this research has been carried out with the aim of the determination of the land-use changes of the forests in the protected area of arasbaran. the determination of the changing points and the factors influencing these changes by the use of gis and remote sensing are the main aims of this research. accordingly, the satellite pictures pertaining to the years 1987 and 2005 along with other necess...

unprincipled changes in land use are major challenges for many countries and different regions of the world, which in turn have devastating effects on natural resources, Therefore, the study of land-use changes has a fundamental and important role for environmental studies. The purpose of this study is to detect and predicting of land use/ land cover (LULC) changes in Darab plain through the Ma...

gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...

Knowledge of rangeland vegetation characteristics as well as factors affecting it in environmental planning, land management and sustainable development is very important. However, regional and up-to-date maps of pasture vegetation cover are not always available. In this study, in order to plot the vegetation cover percentage of the rangelands and monitor its changes in drought and wet periods,...

Measures of forest structure provide an important indication of productivity, health and the growth stage of a forest. Using traditional field-based approaches, extraction of such structural parameters is often time consuming and labour intensive. Remote sensing is a cost effective technique for mapping and interpreting some features of vegetation; and LiDAR provides highly accurate measurement...

Leaf Optical Properties (LOPs) convey information relating to temporally dynamic photosynthetic activity and biochemistry. LOPs are also sensitive to variability in anatomically related traits such as Specific Leaf Area (SLA), via the interplay of intra-leaf light scattering and absorption processes. Therefore, variability in such traits, which may demonstrate little plasticity over time, poten...
