家庭菜园是印度尼西亚南苏拉威西省农村社区普遍采用的农林类型之一。这项研究的目的是确定构成家庭菜园的物种的多样性水平及其对农民收入的贡献。研究变项主要为家庭菜园地的宽度变化及社区的社会经济背景。研究结果表明，在小块土地上，群落以树木为边界，种植一年生作物，穿插农产品，在较宽的土地上，群落将各种植物整合在一起。家庭菜园的多样性指数为1.25 ~ 2.18，属中等水平;物种均匀度指数为0.49 ~ 0.77，属中等水平。家庭菜园的总收入在不同的群落之间差异很大，主要取决于组成物种的组成和密度。家庭菜园对农民收入的贡献率为43.27%~ 49.06%。家庭菜园农林业的可持续管理可以为农民的收入以及保护生物多样性和环境做出重大贡献。
Home-garden is one of the types of agroforestry which is commonly practiced by rural communities in South Sulawesi, Indonesia. The study aimed to determine the diversity levels of the species constituting the home-gardens and their contribution to the farmers’ incomes. The variables used in the study were the widths variation of the land owned as the home-gardens and the socioeconomic backgrounds of the community. The study results indicated that in small land, the community cultivated annual crop plants interspersed with agricultural commodities, and the trees as the boundary, while in the wider land they integrated various species plants within the area. The diversity index of the home-gardens was categorized as moderate with a value of 1.25 to 2.18, while species uniformity index was ranging from moderate to high with values of 0.49 to 0.77. The total incomes from home gardens varied greatly from one community to another, and it was largely determined by the composition and density of the constituent species. The contribution of the home-gardens to the income of the farmers amounted to 43.27%–49.06%. The sustainable management of the home-garden agroforestry can give a significant contribution to the farmers’ incomes and the preservation of biodiversity and environment.
