化感作用在水土保持生物措施治理中的应用研究

Review on Allelopathy in the Application of Biological Measures of Soil and Water Conservation Management

植物的化感作用是植被以小分子有机物为媒介调控种间和种内关系的机制,近年在水土保持生物措施中得到研究和应用。综述国内外化感作用在水土保持生物措施中的研究进展和应用潜力,重点评述化感作用在林地连栽障碍问题中的重要性和解决路径以及化感作用在优化植被结构中的应用;提出基于化感品种和化感物质数据库无缝对接基础数据库形成林草措施方案专家系统的设想。化感作用的研究方法和实验设计上需要充分模拟或结合实际生境,综合其它重要生态因子,使研究结果更可信和具有解释力。

Plant allelopathy is a sort of regulation mechanism for interspecific and intraspecific relations of vegetations with small molecule organic media ,which increasingly took place in the researches and applications of biological measures for soil and water conservation .The research developments and applicated potentials of plant allelopathy on biological measures in the soil and water conservation were reviewed ,underlining the vital role allelopathy plays in soil degradations ,its resolution and ,the optimizations of structure of vegetations .An en-vision about grass measures expert system was developed based on allelopathic species and allelochemicals da -tabases as well as their seamless connections to some basic databases .Plant allelopathy can not be separated as single significant factor from complex ecological processes .Research methods and experimental designs should be simulated or combine with natural habitats sufficiently and consolidate other important ecological factors to make the results more credible and explanatory .
