Preliminary Report on the Application Effect of the Intelligent Monitoring System for Forest and Grass Rodents in the Northern Desert of Urumqi
[Objective]Grassland rodents account for the largest proportion of grassland biological hazards,and the harm is also the most serious.At present,rodent monitoring is still mainly carried out manually.However,due to the large area of forest and grass,wide distribution,and limited monitoring time,it is difficult to grasp the rodent damage in grassland in time.This study provided a reference for effectively solving the problems of difficult prevention and control of biological disasters caused by grassland rodents,low intelligence,high prevention and control costs,and insignificant prevention and control effects.[Method]The Urumqi Landscape and Greening Engineering Quality Supervision Station(Urumqi Forest and Grass Seedling Station)combined with Beijing Jiarui Jicheng Technology Co.,Ltd.,carried out application research on forest and grass rodent intelligent monitoring system in the northern desert of Urumqi,and recorded rodent image,weight,activity rhythm and environmental information in real time.[Result]The results showed that a total of 1 014 harmful rodents were detected,belonging to 4 genera and 4 species in 1 family,namely,the Rhombomys opimus,the Phodopus roborovskii,Lasiopodomys brandtii,and the Meriones unguiculatus.Among them,the sand rat accounts for 85.79%,which is the main dominant population.Activities are more frequent in spring from March to April and autumn from September to October.Activities are more concentrated between 7:00 am and 21:00 pm—22:00 pm.The proportion of small hairy footed mice is 11.93%.They are more active in March in spring and October in autumn,and their activities are more concentrated at 23:00 at night.[Conclusion]This intelligent monitoring system realized automatic classification recognition,intelligent indicator measurement,and real-time dynamic monitoring,which can accurately monitor the species of harmful rodents and grasp their seasonal and diurnal density dynamic changes in real time.The dynamic change of rodent population was recorded and analyzed,a local rodent monitoring database has been preliminarily established,which is of great significance for improving the level of early warning and prevention of harmful biological disasters in China,and reducing the cost of monitoring and prevention.
