Sustainable development theory, combined with the theory of sociology, economics and other disciplines, to Minqin County social - economic - environmental system as the research object, using a combination of theoretical analysis and comparative analysis method of Minqin County economy bearing capacity, calculation and analysis of the relative carrying capacity of resources, Minqin County social - economic - environmental systems balance between comprehensive and detailed evaluation, the following conclusions: 1. Minqin County is still grim ecological and environmental problems of water resources due to The contradictions will continue to exist for a long time, simultaneously irrational industrial structure, development, lack of motivation, coordination of resources and environment and socio-economic development caused by the dual pressures. 2. Economic capacity analysis results showed that the prominent structural contradictions, with the total GDP, the secondary industry, tertiary industry growth, labor resources, performance, low efficiency of human resources for the extensive use of the characteristics Minqin County industrial base is weak, compatible; economic growth, further widening the income gap between urban and rural areas. Water resources, arable land, grassland outside the load range with sustainability. Raw coal, diesel, electricity, resource utilization is not high, tap potentials. The number of motor-pumped wells belonging absolute carrying, to some extent reflects the serious situation of groundwater overexploitation. The amount of fertilizer practical are relatively intensive bearer, and that the high efficiency of farming fertilizer applications in the process of economic growth, consistent with the recent years Minqin County specialty farming trends. Industrial wastewater emissions to meet environmental requirements, while governance investment lagged behind economic growth. Minqin County relative capacity analysis results showed that the 2002-2005 and 2008 of Minqin County relative economic resources carrying capacity generally upward trend, but still the state of overloading; relative carrying capacity of land resources remain flat, slightly rich, relative water The carrying capacity of resources was a clear downward trend. Economic growth in the cost of the investment and consumption of large amounts of water, the high proportion of resource consuming industries, reflecting the extensive growth characteristics. The overall carrying capacity of resources in the overloaded state, can carry the population is still in decline. The results show that the comparative analysis with the relative carrying capacity of the two counties and one district within the region due to the different natural resource endowments, different development model, Liangzhou as the socio-economic and cultural center of the Wuwei region, economic carrying capacity is much higher than other counties economic development is relatively intensive, and the relative lack of natural resources; Minqin, Gulang, the Tianzhu economic development is lagging behind, in Minqin and the Gulang farmland resources are relatively abundant the Tianzhu County hosts the main advantage water resources. Can optimize the industrial structure within the region as a whole, to effectively avoid resource constraints the status quo, is conducive to the complementary advantages to achieve the coordinated development of the region as a whole. The analysis results show that compared with similar Hexi Corridor region, the degree of resource abundance have some impact on the socio-economic development mode. Jinta County, Guazhou County not only outstanding carrying capacity of water resources, the relative economic carrying capacity is also higher than in Minqin County. For the Minqin County resources bearer status quo, to reduce dependence on natural resources, and to ease the pressure on ecological environment, the need to improve economic carrying capacity to proceed, and vigorously promote the development of secondary and tertiary industries efforts to change the socio-economic development model, in order to effectively improve the socio-economic ecological environment and harmonious relations.
