摘  要：
通过野外定位小区试验,在生产能力、改土能力、能量流、价值流等方面对红壤侵蚀区常见的柑橘果园间作生态系统的生态经济效益进行了比较分析,并采用层次分析法对各系统的综合效益进行评价.结果表明:不管是果农间作、果肥间作还是果草间作均能很好利用自然资源,并能取得较好的生态、经济和社会效益;其中柑橘与花生和西瓜、柑橘与花生、柑橘与甘薯这几种间作系统能量和价值的输出高,但输入也高,在资金充足、劳力和肥料充裕时,选择其能获得很高的综合效益;柑橘与大叶猪屎豆、柑橘与百喜草、柑橘与印度豇豆这几种间作系统的能量和价值的输入较低,在资金紧张、劳力和肥料不足时,选择其也能获得较高的综合效益.

摘  要：
Through outdoor location plot experiment, the paper conducts analysis on ecological and economic benefit of orange orchard intercropping ecological systems which are common in red soil erosion area from aspects of producing ability, soil-improving ability, energy flow, value flow and so on; and also evaluates the comprehensive benefit of each system through stratification analysis method. The result indicates that orange orchard intercropping system, whether between fruit tree and crop, fruit tree and green manure or fruit tree and grass, all can make full use of natural resources, and gain better ecological, economic and social benefit. Intercropping systems including orange tree and peanut and watermelon, orange tree and peanut, orange tree and sweet potato can gain high output of energy and value, but the relevant input is high too, when the fund, labor and fertilizer are sufficient, the forenamed intercropping system can gain very high comprehensive benefit; intercropping systems including orange tree and big-leaf crotalaria, orange tree and paspalum notatum, orange tree and Indian cowpea need lower input of energy and value, but the output is lower too, when the fund, labor, and fertilizer are insufficient, these intercropping system also can get high comprehensive benefit.
