通过盐城沿海滩涂即盐城国家级自然保护区丹顶鹤越冬分布和数量调查,探讨了数量动态变化与湿地环境变迁间的关系.丹顶鹤在本区的越冬种群数量在1982年到2000年间曾有显著的增长,最多时达1 128只,但近几年种群数量呈下降趋势.分析表明近期丹顶鹤越冬种群数量下降与保护区湿地类型的变迁有关.对丹顶鹤种群动态分布分析认为,未来于本区越冬的丹顶鹤种群在核心区的栖息仍然保持稳定及增加趋势,另有部分群体也有继续向异地迁移的可能.

Investigation on the quantitative change of the wintering red-crowned crane population in natural reserve for rare birds of Yancheng coastal beach in Jiangsu and the correlations with the Wetland Environment Variance are discussed. The results show that the wintering red-crowned crane population have significant growth between 1982 to 2000, as high as 1128, Recently, population number is decreasing which is related to the wetland type changes. The wintering red-crowned crane population in the core area of Yancheng Natural Reserve will increasing stably and the only a few will migrate in the future.
