【摘要】 西藏自治区作为我国西部民族地区,经济发展一直滞后于东中部其他各省。加之其独特的生态地位,不能大力发展高污染、高能耗、高排放的第二产业。西藏地区具备典型的沟域经济特点,因此基于西藏经济的特殊性,综合考虑生态、经济社会的综合效益,构建适合西藏经济可持续发展的耦合模式不仅具有重要的理论意义,同时对藏民的增收具有较大的现实意义。本文的研究主要包括：(1)描述了西藏沟域经济体系的特点,即①沟中土地类型多样,垂直分异明显；②顺沟而走的纵向经济,沟口成为各沟的交汇点；③沟域内原有传统耦合模式正在打破,新的均衡却尚未建立；(2)在实地调研的基础上,以西藏“一江两河”地区为例,利用ArcGIS和SPSS软件构建了研究生态、经济和社会三系统的耦合效益分析。得出西藏的可持续发展与其自然地理系统有着的较强的相关性,但社会系统的发展却影响整个系统的主要因素。因此以生态保护为出发点,大力促进社会发展水平,将实现西藏经济的新的跨越；(3)以构建农牧业的有效耦合为突破点,即“沟顶繁育,沟谷育肥；支沟繁育,干沟育肥”耦合模式,提出了其他产业之间的有效耦合模式,实现西藏内部持续有效的循环经济；(4)在耦合模式和耦合效益模拟计算的基础上,本文提出了大力发展西藏“一江两河”地区经济的政策与措施,其中以农业和旅游业耦合为主导产业,大力发展基础设施,优化区域产业规划布局,促进特色产业化经营。更多还原

【Abstract】 The province of Tibet is a ethnic areas of China, which the economic development has lagged behind other provinces in the East Midlands. With its unique ecological status, Tibet is not suitable to choose the Second Industry as pillar industry, which brings the high pollution, high energy consumption, high emission. According to the special characteristics of the closed economic system of Tibetan areas, Tibet is a ditch economy. So considering the ecological, economic and social system, it has important theory significance to propose a sustainable coupling mode which also has realistic significance to increase the Tibet’s farmers income.This study mainly includes:(1) describe the ditch economic features of Tibet, such as①the various types of land in the ditch;②the conomic activity was happened along the ditch, and they get together in the intersections of ditches③the traditional coupling patterns are broken, but the new balance has not yet been established.(2) In based on the practical research in the "YLN" region of Tibet, using ArcGIS and SPSS software to build the coupled-benefit model to analysis the ecological, economic and social system. Analysis of the results turn out that the sustainable development of Tibet and its natural geographical system has a strong correlation, the most important is that the social system development are the main factor affect the whole system. Therefore to protect ecological as a start work, and promote the social development level vigorously, Tibet’s economy will achieve a new leap forward.(3) Building the agriculture mode which means "animals born on the top of the ditch and grown in the bottom; born in the tributary ditch and grown in the main ditch",and proposing the other effective coupling mode are proved that it could greatly improve the production level and sustainable development of ditch economy.(4) In base of building the coupling mode and simulate the benefit of the coupling mode, the paper proposed the policies and measures of developing the Tibet’s "YNL" region, in which to make the agriculture and tourism coupling as the leading industries,develop the infrastructure vigorously and optimize the regional industry planning and layout, the last one is to promote the characteristic industrialization.更多还原
