我国风沙防治工程研究现状及发展趋势

The Research Status and Development Trends of Wind-Sand Engineering in China

对风沙工程学概念和范畴进行了讨论,初步回顾了我国风沙工程学的发展过程。根据区域环境特征将我国风沙工程研究分为基于沙漠环境的重大工程风沙危害防治研究和其他特征环境区重大工程风沙危害防治研究2个部分。其中,基于沙漠环境的重大工程风沙危害防治研究又可划分为4个阶段,其他特征环境重大工程的风沙危害防治研究主要集中在热带海岸、青藏高原及干旱区戈壁等区域。研究认为,我国重大风沙防治工程的发展趋势可概括为:(1)风沙工程防治体系原理的揭示;(2)重大风沙工程环境效应评价;(3)防沙工程从单纯防沙功能向经济生态型防护体系转变;(4)防沙材料装配式和施工工艺装备化的高效率、高质量快速治理技术。

The concept and category of wind-sand engineering were discussed in this paper.The development processes of wind-sand engineering in China were reviewed preliminarily.Based on different regional environments,wind-sand engineering research in our country can be divided into two parts:aeolian research of major engineering in desert areas,and aeolian research of major engineering in other areas with special environment.Further than that,aeolian research of major engineering in desert areas can be divided into 4 stages,and aeolian research of major engineering in other areas with special environment mainly focuses on tropical coastal areas,Tibet Plateau and gobi in arid areas.Our research suggests that the development trends of major wind-sand engineering can be summarized as the following aspects.(1)Revealing principles of the windsand engineering shelter systems;(2)Evaluating environmental effects of the major wind-sand engineering;(3)Functions of the wind-sand engineering transforming from simple sand prevention to eco-economic types shelter systems;(4)A kind of treatment technology with fabricated materials and equipped construction processes needs to be studied urgently,which can make sand prevention with rapid pace,high efficiency and high quality.
