辽河口湿地黑嘴鸥繁殖栖息地的动态变化、保存与恢复

The Dynamic Changes, Preservation and Restoration of Larus saundersi's Breeding Habitat in Liao Estuary Wetland

辽宁盘锦的辽河口湿地是目前世界上最大的黑嘴鸥繁殖栖息地。利用数据收集、现场踏勘、遥感解译和GIS地理空间分析的技术手段分析了1995年至今的黑嘴鸥繁殖栖息地选择变化;从食物因素、水分因素、筑巢地植被因素等方面探讨了黑嘴鸥繁殖栖息地功能适宜性的变化;用景观指数分析了黑嘴鸥繁殖栖息地的完整性变化。根据分析所得的黑嘴鸥繁殖栖息地适宜性等级评价选取黑嘴鸥繁殖栖息地恢复的关键区域,并讨论了关键区域内栖息地的恢复方法。

Liaohe wetland of Liaoning Province is the world＇s largest breeding habitat for Larus saundersi. This paper summarized the population and habitat selection changes, analyzed the breeding habitat selection and the connection between the landscape pattern changes from 1996 through the use of remote sensing and GIS geographic spatial analysis technology. Then this article discussed the function changes of breeding habitat suitability through food, water, and nesting vegetation factors. And the landscape index was used to analyze the integrity changes of the breeding habitat. It selected key areas of restoration habitat and provide related recovery method at the end.
