基于生态风险评估的旅游目的地开发研究——以吉林省大布苏国家级自然保护区为例

Development of Tourist Destinations Based on Ecological Risk Assessment——Taking Jilin Dabusu National Nature Reserve for Example

吉林大布苏国家级自然保护区的主要生态风险源来自人类活动,该保护区目前以开展生态旅游为主。以吉林省大布苏国家级自然保护区为例,运用生态风险评估的一般方法系统分析影响其生态风险的因素,确定其主要生态风险源为干旱、盐碱化、水土流失和人类活动,其中人类活动造成的影响特别突出。将ArcGIS应用于生态风险的评价当中,结合2004—2011年土地利用类型变化,绘制综合生态风险等级分布图,提出针对性的旅游开发对策以降低该保护区面临的生态风险,实现吉林省大布苏国家级自然保护区的可持续发展。

The mainly ecological risk sources in Dabusu National Nature Reserve was human activities. This paper used the general method of ecological risk assessment, as Dabusu National Nature Reserve for example, analyzed the risk factors which affected the ecological system, the main risk sources were drought, salinity, soil and water loss and human activities, and then used software of AreGIS in ecological risk assessment, according to the changes of land use types of 2004-2011, drew the grade comprehensive ecological risk of figure. At last, targeted measures must be taken to reduce the ecological risk for the development of Dabusu National Nature Reserve.
