基于生态红线划定的祁连山生态保护性开发研究

运用祁连山地区的自然环境数据和社会经济数据,基于GIS平台、加权求和多指标运算模型,选取了30个指标,从生态弹性力、生态敏感性和社会经济影响力3个方面,构建了生态红线评价指标体系,对祁连山生态保护性开发进行研究分析。结果表明:生态红、黄、绿线区,分别占研究区面积的32%、40%、28%。生态红线区主要分布于祁连山的西南段、托来山以南、青海湖区及区内所有冰川分布地区,应实行最严格的管控;生态黄线区是祁连山分布面积最广的区域,主要集中在祁连山中、西段,湟水谷地的中游及乌鞘岭南部,应以修复生态环境和提供部分农产品为主;生态绿线区主要分布在疏勒南山以东地区,应保护优先,以提供生态产品为主,分区开展各具民族特色的生态旅游。

Research on the development of the ecological protection of the Qilian Mountains based on ecological redline

Using the natural environment and socio-economic data on the Qilian Mountains, China, we selected 30 indicators and constructed an ecological redline evaluation index system based on three key aspects:ecosystem resilience, ecological sensitivity, and socio-economic influence. This system was constructed based on a GIS platform and a weighted sum multi-index computing model, so that it was possible to investigate ecological protection developments in the Qilian Mountains. Results showed that the ecological redline, yellow line, and green line zones accounted for 32%, 40%, and 28% of the total zone, respectively. The ecological redline zone is mainly located in the southwestern part of the Qilian Mountains, southern Tuolai Mountains, Qinghai Lake, and regions covered by glaciers, where the strictest controls should be implemented by the government. The ecological yellow line zone, characterized by the largest distribution area, mainly occurs in the middle and west Qilian Mountains, the middle reaches of the Huangshui Valley, and the southern part of the Wushaoling Mountains, where ecological restoration and the impact of agricultural land should be given priority. The ecological green line zone is mainly dominated by the eastern part of the Shulenan Mountains, where protection should be given priority in terms of providing ecological products and developing ethical ecological tourism by the regional government.
