漳江口自然保护区鸻形目鸟类适宜生境变化及驱动机制分析

摘要

With Zhangjiang Estuary land-use map, the plover birds’ suitable habitat map was developed by RS and GIS, a series of selected landscape indices were calculated by Fragstats, and the changes of Zhangjiang Estuary plover birds’ suitability habitat were analyzed.The range of birds’ suitable habitat is keeping decreasing.In contrast, the sub-suitable and unsuita-ble habitat areas increase.There is an increased fragmentation and then tended to stay stable on the later period.The dense human activities are the main reasons resulting in significant changes of Zhangjiang Estuary plover birds’ habitats.%以漳江口自然保护区土地利用图为基础，运用遥感系统和地理信息系统得到3个时期鸻形目鸟类的适宜生境分布图，选取一系列景观指数，运用Fragstats软件进行计算，分析约20 a（1992-2010年）漳江口自然保护区鸻形目鸟类生境的动态变化及驱动机制。结果表明：适宜生境分布面积呈下降趋势，次适宜生境和不适宜生境分布面积表现出一定的上涨趋势；适宜生境和次适宜景观破碎程度加剧，但后期有一定缓和；漳江口自然保护区鸻形目鸟类生境变化主要驱动力是人类活动干扰的增加。
