Abstract : based on the mechanism about herbage - squared - sand - obstacle for windbreak and sand - fixation , this paper propounded it ' s prognostication model , this model forecasted the sand - disaster of the daqi station on baoshen railway line 文摘:基于草方格沙障防风固沙机理,提出了沙害预测预报模型,该模型对包神铁路达旗车站沙害进行了预测预报
Enclosing sandy - land merely without sand barriers ca n ' t lead to effective restoration of its vegetation . and in such sandy - land , the dominant plant species is still agriophyllum arenarium , and the coverage and the species richness are rather low 只封禁多年但没有设置沙障的流动沙丘,其植物群落的恢复效果很差,优势种依然为沙米,并且群落盖度和物种丰富度很低。
Organic matter , total nitrogen , total phosphorus and total potassium content was higher than barren sand , increasing by 1 . 78 , 1 . 97 , 1 . 64 , 1 . 14 times , it showed salix psammophila checkerboard improved fertility condition of soil 设置沙柳沙障后沙丘土壤有机质含量是对照地的1 . 78倍,全氮含量是对照地的1 . 97倍,全磷含量是对照地的1 . 64倍,全钾含量是对照地的1 . 14倍,说明设置沙柳沙障能够改善沙丘土壤的养分状况。
If mechanical and biological sand barriers are established in such land , sand can be prevented from drifting effectively , so that with the stabilizing of sand much more plant species can settle down easily , and the plant species richness can increase dramatically 强烈的风沙活动是流动沙地植物定居的限制因子。采取机械沙障和生物沙障的植被恢复重建措施,可以迅速固定流沙,促进植物的定居,提高植物物种丰富度。
In a wind - eroded region , such measures as exploitation of water resources , water diversion for sand removal , planting of trees and growing of grass , installation of artificial sand - break and forest network shall be adopted to build a protective system for windbreak and sand - fixation , thereby controlling hazards of sand storms 在风力侵蚀地区,应当采取开发水源、引水拉沙、植树种草、设置人工沙障和网格林带等措施,建立防风固沙防护体系,控制风沙危害。
Compared with straw - barriers or wooden barriers , clay - barriers may well be in favor of the settlement of plant species at first , in the long run , however , they will hold back the development of leymus secalimus population , so that it will take much longer time for the plant community to restore to its climax stage 与草木沙障相比,粘土沙障设置初期可能有利于植物的定居;但是会对赖草种群的发育产生不良影响。所以,从长远看来,粘土沙障不利于沙地植物群落的恢复。
