1) vegetation flammability
植被可燃性
2) Vegetation recovera bility
植被可恢复性
3) caustophytolith
可燃性植物岩
4) flexible vegetation
柔性植被
1.
Choosing PVC slice to simulate the flexible vegetation,the laboratory experiments were carried out in an open channel with submerged flexible vegetation,and 3D acoustic Doppler velocimeter(Micro ADV) was introduced to measure the local flow velocities and Reynolds stress.
采用PVC薄片对柔性植被进行了模拟,并用三维Micro ADV对淹没柔性植被恒定水流进行了实验测量,获得了水流纵向流速和Reynolds切应力的分布。
6) sustainable vegetation
可持续植被
1.
The comprehensive technology including objective community setting,modulation of competition between grasses and shrubs,combination of plant selection and mixture,and the assessment indices are summarized,and the sustainable vegetation development is outlined in the end.
针对我国公路边坡植被持续性效果不佳的问题,提出了边坡灌木化植被建植技术概念,从植被建植目标选择、草灌竞争调节机制、植物组合混播模式以及植被验收评价指标等几方面建立了边坡灌木化综合技术体系,最后对可持续植被的发展思路进行了展望。
补充资料:地带性植被
又称显域植被。分布在“显域地境”、能充分反映一个地区气候特点的植被类型。
显域地境系指排水良好、土壤机械组成适中的平地或坡地。与地带性因素相适应,地带性植被在地理分布上表现出明显的三维空间规律性:因气温的差异,在湿润的大陆东岸,从赤道向极地依次出现热带雨林、亚热带常绿阔叶林、温带夏绿阔叶林、寒温带针叶林、寒带冻原和极地荒漠,称为植被分布的纬度地带性;从沿海到内陆,因水分条件的不同,使植被类型在中纬度地区也出现了森林→草原→荒漠的更替,称为植被相性(经度地带性);从山麓到山顶,由于海拔的升高,出现大致与等高线平行并具有一定垂直幅度的植被带,其有规律的组合排列和顺序更迭,表现出垂直地带性。植被的垂直地带性与水平地带性(纬度地带性与经度地带性的统称)是通过基带相联系的。
