| 中文摘要: |
| 根据滇西北老君山的区域特征,选取高程、坡度、坡向、河流缓冲区、土地利用类型、植被覆盖指数6 个因子,利用层次分析法确定因子权重,在GIS 中按各因子的权重进行叠加分析,得出滇西北老君山生态敏感性综合分布图,对生态敏感度进行定量分析。结果表明,在研究区的5 个生态敏感性等级中,不敏感、低度敏感、中度敏感、高度敏感、极度敏感区分别占研究区总面积的7.87%、15.72%、23.66%、35.44%、17.31%,中度和高度敏感区面积占59.10%,表明滇西北老君山生态敏
感性程度较高,生态脆弱而敏感。在今后的保护与利用规划中,应结合生态敏感程度统筹规划保护和发展项目,建立健全有效的生态保护体系,实现区域生态保护与利用协调发展。 |
| 英文摘要: |
| Based on the regional characteristics of Laojun Mountain in northwest Yunnan, six factors of
elevation, slope, slope direction, river buffer zone, land use type, and vegetation cover index were selected.
The weight of each factor was determined using the analytic hierarchy process. Superposition analysis
was then conducted in GIS according to these weights to generate a comprehensive ecological sensitivity
distribution map of Laojun Mountain, enabling a quantitative assessment of its ecological sensitivity.
The results showed that among the five ecological sensitivity levels identified in the study area, the
non-sensitive, low-sensitive, moderately sensitive, highly sensitive, and extremely sensitive areas accounted
for 7.87%, 15.72%, 23.66%, 35.44%, and 17.31% of the total study area, respectively.
The combined area of moderately and highly sensitive areas comprised 59.10% of the total, suggesting a
generally high level of ecological sensitivity and fragility in Laojun Mountain. In the future protection and utilization planning, the degree of ecological sensitivity should be combined with the integrated planning of
protection and development projects, the establishment of a sound and effective ecological protection system,
and the realization of the coordinated development of regional ecological protection and utilization. |
