Taking typical western ethnic pastoral area- Evenki Autonomous Banner in Inner Mongolia Autonomous Region as an example, this article analyses the factors restricting income increase of herdsman penetratingly as follows: the growth in revenue of animal husbandry in pastoral area is limited by ecology; the infrastructure construction in pastoral area lags behind, and the development of animal husbandry is still sluggish; the overall level of industrialization operation of agriculture and animal husbandry is not high; the employment structure of herdsman is simple, and the channel of income increase is narrow; the transfer of labor forces in pastoral area shows "pumping-like transfer"; herdsmen enjoy few national policies of supporting agriculture and benefiting farmers, and the policy support is short. On the basis of the actual situation in western ethnic minority areas, following countermeasures and proposals are put forward for increasing herdsman's income: transform the mode of production and operation, enhance the organization degree of the majority of herdsmen; improve infrastructure conditions, and promote comprehensive production capacity of agriculture and animal husbandry; quicken pace of industrialization, strengthen the construction of technology support and service system; speed up human capital accumulation rate of herdsman, improve self-development ability of herdsman; propel transformation of production pattern of animal husbandry, innovate ecological protection construction mechanism; increase subsidies for animal husbandry, pastoral area and herdsman in western ethnic minority areas, strengthen policy implementation.
