摘  要：
2006年5—9月在广东省罗坑自然保护区,对大竹园管护站所辖区域内鳄蜥栖息溪沟的林型进行了调查,采用选择指数法研究了鳄蜥对溪沟林型的选择性。共调查了154只鳄蜥的生境特征,并对5种溪沟林型(常绿阔叶林、针阔混交林、针叶林、竹林和灌草)进行了样方调查。结果表明:鳄蜥对溪沟林型的选择是非随机的,偏好常绿阔叶林,对竹林接近于随机选择,回避其它林型;鳄蜥选择常绿阔叶林可能与其植被盖度较高、涵养水源能力强以及土壤有机质含量高有关。建议加强对常绿阔叶林的保护工作,以更好地保护鳄蜥。

摘  要：
From May to September,2006,an investigation was made on the forest type in mountain streams within the area under jurisdiction of Dazhuyuan protection station in the Luokeng Nature Reserve of Guangdong Province,where Shinisaurus crocodilurus inhabited,and the selection of S.crocodilurus on forest-type was studied with selection index method.The habitat characters of 154 S.crocodilurus individuals and the samples of 5 forest types(evergreen broadleaved forest,bamboo forest,mixed coniferous and broadleaved forest,coniferous forest,and shrub and grass)were surveyed,and the results showed that the selection of S.crocodilurus on forest type was not at random.S.crocodilurus preferred evergreen broadleaved forest,selected bamboo forest almost by chance,and kept away from other forest types.The selection on green broadleaved forest was probably due to the higher coverage of vegetation and the higher soil water-holding capacity and organic matter content.It was suggested that more attention should be paid on the protection of evergreen broadleaved forest to better protect S.crocodilurus.
