Landscape is a heterogeneous area composed of different land units, which makes important contributions to improving human well-being by providing functions such as food security, species maintenance, livelihood opportunities, cultural and recreational activities. Landscape function assessment, as a pivotal tool facilitating sustainable development, aims to assess the potential for sustainable development in a given region and provide guidance for related decision-making. In order to elucidate the connotation of landscape function assessment and establish a clear research framework for comprehensive landscape function assessment, this paper categorizes the assessment into four dimensions: perception, ecology, characteristics, and performance based on the research focus. Furthermore, it provides a comprehensive review of each dimension's connotation, assessment methods, while also presenting future prospects. The findings suggest that: ①The preliminary implementation of perceptual dimensions has successfully shifted from subjective judgment to data-driven approaches. However, due to constraints such as limited availability of devices and lack of professional expertise, data acquisition remains relatively challenging. As a result, there hasn't been significant progress in quality assessment, performance evaluation or preference research when compared to traditional studies; ②In terms of ecological dimensions, the respective research frameworks and methods have been established to a certain extent. However, it is still necessary to establish a more precise evaluation framework in order to provide technical support for exploring the spatiotemporal dynamic characteristics and key driving factors of ecosystem evolution; ③The core issue of the feature dimension focuses on is "achieving landscape classification based on considering humanistic, historical, aesthetic, and ecological values", which presents a problem of diverse theoretical systems. The widely accepted and commonly used theoretical systems have not yet formed standards or regulations; ④The performance dimension emphasizes the sustainable development of landscapes, and is currently in the early stages of research with a lack of exploration on the correlation between landscape planning management strategies and their resulting benefits.In general, the assessment of landscape functionality demonstrates a trend towards multidimensional intersections and the integration of various theories and methods. However, there remains a relative neglect of the social, historical, and cultural aspects of landscapes, as well as a dearth of research frameworks for comprehensive landscape functional assessment. In the future, efforts should be made to strengthen landscape feature exploration, landscape functional map creation, landscape functional assessment, and landscape performance evaluation,to establish a comprehensive landscape functional assessment methodology that is multi-scale and multi-objective. This will help address the shortcomings in developing comprehensive landscape functional assessment plans.
