摘要
生态系统健康评价是区域生态系统管理的基础。以生态系统健康、景观生态学等理论为基础,建立了景观尺度的区域生态系统健康评价指标体系;利用GIS和RS技术,以1km×1km为单元格,评价了拉萨地区的生态健康状况。结果表明:拉萨地区生态系统很健康区域占3.76%,健康区域占5.79%,亚健康区域占33.27%,不健康区域占到28.80%,疾病区域占28.38%,拉萨地区生态系统健康堪忧。政府应采取相应措施对其进行有效的控制,人类活动强度必须视生态系统的健康状况而定。
The ecosystem health assessment is the foundation of regional ecosystem management.Based on ecosystem health and landscape ecology theories,we established an assessment system of ecosystem health on the landscape scale and assessed the ecosystem health status of Lhasa by using GIS and RS technologies.The result showed that the very health area accounts for 3.76% in Lhasa,health one is 5.79%,sub-health is 33.27%,unhealthy is 28.80%,and disease is 28.38%.The whole ecosystem health is worried in Lhasa.The government should take corresponding measures to control effectively.The human activity must be done according to the ecosystem health status.
