Landscape functional assessment research progress and insights
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;② In 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.
