I review here the spatially-resolved spectroscopic properties of low-redshift star-forming galaxies (and their retired counter-parts), using results from the most recent Integral Field Spectroscopy galaxy surveys. First, I briefly summarise the global spectroscopic properties of these galaxies, discussing the main ionization processes, and the global relations described between the star-formation rates, oxygen abundances, and average properties of their stellar populations (age and metallicity) with the stellar mass. Second, I present the local distribution of the ionizing processes, down to kiloparsec scales, and I show how the global scaling relations found between integrated parameters (like the star-formation main sequence, mass-metallicity relation and Schmidt-Kennicutt law) present local/resolved counter-parts, with the global ones being just integrated/average versions of the local ones. I discuss the local/resolved star-formation and chemical enrichment histories and their implication on the inside-out growth of galaxies. Third, I present the radial distributions of the surface densities of the properties explored globally, and how they depend on the integrated galaxy properties. Finally, I summarise all these results and discuss what we have learned from them regarding the evolution of galaxies.

低红移恒星形成星系的空间分辨光谱特性

我在这里回顾了低红移恒星形成星系（及其退休的对应部分）的空间分辨光谱特性，使用了最近的积分场光谱星系调查的结果。首先，我简要总结了这些星系的全球光谱特性，讨论了主要的电离过程，以及恒星形成率、氧丰度和它们的恒星种群（年龄和金属丰度）的平均特性与恒星质量之间描述的全球关系. 其次，我展示了电离过程的局部分布，低至千秒差距，并展示了在积分参数（如恒星形成主序、质量金属度关系和施密特-肯尼库特定律）之间发现的全局标度关系如何呈现局部/已解决的对应部分，全球版本只是本地版本的集成/平均版本。我讨论了局部/已解析的恒星形成和化学富集历史及其对星系由内而外生长的影响。第三，我展示了全球探索的特性的表面密度的径向分布，以及它们如何依赖于整合的星系特性。最后，我总结了所有这些结果，并讨论了我们从它们中学到的关于星系演化的知识。
