自2004年至2008年,在白鹤GEF项目的支持下,全国鸟类环志中心于每年5月在东北松嫩平原的4个国家级自然保护区,即黑龙江的扎龙国家级自然保护区、内蒙古的科尔沁国家级自然保护区、吉林的向海和莫莫格国家级自然保护区,开展了繁殖水鸟的地面调查.调查的目的在于了解各个保护区繁殖水鸟的分布和种群动态.丹顶鹤(Grus japonensis)是本调查活动的重要目标物种.通过5年的调查,了解到松嫩平原的扎龙保护区是目前丹顶鹤最为重要的繁殖地,逾90％的繁殖丹顶鹤种群分布在扎龙保护区,但种群数量变动较大,变动幅度介于112-275只之间.良好的芦苇(Phragmites australis)生境是丹顶鹤的繁殖种群保持稳定和增长的首要条件.通过给湿地供水可以缓解丹顶鹤繁殖栖息地的快速退化,但科学合理的供水机制是保证丹顶鹤繁殖成功的前提.

With the support of the UNEP/GEF Siberian Crane Wetland Project,a five-year field survey of breeding waterbirds was conducted in four nature reserves - Zhalong,Keerqin,Xianghai and Momoge National Nature Reserves in the Songnen Plain for the period from May 2004 to August 2008.The purpose of the survey was to improve our understanding of the distribution and populations of breeding waterbirds in this area.The Red-crowned Crane (Grus japonensis) was the most important target species.Our survey results confirm that the Zhalong wetland is the largest breeding ground for the Red-crowned cranes in the Songnen Plain.Over 90％ of the breeding birds were found in Zhalong,with numbers fluctuating from 112 to 275 over the years.Reed (Phragmites australis) is the most important plant species associated with breeding locations of this bird species.Water supply to the wetland can relieve pressure from deterioration of wetland habitats for the breeding of Red-crowned cranes.However,a sound scientific basis for the water supply mechanism is the key to better management of their habitat and a prerequisite for ensuring the breeding success of the Red-crowned Crane.
