高寒农牧交错区生态重建与经济发展互动模型及应用研究

An Analysis on Interactive Relationship between Ecology Reconstruction and Economic Development in the Alpine Farming-pastoral Ecotone

以高寒农牧交错区为研究对象,运用灰色关联法,建立了高寒农牧交错区生态重建与经济发展的互动模型。模型结果表明:(1)生态重建与地区经济发展之间存在极强的关联性,二者互为驱动,相互促进,交互耦合构成生态经济系统;(2)在生态与经济互动中,经济系统的影响占优,表明经济贫困是生态重建的最大限制因素;(3)农户作为生态重建和经济发展的行为决策者是生态经济互动链的节点。在此基础上,结合样点村实际,选择林药结合的退耕模式、移民搬迁、建设小城镇和发展反季节蔬菜基地等作为实现研究区经济与生态协调发展的具体模式与有效途径。

The Alpine Farming-pastoral Ecotone is one of eco-fragile region. With Grey Related Analysis as the main method,a model concerning the interaction between ecology reconstruction and economic development in the Alpine Farming-pastoral Ecotone had been developed. The results were as follows：① There was a strong correlation between the Project of Cropland Conversion into Forest or Grass Land and local economic development. These two work together to build a harmonious ecological economic system. ②In the Interactive relationship,the influence of economic system was predominant. This indicated that poverty was the key factor limiting the improvement of ecological environment. ③As the actor of the ecological reconstruction and economic development,farmer was playing a key role between these two. Then,the Interactive Model had been modified according to the realities of the sampled village,Xinping Village. Based on the results of the concrete model,some recommendations were put forward,such as fitted patterns of returning cropland to forest,relocation,and the construction of small rural towns. They are possible to better the ecological environment and improve the economic for setting a sound foundation for future development.
