在广大山区,生态系统空间结构单一,基础结构脆弱,输出功能差,加之人口膨胀与系统输出能力不协调,制约着农村经济的发展。以小流域为单元,进行水土保持综合治理,建设高产、优质、高效生态经济系统,是解决这些地区贫困落后及生态失调的根本途径,甘肃临洮县沿沟流域正是为此进行的小流域试点。几年来,经过水土保持措施配置,土地利用结构调整,生物增产技术应用,农产品转化加工增值,促进了整个系统向有序结构演进,从而获取较好的经济、生态、社会综合效益。
In the vast mountainous areas, the single spatial structure of ecosystem, fragile infrastructures, poor output function, and the uncoordinated population expansion and system output constraints restrict the development of rural economy. Small watershed as a unit for comprehensive management of soil and water conservation, construction of high yield, high quality and efficient eco-economic system is to solve these areas the basic way of poverty and backwardness and ecological imbalances, Gansu Lintao County is the valley for this small watershed pilot . In recent years, through the allocation of soil and water conservation measures, the adjustment of land use structure, the application of bio-stimulation technology and the conversion of agricultural products, the entire system has been promoted to an orderly structure, thereby obtaining better economic, ecological and social benefits.
