准噶尔荒漠鼠类群落结构及其栖息环境

The Structure of the Desert Rodent Population in Dzungaria Basin and Adaptation to the Various Habitat

通过对新疆准噶尔盆地沙质荒漠鼠类群落结构的两次对比分析 ,力求探讨其群落变化趋势 ,结果表明鼠类群落结构是动态变化的 ,优势种的更替是普遍存在的。这种变化是随着微生境 ,气候 ,植被等因素的变化而进行有规律的变化。我们根据鼠群的种类组成及其结构状况 ,将其划分为四个不同的鼠类危害区 。

This paper tries to find the change tendency of rodent population through comparative analysis of the structure of desert rodent population in Dzungaria basin . The result shows the structure of the rodent population is dynamic and the substitute of dominant species is common .This change is regular with the change of micro-habitat、climate、vegetation and so on. We divided it into four harmful regions of rodents according to the composition of the rodent species and population structure and provided some necessary foundation for preventing and eliminating rodents .
