摘要: 江西适合油茶生长,但开发利用程度不高,分析评估其生产潜力与资源利用效率,可为进一步优化油茶种植分区、提高产量、合理利用国土资源等提供依据。以江西省油茶综合生产潜力为研究对象,基于潜力衰减法逐级修订得到自然生产潜力,结合社会有效系数得到综合生产潜力,并进行资源利用效率评估。结果表明: 1)江西省油茶各级生产潜力平均值在10229~17724 kg·km-2,从赣南向赣西北递减,平均综合生产潜力为12550 kg·km-2,分级后具有较高潜力和高潜力类可利用土地面积达51656 km2,占全省面积的31.1%;市级生产潜力中,赣州最高。2)江西省油茶生产潜力变幅为2223~3857 kg·km-2,各级潜力变化量的区域差异较小;油茶资源满足率为69.3%~122.7%,各级资源满足率区域差异较小;油茶资源组合利用效率为49.1%~85%,各级生产潜力利用率的区域差异较大。3)综合生产潜力评估结果与江西油茶实际产量较符合,资源利用效率评估结果与江西自然和社会条件相符,可以作为相关研究与政策制定的参考。

Abstract: As an area suitable for the plantation of Camellia oleifera, Jiangxi had a low degree of development and utilization. Evaluating its potential productivity and resource utilization efficiency could provide reference for optimizing C. oleifera planting division, increasing yield and rationally utilizing land resources. Natural production potential of C. oleifera in Jiangxi was estimated by stepwise revised potential attenuation method. The comprehensive potential productivity was estimated by combined with social efficiency coefficient, with the resource utilization efficiency being evaluated. There were three main results. 1) Potential productivity of C. oleifera in Jiangxi varied from 10229 to 17724 kg·km-2, which decreased from the south to the northwest, with an average potential of 12550 kg·km-2. After classification, the area with higher and highest potential productivity reached 51656 km2, accounting for 31.1% of the total area. Among the cities, Ganzhou had the highest potential productivity. 2) The changes of potential productivity of C. oleifera ranged from 2223 to 3857 kg·km-2, with small regional difference for various levels. The resource satisfaction rate ranged from 69.3% to 122.7%, with small regional difference. The resource utilization efficiency varied from 49.1% to 85%. Regional utilization rate at all levels differed obviously. 3) The estimated comprehensive potential productivity was in line with the real production of C. oleifera in Jiangxi, and the assessed resource utilization efficiency was consistent with natural and social conditions. These results could be used as a reference for related research and policy making.
