摘要
为筛选出不同海拔下边坡生态修复中的植物类型,以某风电场为试验基地,分别在低海拔(700 m)和高海拔(1000 m)边坡进行开沟直喷纤维微生物肥植物种子。木本植物类型包括马棘、多花木兰、银合欢、紫穗槐、刺槐、马尾松和湿地松(播种量均为5 g/m^(2))。种子喷播覆盖完毕后,定时多次随机调查不同植物类型的生长数量。结果表明,在高海拔开横沟处理的边坡上,生长状况较好的木本植物有马棘和刺槐。在低海拔开横沟处理的边坡上,生长状况较好的木本植物有马棘、刺槐和马尾松。综合试验区的生态环境和气候条件,在风电场生态修复过程中,低海拔边坡修复建议选择木本植物马棘、刺槐、马尾松,高海拔边坡修复建议选择木本植物马棘、刺槐。给出了契合木本植物生长的边坡生态恢复方案,以期为生态修复工程建设奠定基础。
In order to select botany types of slope ecological remediation in different altitudes,fiber microbial fertilizer plant seeds are furrowed and straightly sprayed at low(700 m)and high(1000 m)altitude through taking a wind farm as the test base.Ligneous plants includes Indigofera pseudotinctoria,Magnolia multiflora,Leucaena leucocephala,Amorpha fruticosa,Robinia pseudoacacia,Pinus massoniana and Pinus elliottii(seed quantities are all 5 g/m^(2)).After the spray and coverage of seeds,the amount of growth of different plant types is randomly investigated several times at regular intervals.The results show that Indigofera pseudotinctoria and Robinia pseudoacacia grow better in the slope of transverse furrow in high altitude;and Indigofera pseudotinctoria,Robinia pseudoacacia and Pinus massoniana grow better in the slope of transverse furrow in low altitude.Under the consideration of ecological environment and weather conditions of the test site,it is suggested to select Indigofera pseudotinctoria,Robinia pseudoacacia and Pinus massoniana can be selected in the slope of transverse furrow in low altitude;and Indigofera pseudotinctoria and Robinia pseudoacacia can be selected in the slope of transverse furrow in high altitude in ecological restoration of wind farm slope.The study proposes the slope ecological restoration scheme suitable for woody plant growth to provide basis for the ecological restoration.
