【摘要】：針對黃土丘陵區(qū)農(nóng)業(yè)產(chǎn)業(yè)—資源系統(tǒng)演變軌跡發(fā)生變化的現(xiàn)實(shí),參照農(nóng)業(yè)生態(tài)經(jīng)濟(jì)系統(tǒng)耦合過程模型,建立農(nóng)業(yè)產(chǎn)業(yè)—資源系統(tǒng)耦合過程模型。并對模型參數(shù)(k1,k2,k3,k4)的變化過程及其代表的生態(tài)經(jīng)濟(jì)意義進(jìn)行重點(diǎn)討論,在此基礎(chǔ)上對縣南溝流域進(jìn)行了實(shí)證。結(jié)果表明:不同參數(shù)k值組合,形成了不同的農(nóng)業(yè)產(chǎn)業(yè)—資源系統(tǒng)互動關(guān)系。退耕后,縣南溝流域資源所依賴的環(huán)境系統(tǒng)的提升空間現(xiàn)已達(dá)到極限,產(chǎn)業(yè)發(fā)展未建立在對資源的合理、有效利用上�，F(xiàn)階段資源系統(tǒng)發(fā)展態(tài)勢與資源系統(tǒng)演化速度和產(chǎn)業(yè)系統(tǒng)演化速度都成負(fù)相關(guān),產(chǎn)業(yè)系統(tǒng)發(fā)展態(tài)勢與資源系統(tǒng)演化速度和產(chǎn)業(yè)系統(tǒng)演化速度都成正相關(guān)。將碳匯產(chǎn)業(yè)融入系統(tǒng)后,可使資源系統(tǒng)演化速度提升2.56倍,若通過"輪牧+舍飼"養(yǎng)殖模式進(jìn)一步改良,可使資源系統(tǒng)演化速度提升4.66倍,使得資源得到合理、高效利用,加速產(chǎn)業(yè)結(jié)構(gòu)優(yōu)化升級。
[Abstract]:In view of the fact that the evolution path of agricultural industry-resource system has changed in the loess hilly region, the coupling process model of agricultural eco-economic system is referred to. The coupling process model of agricultural industry-resource system is established, and the change process of the model parameter (k1k2k2k3k4) and its ecological and economic significance are discussed emphatically. The results show that different parameter k values combine to form different interaction between agricultural industry and resource system. The improvement space of the environmental system on which the resources of the county Nangou watershed depends has reached the limit, and the industrial development has not been established in a reasonable way to the resources. At present, the development trend of resource system is negatively correlated with the speed of evolution of resource system and the speed of evolution of industrial system. The development trend of industrial system is positively related to the speed of evolution of resource system and industrial system. After the carbon sink industry is integrated into the system, the speed of evolution of resource system can be increased by 2.56 times. If the breeding model is further improved, the evolution speed of the resource system can be increased by 4.66 times, the resources can be used reasonably and efficiently, and the industrial structure will be optimized and upgraded.
