Study on the Pattern of Rural Distinctive Eco-economy Based on Land Resources: A Case Study of Suide County in Loess Hilly Areas
黄土丘陵沟壑区农村特色生态经济模式探讨——以陕西绥德县为例

Based on the theory of regional human-land system in hilly & gully areas of the Loess Plateau,this paper analyzed the characteristic of agricultural resources and current status of social and economic development of Suide county in northern Shaanxi province,a typical case in Loess Plateau,and elucidated the interactive nature between explorations in ecological resources to aim at eco-environmental construction and the rural economic development.Results indicated that the factors restricting agricultural sustainable development in this study area are as follows:vulnerable ecological environment,serious soil and water erosion,shortage of water resources,poor economic condition,etc.Then based on the analysis of realistic social and environmental conditions,this paper discussed the effective ways to utilize ecological resources and develop eco-economy of Suide county in hilly & gully areas of the Loess Plateau.Driven by the western great development strategies during 2000-2004,the forest and orchard land in the study area increased by 7 178.5ha and 7 097.7ha,respectively.Furthermore,according to the characteristics of topography and rules of water and soil erosion,the typical optimal utilization technologies of land resources such as dry farming and saving irrigation technology,demonstration and popularization of tree planting practical technology,ecoagriculture for water protection technology,had been put forward.Finally,in order to guide the development of rural economy for building socialist new countryside in new stages,this paper also put forward three typical rural ecological economic patterns including Caragana korshinskii(Ningtiao) shelter industrialization model,three-dimensional soil and water protection agricultural model,and ecological resources development model in small watershed scale.
