摘要:

重点讨论了在全球气候变暖的大背景下,农业病虫草鼠害加重和新的病虫草鼠出现也作为一种蠕变现象正在遭受气候变化的影响和冲击,其主要表现在农业有害生物(病、虫、草、鼠)地理分布范围扩大、越冬界限北移、农田害虫害鼠发育时间缩短、繁殖代数增加、种群增长率加快、发生提早、危害加重、病毒病增加、新病虫草鼠出现等等。

Abstract:

Under the background of the global warming,the plant disease,insects,weeds and rats,as a new Creeping Environmental
Problems(CEP)phenomenon,was pointed out in this paper.It is suffering potential impacts from atmospheric change day by day.
That is to say,the area of geographical distribution of plant pest(disease,insects,weedsandrats)is extending,the line of overwinter is migrating toward north,the time of devolopment shorten,the propagation per year is increasing,the ration of population
in creasing will speed up,the time of pest occurring earlier,the disaster is heavier than before,virus disease will increase,new plant
disease,insects,weeds and rats will appear and soon
