abstract soil invertebrate and their spatial pattern are affected strongly by environmental factors. spatial variability of soil properties is one of the most important reasons of the macrofauna variability. this study was conducted to investigate the spatial variability of soil properties and soil macrofauna biomass in the riparian forest landscape of karkhe river. soil macro fauna were sample...

Spatial patterns are suitable tools for optimal management in many forested areas. In this research, the effect of conservation on spatial pattern of dominant trees has been studied. To achieving this purpose, protected and non- protected forests were selected in Masal region of Guilan province as the study area. Sampling methods including fixed- area plots and distance methods, such as T- squa...

Migration and quality of redistribution of population across country is one of the main factors that planners take into account to control population and guide its movements to economic poles. Scientific recognition of migration phenomenon is important for managing and policy making in the country. These movements change migration pattern, in a way that along with increase in population and the...

poverty can have spatial dimensions. while general figures might show the spatial pattern of poverty, there is a need for more detailed examination of this pattern. relying on simple figures of spatial patterns and ranking regions based on them might be misleading. this paper tries to apply spatial analysis methodsm, namely spatial autoregressive models to find out the impacts of space on the h...

Spatial pattern of trees can possibly indicate stand history, population dynamics, and species competition. This research was investigated in the Chahartagh forest reserve, Ardal region, chaharmehal and Bakhtiari Province, Central Zagros forest, and southwest Iranian state. In this study 53 hectare of the study area was selected and perfect inventory.  Information includes the position and kind...

One of the important features of plant communities is the spatial pattern of trees. The spatial pattern of the stands determined by measuring and positioning of trees in the stands and inserting them in analytical frameworks. This is because spatial information allows natural resource managers to make and perform better-informed decisions, -. The aim of this study was to assess the spatial patt...
