The impact of viaduct construction on the vegetation of a river valley was studied in Central Poland (Natura 2000 site PLH100006). The research aimed at assessing the suitability of ALS (airborne laser scanning), soil, and botanical data for monitoring the environmental effects of right-of-way reclamation 1 year after the road construction. Based on the data mentioned above, the following probl...
land-use spatial allocation is a multi-objective collaborative spatial optimization methodfor rational use of the land use. based on global search capabilities and the information feedbackmechanism of ant colony optimization (aco), a land-use spatial allocation model (aco-la) isproposed. firstlyfirst, a construction graph is built for modeling the land-use spatial allocationproblem. secondlysec...
abstract:â green spaces, especially urban gardens have been a subject of study in many countries for a long time, but the subject has been mostly overlooked in iran. therefore, this study tries to analyze the changes in land use and how we can protect green spaces (gardens) in jahrom in line with sustainable development in 1996-2006. the data in this study were collected through local investiga...
nowadays in trade and economic issues, prediction is proposed as the most important branch of science. existence of effective variables, caused various sectors of the economic and business executives to prefer having mechanisms which can be used in their decisions. in recent years, several advances have led to various challenges in the science of forecasting. economical managers in various fi...
This research aims to make a historical mapping of the development road infrastructure and impact on land use changes. A analysis was conducted based documents reports transportation development, construction, urban planning in Semarang City, capital city Central Java, Indonesia. From perspective, change City were determined by economic activities from early period colonialism, especially when ...
in recent years, changes in catchments water balance due to land use management have become the main concern of water resources authorities in iran. due to rapid population growth and land use changes, especially construction of taleghan dam, taleghan catchment has undergone rapid changes such as urban development, declining of rangelands, and deterioration of environment and erosion of soil re...
in the recent years, human activities have led to changes in land use and land cover, consequently, these changes lead to the structure and function of ecosystems. spatial-temporal change detection of land use is important to understand the relationships and interactions between human and natural resources and to make appropriate decisions due to changes in land use and land cover occurs in bro...
Slope instability and mass movement of soil are the most important concerns of road construction scientists and experts as well as environmentalists. Soil is the main material of forest road construction and forms the road bed. In this research in order to avoid time and cost waste in mechanic soil laboratory, the region was divided into same units based on landform in GIS software. 10 soil sam...
land use optimization using linear programing is a method in watershed management for access to production sustainability and decreasing of soil erosion. the sensitivity analysis of the model can with investigation of results influence form changes in input parameters, lead to decrease the uncertainty in decision-making of management programs. so in this research, linear programming model using...
Intraurban land-use change and factors affecting it are critical subjects in land-use planning. If unplanned, such changes can reduce the quality of life and spatial justice and ultimately lead to urban unsustainability. This paper aims to identify factors influencing unsustainable land-use change and analyze the intensity of such changes based on those factors. The artificial neural network an...
