甘肃中部地区森林鼠害分布及生态习性研究

害鼠是农林牧业的大敌,是森林动物的主要组成部分。搞清森林害鼠的种类、种群地理分布、区系组成、群落结构及生活习性等是开展有效防治的一项基础性工作。通过4年的研究,基本摸清了辖区内森林鼠害的种类、数量、地理分布及习性状况;划分出了3个主要危害区;确定了中华鼢鼠和达乌尔鼠兔为中部地区森林害鼠优势种;掌握了群落结构以及主要害鼠生态习性。为进一步研究有效的防治方法,指导生产和大面积防治提供了理论依据,对中部干旱半干旱地区森林保护具有十分重要的意义。

Study on Distribution and Ecological Habit of Rodents in Central Forest of Gansu

The rodent,the foridable enemy of agriculture forest and animal husbandry which is a major component of forest animals.Finding out the type of forest rodents,geographic distribution of populations,floristic composition,community structure and life habits is a basic work to carrying out effective prevention.Through 4 years of research,rodent species,quantity,geographical distribution and habit in administrative region were basically felt out;and 3 major hazard regions were divided into;meanwhile,Myospalax fontanieri and Ochotona daurica,dominant species of forests rodents in the central region which were identified;and the community structure and ecological habits mainly rodents were mastered.Therefore,not only provide a theoretical basis for further study of effective prevention methods and guiding production and control a large area,but also it has a great significance to forest conservation in the central arid and semiarid regions.
