草地生态系统有害啮齿动物的生物防治

啮齿动物产生的危害是当今生态系统中常见的灾害之一，对其开展有效的防治是全球范围内一个重要问题。人类在控制和消灭有害啮齿动物方面做出了巨大的努力，但种种措施均有利有弊，很难兼顾高效、安全和环境等问题，因而迄今仍停留在应急防治和重复投资等被动层次上。基于此，本研究在查阅大量文献的基础上，就国内外草地生态系统中啮齿动物防治的现状、开展生物防治的主要措施、存在的主要问题进行了综述，以期为有害啮齿动物的防控提供有益参考。

A review on biological control of grassland ecosystem harmful rodents

The rodents damage is one of the worldwide disasters in grassland ecosystem nowadays. Therefore, its effective prevention and control is an important worldwide topic. Human have made strenuous efforts on controlling and eliminating the harmful rodents, but a variety of measures have both advantages and disadvantages. It was difficult to give considerations with high efficiency, safety and environmental friendly. Thus, it was failed to get rid of emergency control and still in repeated investment state. Based on these, to provide helpful references for grassland ecosystem rodents vontrol in our country, this study summarized przncipal measures of biological control, the current situation and the main existing problems of rodent damage prevention and control at home and abroad.
