Soil and water resources are important elements of the environment that is managed to reduce the erosion rate and the destructive effects of torrential *** of the measures to reach this goal requires the ranking of sub-watersheds and areas within the sub-watersheds,from most to least vulnerable,which can be achieved using Multi-criteria decision analysis *** this paper,using the Preference Ranking Organization Method for Enrichment Evaluations(PROMETHEE)Ⅱ method ranking of nine sub-watersheds delineated in the Topciderska river watershed,Serbia,was performed by using ArcGIS *** criteria used for determining the order of the most vulnerable sub-watersheds are land cover,rainfall,soil erodibility as well as *** importance of criteria was determined by using the Analytic Hierarchy Process(AHP)method,and the influence of the criteria weights on ranking results was *** research identified that the most vulnerable sub-watershed is located in the upper part of the study area,where 15% of the territory is at high risk of ***,this sub-watershed should have priority for protection through the implementation of appropriate measures and *** results of the PROMETHEE Ⅱ method and the ArcGIS application represent the valuable information for watershed management planning and implementation of soil erosion and torrent control measures.

Land use optimization for sustainable development of mountain regions of western Serbia

引用

Journal of Mountain Science 2018年第7期15卷 1471-1480页

This study analyses the possibilities for optimal land use structure in mountainous areas of rural Serbia, which is faced with problems such as unfavorable terrain characteristics and inadequate land use patterns causing economic underdevelopment and increasing population migration. In the case of a small privately owned farm in Western Serbia, optimal land use pattern is determined using the linear programming model. The objective function-cost-effectiveness or soil erosion reduction, as well as constraints, are formulated using the benefit-cost ratio(BCR) for a 15-year production period and soil losses data calculated using the Universal Soil Loss Equation(USLE). The best results are achieved using the scenario with the aim to minimize soil erosion, considering the BCR in the constraints. This scenario is proposed since it was registered that the benefit for landowners would increase by five times, while the losses of land would decline about 80%. The sensitivity analysis of investments is performed to check whether the price variation affects the cost-effectiveness of proposed land use. Results show that market changes(nine cases are considered) do not lead to significant changes in land use allocation. Proposed land use pattern improves the environmental condition, strengthens the rural economy and thus offers the greatest potential for sustainable development of mountainous rural areas.
