Paradigm of integrated soil and water conservation in rolling hill regions with black soil in Northeast China
摘要
Abstract
Rolling hill regions are main grain producing areas in Northeast China, where are characterized by seriously soil and water loss on slope farmland. Based on the characteristics of black soil erosion and the experience on soil erosion control in rolling hill regions of Northeast China, the mechanism of integrated soil erosion control is summarized. Moreover, the paradigm of integrated soil and water conservation on farmlands with long and gentle slope target to food security is presented. Structures of the paradigm system are analyzed, and also the benefits from the applications of the paradigm system are analyzed. Thus the study could supply the integrated soil erosion control theory in rolling hill regions with black soil in Northeast China. The results show that integrated control on soil and water loss in rolling hill regions with black soil should be dominated by the erosion control on slope farmland, and mainly regulated by the surface runoff control, channel erosion control and land productivity control. The paradigm system is supported by two sub-systems, and they are ecological security sub-system and food security sub-system. The structures of the paradigm system are consist of the structure of soil erosion protection system, structure of ecological agriculture technique system and their coupling. And the results suggest that this kind of paradigm system could provide scientific and practical references for the coordinated development of socio-economic-environmental systems in rolling hill regions with black soil of Northeast China.关键词
