摘要
林业有害生物长期以来对森林等林业资源造成危害。为了解广元市利州区近年来林业有害生物发生现状,为林业有害生物的防治提供依据,依托四川省“林业有害生物防治信息管理系统”数据,对广元市利州区2018-2022年每年监测的林业有害生物数据进行分析和总结,查明其发生状况和规律,提出适宜防控对策。结果显示,2018-2022年,广元市利州区有害生物发生面积6600~9533 hm^(2),虫害和病害均有,虫害多于病害,主要危害为云南松毛虫(Dendrolimus houi)和蜀柏毒蛾(Parocraer orienta),发生程度以轻度为主。总体来看,2018-2022年广元市利州区林地有害生物发生面积不大,程度较轻,需要继续改进监测方式和提升监测能力,综合运用各类防治手段,着力优化改善林分结构。
Forest pests have long been harmful to forests and other forest resources.This paper relied on the statistical data of Sichuan Province"Prevention and Control Information Management System for Forest Pests"to analyse the data of forest pests in the monitored woodlands of Lizhou District,Guangyuan City during 2018-2022.The current situation of forest pests in Lizhou District of Guangyuan City in recent five years were obtained,and efficient preventive and control strategies were suggested.The result showed that during 2018-2022,a certain area and scale of forest pests occurred in Lizhou District,Guangyuan City,with an area between 6600 hm^(2)and 9533.33 hm^(2),and both insect pests and diseases were detected,with insect pest occurring more frequently than diseases.Specifically,the main pest insects identified were Dendrolimus houi and Parocraer Zaorienia Chao,and the majority of occurrences are at a mild level.Overall,the occurrence of forest pests in monitored woodlands in Lizhou District,Guangyuan City,from 2018-2022 was not large in area and was not in severe degree.Further,it is necessary to continue to improve monitoring methods and capacity,to make comprehensive use of various prevention and control tools,and to focus on optimising and improving the structure of forest stands.
