This study tracked six years of dynamic change in agricultural structure, function, and diversity in Xiaodiantou Village, Gejiu City, Yunnan Province, China, as an example of suburban eco-agriculture. Results showed: (1) the structure shifted from a conventional, single food-production type to a commercial economic type combining hog raising, biogas, food crops, forestry, fruit, and vegetables; (2) economic benefit and the output-input value ratio increased gradually; (3) output of matter and energy increased with input, but the output-input ratio of energy and matter decreased when input became excessive; and (4) system diversity was closely related to structure and function, increasing as structure and function improved. Based on these findings, a measure for sustainable development was proposed.
