背景和目的在非林地上建立的人工林在增强陆地碳固存方面发挥着重要作用。了解人工林土壤C、养分和化学计量学的变化对森林管理具有重要意义。MethodsWe对139篇文献中的人工林矿质土壤C、N、P和S及其化学计量学的变化进行了全球荟萃分析。在农田造林后，土壤水分含量略有增加，在荒地造林后，土壤水分含量显著增加。造林对土壤全磷无明显影响，但草地和农田造林后土壤速效磷明显减少。土壤养分（N、P和S）的变化和化学计量比（C：N、C：P和N：P）的变化与土壤C动态显著相关（p< 0.05）。土壤固碳是最低的在寒带，更大的种植园下与N固定的物种比非固定species.ConclusionChanges在造林后的土壤C和养分主要是不同的前土地利用。与草地造林相比，荒地造林是一种更有效的固碳途径。
Background and aimsPlanted forests, established on non-forest lands, play an important role in enhancing terrestrial carbon (C) sequestration. Understanding the changes in soil C, nutrients and stoichiometry in planted forests is important for forest management.MethodsWe conducted a global meta-analysis of changes in C, nitrogen (N), phosphorus (P) and sulfur (S) and their stoichiometry in mineral soils of planted forest across broad climatic zones from 139 papers.ResultsSoil C and N are slightly decreased after forestation on grassland, moderately increased after forestation on cropland, and substantially increased after forestation on barren land. Forestation does not affect total soil P, but the available P is significantly depleted after the forestation of grassland and cropland with N-fixers. Changes in soil nutrients (N, P and S) and shifts in stoichiometry (ratios of C:N, C:P and N:P) are significantly related to soil C dynamics (p< 0.05). Soil C sequestration is the lowest in the boreal zone, and greater under plantation with N-fixing species than under non-fixing species.ConclusionChanges in soil C and nutrients after forestation mainly differ to prior land use. Compared with forestation of grassland, forestation of barren land is a more effective approach to enhancing C sequestration.
