塔里木河下游输水工程生态变化的量化研究及价值评估

Abstract:Due to the core issues,such as the response value of surface ecology and the assessment of potential recovery value,in ecological water transport,which is a major ecological restoration project in the lower reaches of Tarim river,we take the quantify and assessment of the ecological changes in ecological water transport engineering as the main content.We quote the theories and methods from domestic and foreign to research the interactive relationship between river and ecology in arid zone,then analysis the changes and processes of surface ecological response due to the differences in degradation extents and water conditions in different reaches of river.Based on the long-term monitoring data,we quantify the ecological processes of different kinds of vegetations such as Joe、irrigation、grass and estimate the function and value of its services.Our research focus on the ecological functions and their potential value of services of the ecological and environmental factors which have great significances for ecological restoration.By comparing the service value and potential recovery value of the surface ecological response on different reaches,we analysis the value targets of water resources from different water supply modes,assess the benefits of ecological restoration that take the reach as a unit,investigate the interaction mechanisms and the coupling relationship among water、ecology、economic value through the water transfer process.From the aspects of rational utilization of water resources and ecological environment sustainable,we evaluate the changes and its benefits in ecological water transport engineering on the lower reaches of Tarim river.Through this study,we can provide some theoretical basis and technical support to the ecological comprehensive management in Tarim river basin.

针对塔里木河下游生态输水这一重大生态恢复工程评价中的地表生态响应价值和潜在恢复价值评估等核心问题，选择生态输水工程生态变化的量化和评估为主要研究内容，借鉴国内外相关理论和方法，研究干旱区内陆河生态输水后的恢复效益，分析不同河段因退化程度和过水条件差异造成的地表生态响应变化及其过程，基于长期监测资料量化不同乔、灌、草的生态变化，估算其服务功能及价值；重点分析对于生态恢复意义重大的生态和环境因子的生态功能及其潜在服务价值；对比不同河段地表生态响应差异的基础上，研究不同给水方式下水资源的价值流向，评估以河段为单元的生态恢复效益，探讨输水过程中水、生态、经济价值之间的互动机制和耦合关系，从水资源合理利用和生态环境可持续发展的角度，综合评价塔里木河下游生态输水工程中的生态变化及其效益，为塔里木河流域生态综合治理提供理论依据和技术支撑。
