摘要
依据耦合协调度判定标准,结合相关理论研究,分析了安塞县商品型生态农业3个阶段与农业生态—经济系统和产业—资源子系统耦合协调度值的对应关系。结果表明,随着退耕还林工程的实施,安塞县商品型生态农业建设成效显著,系统综合发展指数由1999年的0.275 2增长到2010年的0.719 5;农业生态—经济和产业—资源系统的耦合协调度经历了先下降(1999—2001年)后增长(2002—2010年)的发展过程,但是,农业产业—资源子系统的耦合协调关系明显滞后于农业生态—经济系统;相应地,安塞县商品型生态农业建设先后经历了第Ⅰ阶段的生态系统结构建造时期和农业产业结构调整时期,并于2010年开始向第Ⅱ阶段(完善农业系统循环阶段)过渡。生态系统的改善和农业产业结构的调整促进了农业经济的快速增长,但是,相关产业的发展并未合理有效地利用农业生态资源。因此,应合理调整农业产业结构,完善系统链网结构,改变农业产业与资源的局部相悖态势,促进商品型生态农业系统的快速发展。
According to the measurement standard of coupling coordination degree and related research, it is clear that there were three phases in constructing the commodity-oriented eco-agriculture in Ansai County of North Shaanxi Province, which had the corresponding relation with coupling coordination degree of agricultural eco-economic system and industry-resource system. Since the implementation of grain for green project, great progress had been made in the construction of commodity-oriented eco-agriculture in Ansai County. The comprehensive development index of agriculture system rose from 0. 275 2 in 1999 to 0. 719 5 in 2010 with coupling coordination degree of agricultural eco-economic system and industry-resources system de- creased first（1999--2001）and then increased later（2002--2010）. However, the development of coupling co- ordination relationship within the industry-resources system lagged far behind that within the agricultural eco-economic system. Correspondingly, the commodity oriented eco-agriculture in Ansai County had gone through two phases as well. The first phase included the ecosystem construction period and agro-industrial structure adjustment period, and the second phase was the agriculture system improvement period started in 2010. The improvement of eco-system and adjustment of agro-industrial structure advanced the growth of agricultural economy, however, the agro-ecological resources had not been reasonably and effectively utilized. Therefore, it is important to adjust agro-industrial structure and improve the chain network in order to change the contradictory situation between agro-industries ment of the commodity oriented eco-agriculture. and resources utilization and promote the develop
