        Background and Objective: Despite the increasingly trend of developmental activities that are likely to change the structure and change or eliminate landscape functions and processes in Iran ultimately, it seems necessary to consider the visual effect in EIA studies especially in northern ecosystem of the country. Methods: This study aimed to quantify the visual criteria of naturalness and complexity using SHDI, SHEI, PLAND, LPI, PR, PD, and NP measurements in the area of Tonekabon's Dohezar-Sehezar watershed from two viewpoints. The visible range, after land use mapping and production of DSM and transmitting of visibility points to GIS, was obtained using the Visibility instruction in GIS, which analyzed the visible range at two points. Findings: According to the PLAND index, the highest amount pertained to forest land use, and their amounts for forest, agriculture, and rangeland land uses found 0.1499, 0.0001, and 0.0021 respectively that detected the naturalness in the first- viewpoint was more than the second viewpoint, and this area has been less affected by human interferences. At the second point, except for the SHEI value which was less than the first point ( 0.0927), the amount of SHDI (0.0927), PR(7000), PD (2.507), and NP(2058000) indices grater than second point obtained. Discussion and Conclusion: The use of landscape metrics with regard to their capabilities can be a useful step to early identification of the impacts of development on the structure of landscape. The proposed approach can be the basis for developing a new method to understanding the effects of landscape changing in planning and management fields. Manuscript profile

        Environmental Impact Assessment (EIA) is a process of identifying, predicting and mitigating the negative impacts of development projects on physico-Chemical, biological, socio-economic and cultural environments. The main purpose of EIA process is to inform decision makers of the likely impacts of a proposal before a decision is made. EIA provides an opportunity to identify key issues and stakeholders early in the life of a proposal so that potentially adverse impacts can be addressed before final approval decisions are made. There are different methods for implementing an EIA project. The best method is one, which can quantify the impacts and assess the impacts rapidly. This paper attempts to investigate and compare capabilities of the EIA prevalent methods including questionnaire, matrix, system analysis, maps overlay, networks and ELECTRE-TRI multi-criteria decision method. This paper indicates that ELECTRE_TRI is an appropriate method for EIA projects. However, the final judgment of the selection of EIA method depends on the EIA experts opinions. Manuscript profile
