Influence Of Upland Rice Improved Technology On The Agriculture Sustainable Development Of Mountainous Area

Yunnan province is located in the frontier of southwest China, which border on Vietnam, Myanmar and Laos as a minority mountainous area. The local food security problem not only concern livelihood, but also relate to the national unity and frontier stabilization. In the mountainous area of southwest Yunnan, Upland Rice (UR) is not only the important component of agriculture production, but also the main food source of local farmers. However, the local UR is almost distributed in the cold drought indigent mountainous area, which have complicated terrain, diversified climate and different economy development and cultivation patterns. In recent years, the agro-tech departments of Yunnan explored some innovative and progressed techniques to improve the agricultural productivity with protecting the environment. So, it has practical meanings and valuable reference to provide information and evidence for the development of mountainous economy and food security, by the research on sustainable development of mountainous area in southwest Yunnan in the context.With the mountainous agriculture development in Yunnan, This paper chose 7 sample villages from Lancang County, Menglian County and Jinghong City of southwest Yunnan, and adopted questionnaire and interview to survey the peasant households. Although the sample villages have different development stages, they are all depending on the UR development, so its representative to explore the influence process of UR technology. So, first, combined with related theories of sustainable agriculture development, this paper analyzed the influence of UR improved technology on the mountainous development of ecology, economy and society by qualitative analysis; then, demonstrate it by quantitative analysis with concrete index of each aspect, which is given by AHP method; finally, on the basis of theoretical and empirical analysis, this paper gave a comprehensive description and evaluation to the sustainable development of mountainous area in southwestern Yunnan.This paper concluded that the driven force of UR improved technology is obvious and active to the sustainable development of ecology, economy and society of mountainous area in southwest Yunnan. But the development difference existed in the sustainable development system, as the driven force extent is different in each aspect. In conclusion, this paper promoted pertinent suggestions included: Improve multi-cropping density, Extend high quality variety and Apply fertilizers rationally in ecology; Develop UR poverty alleviation, Broaden income sources and Explore UR industry in economy; Exert government function, Support minorities and Train technology ability in society.
