江苏盐城湿地珍禽国家级自然保护区资源开发的阈值管理

Threshold Management of Resource Exploitation of the Yancheng Wetland Nature Reserve

通过分析主要保护对象丹顶鹤的越冬需求和资源开发活动对丹顶鹤及其生境的干扰,提出了针对保护区资源开发的阈值管理技术。设置允许适度开发、限制开发和禁止开发3种准入类型;准入区域限定在实验区内,面积应小于保护区总面积的1/10,且不大于实验区面积的1/3;准入时间上,根据丹顶鹤的越冬需求,确定每年9月末至次年2月末为限制利用期,3月初至次年9月末为适度利用期;停止新的滩涂围垦和风力发电项目建设,大力发展生态旅游。

The Yancheng Wetland Nature Reserve has to be confronted with the conflict between resource conservation and exploitation in its management and construction.Threshold management technologies of resource exploitation have been brought forward based on analysis of the needs of overwintering Grus japonensis and disturbance caused by resource exploitation.For access into the reserve,resource exploitations are sorted into three types： moderate exploitation,restricted exploitation and forbidden exploitation.The area accessible for exploitation is limited to the experimental zone,which should be kept no more than 1/10 of the nature reserve,and should not exceed 1/3 of the experimental zone in area.Based on the birds′ needs for overwintering,the time period of a year from the end of September till February of next year should be set as restricted for exploitation activities and from early March till the end of September as accessible for moderate exploitation.It is acceptable to go all out to develop ecotourism,while it is essential to ban any new project of tide flat wetland reclamation and wind energy in the reserve.
