava was moderate. However, the quality grade of Trifolium repens was worst with the lowest score.更多还原
