青藏高原快速城市化地区生态服务价值影响评价——以西宁市为例

Impact Assessment of Ecological Service Value in the Rapid Urbanization Areas of Qinghai-Tibet Plateau:A Case Study of Xining

青藏高原是地球生态环境演变中的重要支撑,因其特殊的生态地位使人类活动的影响明显的小于其他区域,而脆弱的生态环境决定了人类的任何扰动都可能使其受到巨大的影响。本文以西宁市为例,将城市化作用下不同时段生态系统服务价值进行综合评价,其结果:反映了市域整体生态环境服务价值趋于动态变化,不同土地利用类型间差异性变化明显,并表现出西宁市经济与环境协调性仍处于低水平发展状态。

Qinghai-Tibet Plateau is a crucial support for the evolution of earth's ecological environment. Thanks to the special ecological status of Qinghai-Tibet Plateau,human beings' activities have been less affected than other areas. Because of the weakness of ecological environment,whatever human beings' disturbance will have a huge impact on the ecological environment. Based on the study of Xining,this research makes a comprehensive assessment on different times of the ecological service value under the role of urbanization. The results show that the ecological service value of city region is dynamic development. The difference is obvious among different land-use type. Furthermore,the coordination between economy and environment is at low level.
