Study On The Woodland Rodent Communities With Reference To Diversity And Damage Control In Zhangjiakou District

Zhangjiakou district, Hebei province, is the main area to prevent and control mobile sand source adjacent to Beijing and Tianjin. However, recently with the great improvement in planting there, rodent damages come to be becoming the crucial point. This study is aiming to determine the woodland rodent species, community type and present status in damage in three typical counties along highland, Zhangjiakou district, Hebei province, so as to set scientific base for rodent pest control. The results are presented as follows.1. Woodland rodent species and distribution in highland Zhangjiakou district were investigated in the study. Out of a total species of 17 rodents captured, from 11 genera, 4family. All of them belong to Paleo-arctic species, 41.2% of them is components of Mongolia-Xinjiang region, 52.9% is that of North-East China region, and 5.9% is others.2. 6 rodent community types were distinguished with cluster analysis in studied woodland on the basis of rodent species of each habitat. And the preliminary analysis of these communities shows that community diversity index are related to faunal component, habitat complex and mankind activity.3. Survey of rodent damage in woodland indicated damage mainly occurred to reforestation and young plantation but not to mature plantation and natural forest.4. Detailed studies of Zokor on its food habit, habitat preference and damage ways showed that soft and moist soils with abundance food are Zokor's favorite factors. Grass is their major food resources but trees thus Zokor have no damage on trees.5. We documented characteristics of woodland rodent damage in Zhangjiakou district and this allows us to consider the measures to prevent and control damage. And its relative principal and approaches may adoptable in Zhangjiakou district as well.
