流沙固定 meaning in English
fixation of shifting sand
Examples
- By analyzing on nature , society and economy conditions as well as distribution characteristics of sand source in the lower lhasa river valley , put forward a series of comprehensive renovation scheme to harness sand sources , mainly including dredging channel , planting farmland shelter - forest network , constructing arbor - bush - herb shelter forest and shifting sand stabilization , this scheme will not only control blown - sand threat , and improve local ecological environment ; at the same time , also lay the strong foundation for enlarging lhasa city space and effectively utilizing local resource , embody a sustainable thought on how to make comprehensive renovation in high cold valley region
摘要在深入分析本区自然社会经济条件和风沙源分布特征基础上，提出把拉萨河下游河道疏浚与风沙源治理相结合，以河道疏浚、农田防护林、乔灌草防风护沙林和流沙固定等物理工程、生物和机械措施为主体，进行风沙源综合整治，一方面可有效控制风沙灾害的威胁，改善河谷区生态环境，同时为拉萨市城市空间发展和当地资源的有效利用奠定了基础，体现了在高寒河谷区进行风沙源综合整治的可持续性思路。 - The results show that compared to salix psammophila barrier , ecomat cover does decrease surface sand transportation rate ( sstr ) , increase surface soil nutrient , and enhance growth of platycladus orientalia to the extent , undoubtedly ecomat is one of surface cover materials for sand - fixation and revegetation ; compared to two other ecomat part - cover types ( banded and chessboard ) , the all - cover type can also decrease sstr , increase surface soil nutrient significantly , growth condition of platycladus orientalia , however , is not good as expected , which may attributes to lower infiltration rate of slight rainfall ; as for two part - cover types , chessboard type is better than banded type in increasing of sstr and enhancement of platycladus orientalia growth
研究结果表明，与沙柳沙障相比，生态垫确实可以降低近地表的输沙率，提高生态垫下土壤的养分含量，一定程度上提高柠条的地径和高度，可见生态垫是一种很好的促进流沙固定和植被恢复的地表覆盖材料；与其它两种生态垫铺设方式（品字状和带状）相比，全铺可以显著降低近地表的输沙率，提高其下土壤的养分含量，但柠条的生长状况却略差，这可能与全铺降低了小雨入渗的可能性有关；就两种部分铺设的方式而言，无论从降低近地表的输沙率还是促进柠条的生长土来看，品字状都明显优于带状。
