摘要
进入21世纪以来,我国草地蝗灾连年发生,严重威胁着畜牧业发展和北方生态安全。经济阈值和生态阈值作为蝗虫防治的决策依据,是草地植保领域的重要研究课题之一。对国内外有关害虫防治经济阈值和生态阈值的概念及理论进行了概述整理,全面总结了我国在草地蝗虫防治经济阈值与生态阈值方面的研究进展,分析了2个阈值在实际应用中的关系。目前,本领域研究缺乏系统性和持续性,难以有效指导草地上复杂的蝗虫灾变形势,为此对今后的研究提出了几点建议。
Since the 21st century,grassland locust plague has occurred successive years in China,which has threatened animal husbandry development and north ecological security seriously.The study on the economic and the ecological threshold which offers the decision basis for locust control is one of the important research subjects in grassland plant protection field.The concept and theory of economic and ecological threshold for pest control were reviewed and discussed.The research progress on economic and ecological threshold of locust control and the relation of two thresholds in practical application in China was summarized and analyzed.At present,lacks of the systematic and sustained research in this area lead to ineffective direction about the complex situation of locust plague in China.Therefore,some suggestions were put forward for the future research.
