摘要:低覆盖度治沙理论是以疏林或稀疏灌丛植被格局的演变为内涵,外延出优化格局的风沙物理和生态水文原理与过程;组合了林学边行优势与生态学界面效益理论,形成的一套人工治理与自然修复有机结合的生态修复理论。该理论开创了植被在低覆盖度(15%-25%)下实现防沙治沙目标的新领域,显著提高了稀疏植被的阻风固沙和水分利用效率,提出了不同生物气候区低覆盖度治沙的控制密度和基本原则,支撑了2015年《国家造林技术规程》(旱区部分)的修订。低覆盖度治沙理论已成为指导我国防沙治沙工程的重要理论,引领了一个崭新的研究方向,有力地推进了防沙治沙事业的进步。
Connotation low coverage sand theory is the evolution of woodland or savanna shrub vegetation patterns. The theory of sand control with low coverage have include sand physics, hydrology, ecology and sustainable development. The most important thing is doing the repair and restoration of natural organic combination of ecological restoration theory. The theory opens up new areas of vegetation to achieve the goal to combat desertification at low coverage (15% -25% ). It support the most important amendment "National Afforestation Technical Specification" (Arid and Semiarid Zones) in 2015. Low coverage sand theory has become an important theo- retical guidance of anti - desertification projects, leading a new research direction.
