摘要:
基于GIS技术，根据星云湖流域主要生态问题选取6个因子，采用多因子加权求和模型对星云湖流域生态敏感性及其空间分布进行了评价分析，并按生态敏感性评价值将研究区划分为高度敏感区、中度敏感区、低度敏感区和不敏感区4个等级。结果表明：研究区高度敏感、中度敏感、低度敏感和非敏感区域面积分别为104.08 km2，124.52 km2，102.78 km2，39.30 km2；中度及以上敏感区面积约为228.60 km2，占流域总面积的61.67%，生态敏感性总体较高，空间上主要分布在江城镇、星云湖及其湖滨和雄关乡等；建议将高度敏感区划定为生态保护区加以重点保护，中度敏感区划定为控制发展区，低度敏感区和非敏感区为适宜发展区。评价结果能较好地反映流域综合生态敏感性空间分布特征，可作为流域土地资源开发建设和环境规划与保护的依据，并为高原湖泊流域开展类似研究提供参考。
Abstract:
Geographical Information System(GIS), and multi factor weighted sum model were used to analyze the ecological sensitivity and its distribution by selecting regionally representative factors according to environmental background in Xingyun Lake Basin. Four classes of ecological sensitivity ranging from high to low were generated: high sensitivity zone, moderate sensitivity zone, low sensitivity zone and non-sensitivity zone. The results indicate that the area percentages of the four classes are 104.08 km2, 124.52 km2, 102.78 km2 and 39.30 km2, respectively. The area of high sensitive area and moderately sensitive area are 228.60 km2, accounting for 61.67% of the total area of the basin, which shows that ecological sensitivity in Xingyun Lake Basin is. The high ecological sensitivity mainly distributes in Jiangcheng town, Xiongguan township, Xingyun Lake and its rural area. It is suggested that the highly sensitive areas should be designated as the ecological protection areas, and the moderate sensitive areas should be defined as the control areas, the low sensitive areas and the non sensitive areas should be planned as the suitable development areas. The evaluation results can reflect the comprehensive ecological sensitivity of catchment characteristics, can be used in the area of land resources development and environmental construction, and provide the reference for similar topography of plateau lakes.
