准确掌握景观动态变化信息对于促进可持续土地管理、确保浅水湖泊生态系统健康至关重要。我们提出了一个新的趋势-模式-服务（TPS）概念框架，用于综合研究时空景观变化过程及其生态效应。它由趋势变异分析、模式动态分析和服务功能分析三个部分组成。以1991年至2015年中国北方典型浅水湖泊白洋淀为研究案例，利用所提出的TPS框架来分析不同水位下由于失水和恢复而导致的景观变化的时空动态。结果如下。 (1)研究期间各景观类型存在不同程度的变化。当水深恢复到正常水平（7.86 m）时，浅水区比高水位年增加了136.63%，深水区减少了67.12%。 （2）景观格局向高度异质化、碎片化状态转变，景观类别逐渐均等化。 (3)生境质量评价显示适宜景观面积减少。因此，即使水位恢复，生境质量也没有改善，适宜生境景观逐渐被中等适宜生境景观所取代。考虑到不同水位的生境质量和景观变化之间的关系，在浅水湖泊的修复和管理中，必须综合考虑景观格局和生态系统服务。
Accurately grasping the dynamic change information of the landscape is essential for promoting sustainable land management aiming at ensuring the ecosystem health of shallow lakes. We proposed a new Tendency-Pattern-Service (TPS) conceptual framework for an integrated investigation of spatio-temporal landscape variations process and their ecological effects. It consisted of three components, namely, tendency variation analysis, pattern dynamics analysis, and service function analysis. Taking Baiyangdian Lake, a typical shallow lake in north China, between 1991 and 2015 as a study case, we used the proposed TPS framework to analyze spatio-temporal dynamics in landscape variations under different water levels due to water loss and recovery. The results were as follows. (1) Each landscape type varied in different degrees in the study period. When the water depth recovered to a normal level (7.86 m), the shallow water zone increased by 136.63%, while the deep water zone declined by 67.12% compared with that in a high water level year. (2) The landscape pattern changed toward a highly heterogeneous and fragmented state, and landscape categories gradually became equally. (3) Habitat quality evaluation showed the area of the suitable landscape was reduced. Thus, even when the water level recovered, the habitat quality was not improved and suitable habitat landscapes were gradually replaced by moderately suitable habitat landscapes. Considering the relationship between habitat quality and landscape changes in response to different water levels, it is important to take landscape patterns and ecosystem services into account comprehensively in lake restoration and management of shallow lakes.
