10种大庆地区野生草本地被植物生态效益评价

Ecosystem Performance Evaluation of 10 Wild Ground Cover Herbs in Daqing District

[目的]比较从大庆周边地区引种栽培的10种野生草本地被植物对生态环境的改善情况。[方法]分别测定野生草本地被植物的叶面积指数、日释氧固碳量、日蒸腾水量和吸热量,进行定量分析。[结果]10种野生草本地被植物中无论是叶面积指数,日释氧固碳量还是日蒸腾水量及吸热量,三七景天、细蔓委陵菜、鹅绒委陵菜三者数值都较高,排名前三。[结论]三七景天、细蔓委陵菜、鹅绒委陵菜的生态效益最高。

[Objective]To compare ecological environment improvement of 10 wild ground cover herbs which were introduced and cultivated from the surrounding areas of Daqing district. [Method] The leaf area indexes, fixed carbon storage of the daily oxygen release, daily transpiration water and caloric receptivity of these 10 wild ground cover herbs were measured. [Result] The experience datas of Sedum aizoon L., Potentilla reptans L. and Potentilla anserina L.were higher than others.[Conclusion]Sedum aizoon L., Potentilla reptans L. and Potentilla anserina L. had the highest ecosystem performance.
