The importance of incorporating landscape dynamics into population viability analysis (PVA) has previously been acknowledged, but the need to repeat the landscape generation process to encapsulate landscape stochasticity in model outputs has largely been overlooked. Reasons for this are that (1) there is presently no means for quantifying the relative effects of landscape stochasticity and popu...
This paper will concentrate on the result of a research based on comparative study between two Persian gardens in different micro climates in arid regions. Sustainability could be observed in many aspects and elements of traditional Iranian architecture and landscape architecture, and this method of design has used to solve many problems for many centuries. Gardens of Iran have had special role...
Dynamic spatial analysis addresses computational aspects of space-time processing. This paper describes the development of a spatial analysis tool and modelling framework that together offer a solution for simulating landscape processes. A better approach to integrating landscape spatial analysis with Geographical Information Systems (GIS) is advocated in this paper. Enhancements include specia...
The sensitivity of landscape metrics to the scale effect is one of the most challenging issues in landscape ecology and quantification of land use spatial patterns. In this study, fractal dimension was employed to assess the effect of scale on the sensitivity of landscape metric in the north of Iran (around Sari) as the case study. Land use/ cover maps were derived from Landsat-8 (OLI sensor) i...
In this paper, we propose a quantitative indicator for measuring and ranking real estate from the perspective of the surrounding landscape by integrating the building information model (BIM) and the three-dimensional geospatial information system (3DGIS) based on the AHP method. The landscape is one of the qualitative variables which it's measuring and quantifying is a complex task. In previous...
Implementing watershed management without considering all aspects may lead to instability, exacerbating unfavorable conditions. Adopting an integrated management approach is necessary for any watershed system. An important consideration in decision making and planning process is to quantify ecological impacts of management using landscape ecology framework. In this regard, uncertainty quantific...
We develop a landscape stewardship classification which distinguishes between farmers' understanding of landscape stewardship, their landscape values, and land management actions. Forty semi-structured interviews were conducted with small-holder (<5 acres), medium-holders (5-100 acres), and large-holders (>100 acres) in South-West Devon, UK. Thematic analysis revealed four types of stewardship ...
Many studies indicated that industrialization and urbanization caused serious soil heavy metal pollution from industrialized age. However, fewer previous studies have conducted a combined analysis of the landscape pattern, urbanization, industrialization, and heavy metal pollution. This paper was aimed at exploring the relationships of heavy metals in the soil (Pb, Cu, Ni, As, Cd, Cr, Hg, and Z...
Shape-from-shading and shape-from-texture methods have the serious drawback that they are applicable only to smooth surfaces, while real surfaces are often rough and crumpled. TO extend such methods to real surfaces we must have a model that also applies to rough surfaces. The fractal surface model [Pentland 831 provides a formalism that is competent to describe such natural 3-D surfaces and, i...
