Abstract

针对黄土丘陵区农业产业—资源系统演变轨迹发生变化的现实,参照农业生态经济系统耦合过程模型,建立
农业产业—资源系统耦合过程模型。并对模型参数(k1,k2,k3,k4)的变化过程及其代表的生态经济意义进行重点讨
论,在此基础上对县南沟流域进行了实证。结果表明:不同参数k值组合,形成了不同的农业产业—资源系统互动关
系。退耕后,县南沟流域资源所依赖的环境系统的提升空间现已达到极限,产业发展未建立在对资源的合理、有效利
用上。现阶段资源系统发展态势与资源系统演化速度和产业系统演化速度都成负相关,产业系统发展态势与资源系
统演化速度和产业系统演化速度都成正相关。将碳汇产业融入系统后,可使资源系统演化速度提升2.56倍,若通过
“轮牧+舍饲”养殖模式进一步改良,可使资源系统演化速度提升4.66倍,使得资源得到合理、高效利用,加速产业结
构优化升级。

Other Abstract

In view of the development of agricultural industry-resource system in Loess Hilly region,we established
a coupling process model of agricultural industry-resource system following the agricultural ecologicaleconomic
coupling process model,and we analyzed the coupling situation of system.We focused on the
ecological and economic significance of model parameters(k1,k2,k3,k4)and conducted an empirical study
on the Xiannangou watershed.The results show that different parameter combination forms the different
agricultural industry-resource system interactive relationship.After returning farmlands to the natural lands,
the space of resources that relied on environmental systems has reached the limit now,and the development
of industry is not based on the rational and efficient use of resources in Xiannangou watershed.The development
trend of resource system is negatively related to the evolution speed of the resource system and the
industrial system.The development trend of industry system is positively related to the evolution speed of
the resource system and the industrial system.The account in of carbon sink can make the optimized system
evolution speed increase by 2.56times.On the basis of that,the agricultural system can be promoted by
4.66times through rotational grazing and house feeding mode,which makes the resources be rationally and
efficiently used and accelerates the optimization and upgrade of industrial structure.
