【摘要】 桑干河在山西境内的河流长度为252公里,由上游源河、恢河在马邑汇合后经朔州市、大同市,至阳高县尉家小堡村进入河北省。桑干河流域周缘自然环境复杂多样,区域内的晋北防护林是“三北防护林”的重要组成部分,承担着“京津风沙源治理工程”的重要角色。中华鼢鼠(Myospalax fontanieri)是桑干河流域内危害最严重的鼠害种群,因而掌握中华鼢鼠的生活习性,了解其对植被的危害程度及危害规律,是鼠害预警监测和制定有效防控措施的前提。对中华鼢鼠进行综合防控,不仅可以有效降低鼠害危害,提高苗木成活率,促进森林植被的恢复,还可以提高防护林防风固沙的能力,有效减少水土流失、改善生态环境,使桑干河流域森林资源得到保护,从而丰富该地区的生物多样性,对于促进森林健康、建设人与自然和谐共存、维护生态系统稳衡及生态安全具有重大意义。通过对桑干河流域防护林中华鼢鼠鼠害情况的实地调查,将收集的数据与信息进行科学分析后,明确了桑干河流域内中华鼢鼠发生特点、为害程度、危害区域划分以及综合防控措施,并结合该区域的地类、植被等特征,提出了防控中华鼢的综防措施及对策建议,为未来鼠害防治工作提供了参考。更多还原

【Abstract】 Sanggan River runs for 252 kilometers in Shanxi Province,which was converged by two upstream rivers(Yuan River and Hui River)in Mayi.Then,it flows through Shuozhou District,and Datong District,and flows into Hebei Province at the YuJiaXiaoBu,Yanggao County.The natural environment of the Sanggan River Basin is complex and varied,and the Jinbei Shelter Forest in this region is an important part of "the northwest-north-northeast China networks of Shelterbelts",which bears the important role of"Beijing-Tianjin wind and sand source control project"Chinese zokor(Myospalax fontanieri)is the most harmful rodent population in the Sanggan River Basin.Therefore,understand the life habits,damage degree and occurrence rule is a prerequisite for early warning and monitoring of rodent damage and formulating effective prevention and control measures to Chinese zokor.From an ecological point of view,the implementation of integrated prevention and control of zokor not only effectively reduce rodent pests,improve the survival rate of seedlings,promote the restoration of forest vegetation,but also improve the windbreak,and sand fixation abilities of shelter forest,which effectively reduce soil erosion,improve the ecological environment and protect forest resources in the Sanggan River Basin.Thus enriching the biodiversity of the region is of great significance for promoting forest health,building harmonious coexistence between man and nature,maintaining ecosystem stability and ecological securityAfter analyzing the data collected through field investigation of the damage condition of Chinese zokor in shelter forest of Sanggan River Basin,the Chinese zokor occurrence,damage degree,damage regional division,and integrated prevention and control system were clarified.In accordance with the soil and vegetation characteristics of this region,the integrated prevention and control measures of Chinese zokor was proposed,which provides reference for the prevention and control of rodent damage in the future.更多还原
