中文摘要：
生态系统评价是当前生态学研究中的一个热点和难点，它能够为区域生态系统健康检测、优良生态系统类型筛选、土地利用格局合理配置以及生态服务功能优化提供宝贵的参考和决策依据。论述了生态系统评价的相关内容、研究的尺度问题以及目前相配套的研究方法，分析了其中存在的诸多问题，简明指出了今后的工作重点和努力方向，并展望了生态系统评价的未来走向。认为今后综合性的生态系统评价以及与此相配套的评价方法需要得到大力加强和研发，同时生态系统评价应该和区域水土流失治理、生态安全和可持续发展等重大问题紧密结合。
英文摘要：
At present, ecosystem evaluation was one of the most hotspots and difficulties in the field of ecology. It was used for providing valuable decision - making recommendations on the examination of regional ecosystem health, selection of suitable ecosystem types, and adjustmem of land use pattern as well as optimization of eco - service abilities. In this study, the evaluation contents, questions of research scale and relevant methods were addressed. Problems in the ecosystem evaluation and keystones which should be enhanced in the future were also separately pointed out and analyzed. Furthermore, based on these efforts mentioned above, the furore tendency of ecosystem evaluation was forecasted. We considered that more attention should be paid on the efforts and exploitations of comprehensive ecosystem evaluation and correspondingly quantitative methods. Meanwhile, the unborn evaluation on ecosystem should be closely combined with momentous and key regional problems such as soil erosion control, ecological security, and sustainable development, etc.
