摘要
为了解广西象州县农田丘陵地带的鸟类群落结构,利用样线法辅以样点法对其进行了研究。研究表明,此次调查到象州县农田丘陵地带鸟类有77种2680只,隶属于11目28科57属。在调查区域的5种鸟类生境中,其中灌木林丛和农田生境所占总比例为最多,占61.8%,鸟的种类和数量最多,是鸟类活动的主要生境。在5种不同生境中,本次调查生物多样性比较:农田 】灌木林丛 】森林地 】内陆水域 】乡村居民点,均匀度比较:农田 】灌木林丛 】森林地 】内陆水域 】乡村居民点。本次调查的象州县的农田丘陵地带地区其高度的空间异质性能为各种水鸟以及猛禽提供很好的生存栖息地。
A survey of the structure of bird community in farmland hilly areas of Xiangzhou County, Guangxi had been conducted by a method that combines sample line and sample point. 77 species of birds were recorded in the hilly region of Xiangzhou County, which belonged to 11 orders, 28 families, 57 genera, totaling 2680 birds. Among the five bird habitats in the investigated area, the total proportion of shrubs and cutting sites and farmland areas were the largest, accounting for 61.8%. The species richness was the highest, which was the main habitat for bird activities. The highest total Shannon-Wiener index and the highest evenness index were observed in farmland, followed by shrubs and cutting sites, woodland, water area and village. The high spatial heterogeneity of farmland hilly areas in Xiangzhou County provides a good habitat for all kinds of waterfowl and raptors.
