摘  要:
为探讨退耕还林还草工程实施后商品型生态农业系统演变态势及其影响因素的变化情况,借鉴已有研究结果,建立商品型生态农业系统综合评价指标体系,运用生态位评价的多边形综合指标法和灰色关联分析法,对1998-2008年安塞县商品型生态农业系统演变过程进行了定量分析。结果表明:研究期内,安塞县商品型生态农业系统综合生态位显著提高,系统发展的主要影响因素也随之变化。依据系统综合生态位发展曲线,目前农业资源和经济效益是安塞县商品型生态农业系统发展的主要影响因素,通过提高资源有效利用率,协调产业与资源关系,有望进一步推动商品型生态农业系统的发展。

摘  要:
For probing into the evolution situation and influencing factors of commodity-oriented agro-ecosystem(CA) under the Grain for Green Project,the composite evaluation index of agricultural eco-economic system was built by referring to previous results.The evolution of CA in Ansai County from 1998 to 2008 was analyzed by utilizing the polygon synthesis indicator approach and the grey correlation analysis approach.Results showed that: complex ecological niche of CA advanced significantly.Meanwhile,influencing factors for system development varied.According to the complex ecological niche curves,currently,agro-resources and economic benefit were the main influencing factors for the development of CA.In the future,the ecological agro-system development would be promoted by improving the resource-utilization efficiency and optimizing the consistency between industry and resources.
