Exploring relation between Environmental Indexes and Soil erotion for sustainable development

چکیده مقاله:
Today, with increasing human population and more usage of natural resources is cause of needing to environmental management more than before. Global experiments show that appearance of unsustainability environmental Indexes is the cause of undesirable natural resources management and harmful effects on environmental. Thus attention to sustainable development principle that is based on advantage use of natural and environmental resources is an emergency factor so that no harm to resources. Soil erosion is most important factor of degradation in watersheds. Also protection management for sustainable operation from natural resources need to diagnose and studding about environmental indexes and their relationship beside the human factor effects. Studding of relationship between environmental indexes on soil erosion with MPSIAK model is the purpose of this study on Ravang watershed (Minab: Hormozgan). We use MPSIAK model because of more analysis of environmental indexes than other models and for estimate erosion rate and correlation between factors. Using of base map and statistical data shows that 6/88 M.tons of sediment extract per year from Ravang watershed and level of sedimentation and erosion grading is in 3 classes III, IV, V and 74/57 % of its area 7980/38 h is in III level sedimentation. Amounts of relation between environmental indexes with using of Pierson correlation coefficient has done in SPSS and results show that significance between all indexes with emphasis of land cover and land use.
