Evaluating the Effect of Land Use Changes On Some Soil Chemical Properties (Case Study: Central Ramshir, Khouzestan, Iran)

The progressive growth of population and improvement of living standards lead the world to the increased demand for food and water. The past management of agriculture and terrestrial ecosystems has imposed so much pressure on the soil capacity and the environment performance in order to meet the needs of the growing human population to maintain the global balance of matter and energy. Thus, land use change could show a profound impact on the soil and land environment. Given the importance of the subject, the study was conducted on the land use changes and the impact of these changes on some chemical properties of soil in some part of central Ramshir of Khouzestan Province with an area of 500 acres. With land use changes from grassland to irrigated cultivation, electrical conductivity has increasedby17.1% and acidity, organic matters and calcium carbonate have been reduced by 1.6, 5.71 and 0.22%, respectively. This study showed that dealing with the environment components should be consistent with their long-term career potential. It means that the use of these resources should be consistent with all phenomena and natural rules of their survival. If such rules are not considered, the soil quality will be reduced gradually and this critical context of the environment will face a serious crisis. Finally, land use change can reduce the quality and increase the soil degradation and can be followed by Undesirable consequences in the long run.
