Abstract: What kind of landscape space is good or better? For a long time it cann't be answered by landscape architecture, the reason is not only the lacking of general evaluation system , but also the lacking of stable value orientation and specification of landscape space performance. The question which puzzled landscape space performance has been a key point in landscape architecture. Landscape architecture is an evidence-based discipline and the systematic and quantifiable landscape performance can provide a quantitative method and instrument for evidence-based research of landscape planning and design. However the relative assessing system now we using cann't satisfy the performance evaluation of landscape space which with multi-scales and multi-functions. This research thinks that a stable reference system is necessary for the performance evaluation of landscape space which ecological system service is very important character to operate. Based on the theory of ecological system service and bridging it to landscape scape with the characteristics of multi-scales, multi-functions and measurability, this paper build a framework composing of ecological, economic and cultural performances, which includes 12 evaluation criteria and 33 evaluation indicators.
