【摘要】 农牧交错区是我国传统农区与牧区相接壤和过渡的地带,在这个过渡带内种植业和草地畜牧业在空间上交错分布,时间上相互重叠。甘肃省农牧交错区包括15个县区,大多处于黄土高原干旱、半干旱区,这里生态环境脆弱,面临着一系列的生态问题,如水土流失;草地退化、沙化、盐渍化严重,草场承载力下降;土壤沙化,自然灾害频繁,沙尘暴时有发生等。如何既要保护和建设好脆弱的生态环境,又要促进该地区的经济社会发展是摆在我们面前的课题,解决好该地区可持续发展问题是一项复杂而艰巨的长期的工作。 本文选题于区域经济学、农业经济学和生态经济学等学科相互交叉、综合研究的前沿领域,以甘肃省农牧交错区为研究对象,运用定性分析和定量分析相结合的方法,以提高该地区可持续发展水平为目的,系统地对该地区可持续发展水平进行了调查、评价和分析,提出了该地区可持续发展的模式。具体内容如下: 首先介绍了甘肃省农牧交错区的地域概况,明晰了农牧交错区可持续发展内涵,从定性和定量两方面对本区可持续发展水平进行了评价。其中,在定量评价中,构建了评价本地区可持续发展水平的指标体系,该指标体系包括发展和可持续性两个子目标,发展子目标在于评价本地区的发展能力;可持续性子目标在于评价本地区资源和生命支撑系统的可持续性。运用该评价指标体系,算出了本区的各个县区的发展指数和可持续性指数,通过该指数可以评价本区的可持续发展水平:即本区的可持续发展水平处于基本可持续发展状态。 然后分析了造成甘肃农牧交错区发展现状的原因,这些原因主要是社会经济发展滞后;生态环境脆弱,生态承载力有限;生态立法不健全与保护意识淡薄等。针对这些原因,本文提出了促进本地区可持续发展的模式——生态经济。生态经济是可持续发展的内在要求,它注重资源的环境价值,是一种成本内化的经济;生态经济的建立同时需要必要的制度支持。生态经济要与本区的现状特点相结合,因此,进一步提出了使用于该区的具体的生态经济应用构想:农业产业化模式;节水经济模式;庭院经济模式:退耕还林还草、种草养畜模式。更多还原

【Abstract】 The transitional region between cropland and grassland is a particular zone, in which planting and animal husbandry are interlaced with each other. Agriculture and pasture interlaced region of Gansu province includes 15 counties that mostly lie on Plateau. It is a region with severe environmental problems such as soil erosion; vegetation degradation, desertification and soil salinization, the decline of carrying capacity of pasture; high frequency of natural calamity, the occurrence of sandstorm sometimes due to natural fragility enhanced by human activities. It is a difficult and important subject how to protect and built the fragile eco-environment, as well as brings about an advance in economy in this area.In the paper, the selected question is in the front field of the cross subjects such as regional economics; agriculture economics and ecological economics etc. The paper regards this area as the research object, uses the quantitative analysis method combined with qualitative analysis, and regards improving the sustainable development level in this area as object. It surveys sustainable development level in this area, appraises and analyses systematically. Make a concrete analysis as follows:Firstly, the paper introduces the natural overview of agriculture and pasture interlaced region of Gansu, ascertains the intension of sustainable development in this area, and appraises the sustainable development level according to qualitative analysis and quantitative angles. As regards quantitative analysis, the paper designs the evaluation index system of sustainable development in this region that includes two sub-goals that are the sustainability and development. Using the evaluation index system, we can calculate the development index and sustainability index of the counties in this region. From the indexes, we can appraise the level of sustainable development, that is to say, the level is in the basically sustainable state.Then, it analyses the reasons that lead the status of development and eco-environment. The reasons include that social and economic development is laggard; the ecological environment is fragile and the ecological carrying capacity is limited; the ecological legislation is imperfect and the consciousness of protecting is lack. Bases on the assessmentand analysis it puts forward the sustainable development mode--eco-economy. The modeembodies the internal signification of sustainable development, and attaches importance to the value of environment, as well as, the mode needs certain system. Finally, it puts forward the using model of eco-economics: agricultural industrialization mode; water-saving economy mode; courtyard economy; mode of grain for green, growing grass and raising domestic animal.更多还原
