【摘要】 经济的飞速发展所带来的资源环境问题越来越被政府和公众关注。论文以地处青藏高原的甘南藏族自治州、青藏高原-黄土高原交汇区的临夏回族自治州和地处黄土高原的定西市为样本,通过主成分分析法建立定西、临夏、甘南人地系统的人类活动指数、生态环境指数、政策干预指数,阐明各要素相互作用的矢量过程；在此基础上,构建文化影响和政策干扰下的非参数回归模型,实现对1980年以来定西(汉)、甘南(藏)、临夏(回)三个子区域的人地耦合关系的演进分析,揭示人地关系的空间分异规律。结果表明：(1)人类活动指数、生态环境指数、政策干预指数具有地域一致性,1980-2010年31年间,定西、临夏、甘南三地区人类经济社会活动、生态环境、国家宏观政策具有相同或近似的演变轨迹,但其成因却各不相同。(2)人类活动、生态环境、政府干扰的三者耦合关系在研究期是不稳定起伏变化的,并具有显著区域差异性。定西生态环境在人类活动和政策干扰下呈倒U型曲面；甘南生态环境指数和人类活动指数及政策干预指数关系呈正U型曲面；临夏生态环境指数和人类活动指数及政策干预指数关系呈N型曲面。(3)三地生态环境指数波动都与政策变化有关,生态环境越脆弱地区,对政策干扰敏感性越高,制定环境相关政策需谨慎。未来应该加强政策引导,调动公民参与的积极性；在相关政策制定的过程中,增加政策的论证期以及公示期的必要环节,使各项政策的制定更加民主化。更多还原

【Abstract】 At present, environmental issues associated with rapid economic development were incorporated into government’s and people’s particular attention. This paper takes Gannan Tibetan Autonomous Prefecture, Linxia Hui Autonomous Prefecture and Dingxi City as samples, using principal component analysis to establish the coupling evolution indices of Human Land System, including human activity index, ecological environment index and policy interference index three hierarchies. On this basis, build non-parameter regression model under cultural impact and policy interference condition, to study the coupling evolution of Hum an-land system of Sino-Tibetan-Hui (STH) Ethnic Areas, revealing the space of man-land relationship differentiation law. The results indicate:(1) From1980to2008, human economic and social activities, ecological environment and policy interference of Dingxi, Linxia and Ganan have the same or similar evolutionary trajectory.(2) The coupling relationships among human activities, ecological environment and policy interference have significant regional differences, the relationship of ecological environment and human activities and policy interfere of Dingxi, Gannan and Linxia is inverted U-shaped curved surface, positive U-shaped surface and N-type surface respectively.(3) The ecological environment index fluctuated by the policy changing, the more fragile the ecological areas were, the higher the sensitivity of policy interference on its environment, so government develop environmental policies should be more cautious. In future, the government should strengthen policy guidance, mobilize the enthusiasm of citizen participation, and increase policy argumentation and publicity period, and make policy more democratization.更多还原
