盐城越冬丹顶鹤栖息地保护与经济发展之间的关系

江苏盐城国家级自然保护区丹项鹤越冬数量已由建区前的230只增加到2000年春的1128只，但近几年分布数量呈下降趋势，2008年1月仅有640只。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，另有部分群体继续向异地迁移的可能。各种类型的工农业开发项目导致栖息地大范围缩小，生境破碎化，是盐城越冬丹顶鹤种群数量下降的主要原因。根据该地区滩涂自然规律，在保护区核心区外允许开发的区域规划和实施人工湿地生态经济系统，协调保护与开发之间的矛盾，实现栖息地保护与经济发展双赢的目标。

Relationship between Protection and Economic Development of Wintering Habitat of Red-crowned Crane in Yancheng

In Yancheng National nature reserve, number of wintering red - crowned crane increased from 230 at the beginning of the reserve to 1 128 at 2000, but in recent years, gradually decreased to 640 individuals in January, 2008.Yet, in the central region of the habitat, number of birds still maintained stable and with a trend to increase in the future, while a part of the population may migrate to other habitats. The main reason was the reduction of the habitat area and its fragmentation due to different forms of development in industry and agriculture. According to the natural development of the sea beach, establishment of artificial wetland economic system was permitted so that conservation of the red - crowned crane and development may be harmonized, in order to gain the double win of habitat protection and economic development.
