旅游开发对丹霞山植被的影响研究

THE IMPACT OF TOURIST DEVELOPMENT ON THE VEGETATION COVER OF MOUNT DANXIA, GUANGDONG

本文从植被生态环境质量和景色质量管理的角度，以群落景观重要值、旅游影响系数、敏感水平等定量分析为依据，初步研究了旅游开发对丹霞山植被产生的影响，并提出了几点植被管理对策。

The impact of tourist development on the environment quality of the vegetation ecology and the quality of scenery management of Mount Danxia in Shaoguan, Guangdong is quantitatively analyzed in terms of the value of landscape, tourist impact coefficient and sensitivity level. The perpendicular profiles of five scenic vegetation plots were selected in the tourist area to demonstrate and analyze the visual aesthetics of the scenery. Twenty two sampling quadrats were selected to reveal the impact of tourist development on the vegetation cover, of which ten are tourist areas. Several conclusions were reached. First, there was a 20% decrease of vegetation in the heavily visited tourist areas. Second, while the vegetation in tourist areas is protected, 30%￣70% of the vegetation in non tourist areas has been destroyed. Third, the old trees near tourist spots have suffered from termite destruction and withered as a result of weakened resistance, whereas the trees some distance away from tourist areas were often felled by hotels and temples for fuel. Generally speaking, however, tourist development in Mount Danxia has stabilized the plant groups' ecological environment.
