摘　　要：通过对江西省鹰潭市纯林(南酸枣)、农林复合(南酸枣间作花生)、纯农(花生单作)3种农业模式的土壤质量及其生态生理效应的研究,初步发现该区典型复合农林系统的净光合速率等生理生态功能最高,可达到单作的2倍以上,并且具有维持和提高土壤肥力的功能,是该地区值得进一步研究和推广的模式。The soil quality and ecophysiology effect of three agricultural patterns in low hilly land of red soil region were studied , and the result showed that the agroforestry system had the highest ecophysiological function. Its net photosynthesis rate was two times higher than that of the monoculture, and it could maintain or improve soil fertility. So it were worth for studying and popularizing in the region.
