人类干扰对甘肃麻家寺保护站鸟类群落的影响

Effects of Human Disturbances on The Bird Communities in Majiasi Station,Gansu

2004年11月～2005年1月，在兴隆山麻家寺保护站的6种生境（灌木、阔叶林、混交林、针叶林、农田和人工林）中共记录鸟类25种。鸟类物种总数以灌丛和人工林最高，均为15种。阔叶林最低，为10种。鸟类多样性最高的是灌丛，最低的是阔叶林。各种生境中的鸟类组成和优势物种差异较大，建议每种生境均保持一定面积，以便保护鸟类物种多样性。

The bird communities in six habitats （Shrub, Deciduous forest, Mixed forest, Coniferous forest, Cropland and Plantation） were surveyed in Majiasi Station of Xinglongshan from November in 2004 to January in 2005. A total of 25 bird species were recorded. The number of bird species was highest in the shrub and plantation （15 species） and lowest in deciduous forest （10 species）. The diversity index was highest in shrub and lowest in deciduous forest. There were big differences in bird species composition and dominant species in different habitats. So from a conservation point of view, every habitat in the nature reserve should have some area so as to protect bird diversity in this area by the protection of all forest types.
