摘要
生物工程在山地灾害治理中具有悠久的历史和重要的作用,然而由于多种原因,其理论研究和应用技术却远落后于工程实践。根据生物工程的原理及其特点,对其在山地灾害治理中的应用和研究现状进行了剖析,存在的主要问题为:生物工程在山地灾害治理中的应用范围不确定,工程设计和效益评估的标准不完善,植物根系研究的手段和设备有待改进,植物根系的"定向培育"开展的研究工作很少,植物枯枝落叶层的防灾、减灾作用研究不全面等。提出了生物工程在山地灾害治理中的主要研究方向,以期为完善和发展生物工程在山地灾害治理中的理论研究和应用技术服务。
The bio-engineering has long history and important effects on the prevention of mountain hazards. But the theoretical research and application technology lagged behind. In this paper, some key problems are put forward based on principles and characteristics of bio-engineering: (1) the applied area of bio-engineering is not certain; (2) the criterions of design and evaluation of bio-engineering prevention are not perfect; (3) the measures and apparatuses of study on vegetable roots need to be improved; (4) the studies on directional growth of vegetable roots are very few; (5) the studies on effects of forest litter are limited. According to these problems, the corresponding research projects are put forward in order to develop the theory of bio-engineering in mountain hazards preventions.
