In landscape architecture, the concept of landscape has always been linked to two facets namely objectivity and subjectivity, and it has shown an inseparable bond between human and the environment. The tightknit and intertwined relationship of the qualitative and quantitative issues makes it difficult to understand and, consequently, to evaluate the landscape conceptt. During the history of landscape, and especially in recent years, many efforts have been made to assess the landscape and its various aspects. Most research has attempted to separate objective aspects from the subjective ones and numerically evaluate each one separately in a landscape assessment. Previous studies have evaluated the physique of environment, and human perceptions of the environment, some strands of studies have assessed the landscape assessed from the environmental aspect and investigated it ecologically, Some researchers have considered it objectively regardless of humans and their minds while, some have s viewed it as merely subjective issue. ITo assess the concept of landscape, it is necessary to simultaneously evaluate the objective and subjective process and discover the relations between them. Therefore, this research is an attempt to collect and organize library documents, including different methods of landscape evaluation in various objective and subjective fields, and to analyze them deductively and, and to study the existing methods, and suggest a model for landscape assessment.
