摘　　要：河南省南阳市既是南水北调中线工程重要的水源地，也是工程渠首所在地，其生态地位非常重要。在分析影响区域生态环境敏感性和生态系统功能重要性的主要指标基础上，采用定性分析和定量评价方法相结合，进行了水源区生态环境敏感性和生态功能重要性研究。结果表明：研究区属土壤侵蚀中度敏感区；区域的南部丹江口水库库体周围和丹江支流水体周围是重要的水源涵养区，北部山区是重要的生物多样性保护区，库区周围的低山丘陵区是重要的土壤保持区。提出了在生物多样性功能区，禁止滥砍滥伐林木和人为捕猎野生动物；在丹江口水库水源涵养区，要栽植水源涵养林，发展生态农业，控制工业、生活和面源污染；在丹江口库区及周围的浅山丘陵区（土壤保持区），要控制区内植被破坏，退耕还林、还草。As the important water source area of the south to north water transfer project and the canal head location, the ecological status of the Nanyang City in Henna Province is very important. This article reports the assessment of eco-environment sensitivity and eco-function importance in the water source area by means of methods of qualitative and quantitative analysis on the base of the index analyses influencing upon eco-environment sensitivity and ecological function importance. The result showed that the research area is moderate sensitive to soil corrosion. Southern part covering Danjiangkou Reservoir and its anabranches is the important headwaters; northern part is an important protection section of biology diversity;the hills around Danjiangkou Reservoir are the important soil maintenance area. It is also suggestted that, first, excessive cutting of forest tree and hunting must be forbidden in function areas of biology diversity, second, planting water-conserved forests, developing ecological agriculture and controlling pollution of industry, agriculture and surface source pollution must be done in water source conservation areas, at last, it is necessary to protect vegetation and return grain plots to forestry or grass in soil maintenance area.
