旅游干扰对嵖岈山景区生态影响研究

Ecological Effects of Tourist Disturbance in the Rural Tourism Testination of Chaya Mountain Scenic Area

  • 摘要: 通过比较距离游径0、5、10、20 m处样方内土壤质量和植物群落特征变化情况,研究了旅游干扰对嵖岈山景区生态环境的影响.结果表明:旅游干扰显著提高了游径10 m内的土壤pH值和游径边缘的土壤容重,显著地降低了游径5 m内的有机质水平,并总体上降低了游径周边10 m内土壤全氮含量.旅游干扰显著降低了游径附近5 m内的灌丛盖度,并且减少了游径边缘的乔木幼苗数量.旅游干扰降低了草本植物高度,这种影响主要集中在游径边缘5 m以内.而对草本植物多样性的变化在不同土壤带上表现不一,在较高海拔区域旅游干扰显著增加了游径边缘的草本多样性.但在低海拔区域,旅游干扰给草本植物多样性带来的影响较小.

     

    Abstract: The influence of tourist disturbance on plant communities and soil properties in Chaya Mountain scenic area is assessed through comparing the conditions among the different distances of 0,5,10,20 m away from the tourist trail where the intensities of tourist disturbance are distinct.The results are as follows:the tourist disturbance significantly increases the soil pH within 10 m in diameter from the trail and increases the soil bulk density on the edge of the trail.However,the tourist disturbance significantly reduces soil organic matter and total nitrogen content within 5 m in diameter from the trail.The tourist disturbance significantly decreases the amount of the tree seedlings on the edge of the trails and significantly decreases the shrub cover in the nearby 5 m in diameter from the trail.The negative impact of the tourist disturbance on heights of herbaceous plants are mainly concentrated in the region within 5 m in diameter from the trail,and the changes of herbaceous plant diversity differs in different regions,and in the high altitude area tourist disturbance significantly increases the herbaceous plant diversity on the edge of the trail.But in the low altitude region,the influence of the tourist disturbance to the diversity of herbaceous plants is smaller.
