大山包黑颈鹤对旅游干扰的行为反应研究

Dashanbao on Grusnigricollis behavioral responses to tourism disturbance

利用警戒距离和惊飞距离两个指标来反映黑颈鹤对旅游干扰的耐受性。实验表明人数的不同对黑颈鹤的惊飞距离有所不同。研究还表明游客的干扰类型以喧哗为主,占总数的73.10%。噪音分贝对黑颈鹤的警戒距离有极显著影响(p=0.000<0.05)。为了在提高游客旅游体验的同时,消除旅游活动对黑颈鹤的不利影响,建议最小接近区域面积=π×39.112=4802.92m2,该区域范围内限制游客进入,并在外围设立障碍物。

This paper mainly studies the Grusnigricollis′reaction to the tourism activities,the warning distance and flight distance of these two indicators to reflect the tolerance of black necked cranes to human disturbance.Experi-ments show that the number of black necked cranes flight distance is different.In addition,studies also show that the interference to noise types of visitors,accounting for 73.10% of the total.It has a very significant effect on the noise decibel black warning distance （p=0.000〈0.05 ）.In order to improve the tourist experience at the same time,and to eliminate the negative effects of tourism activities on the Grusnigricollis,it is recommended the mini-mum access area =π×39.112=4802.92m2,within which the number of visitors is limited,and the barriers be set up in the periphery.
