向海自然保护区芦苇湿地资源开发与丹顶鹤栖息地保护

向海自然保护区芦苇资源丰富,芦苇湿地又是丹顶鹤的重要繁殖栖息地,芦苇资源开发与丹顶鹤栖息地保护之间存在一定矛盾。2002年春季,向海湿地芦苇面积21 663hm2,芦苇总产量为13 700t,随着干旱的加剧,芦苇产量逐年降低;调查了丹顶鹤的迁徙动态及繁殖情况,探讨了芦苇资源的刈割方式对丹顶鹤的影响,不同的刈割方式对丹顶鹤繁殖的影响较大;提出了芦苇资源合理开发与丹顶鹤栖息地保护有机结合的对策。

The relationship of reed resources exploitation and the red-crowned crane breeding habitat conservation in Xianghai Nature Reserve

The reed resource is very abundant in Xianghai Nature Reserve. Reed wetland is very important breeding habitat of Red-crowned crane. The contradiction exits between the exploitation of reed resource and conservation of Red-crowned crane habitat. In the spring of 2002, we conducted a survey on status of reed resource and its use in Xianghai wetland. The area of reed wetland in Xianghai is 21663 hm2,and the output of reed is 13700t, with the deteriorate of drought, the output of reed decrease year by year. We also investigated the migratory dynamic and breeding condition of Red-crowned crane and discussed the effect of reed cutting on Red-crowned crane. The style of reed cutting has much effect on the breeding of Red-crowned crane. In the end, we provided the strategy of harmony between exploitation of the reed resource and conservation Red-crowned crane habitat.
