Bottom Line: The results suggested that the texture of soil sample was sandy.It can be included that afforestation can improve the soil quality to some extent, which can be partly reflected from the indexes like TOC, TN, TP, K(+), MBC, and DOC.And the characterization of DOM implied that UV humic-like substances were the major fluorophores components in the DOM of the soil samples, which consisted of aliphatic chains and aromatic components with carbonyl, carboxyl, and hydroxyl groups.

ABSTRACT
In this study, soil samples collected from different plain afforestation time (1 year, 4 years, 10 years, 15 years, and 20 years) in Miyun were characterized, including total organic carbon (TOC), total nitrogen (TN), total phosphorus (TP), available K (K(+)), microbial biomass carbon (MBC), and dissolved organic carbon (DOC). The DOM in the soil samples with different afforestation time was further characterized via DOC, UV-Visible spectroscopy, excitation-emission matrix (EEM) fluorescence spectroscopy, and (1)H NMR spectroscopy. The results suggested that the texture of soil sample was sandy. The extracted DOM from soil consisted mainly of aliphatic chains and only a minor aromatic component. It can be included that afforestation can improve the soil quality to some extent, which can be partly reflected from the indexes like TOC, TN, TP, K(+), MBC, and DOC. And the characterization of DOM implied that UV humic-like substances were the major fluorophores components in the DOM of the soil samples, which consisted of aliphatic chains and aromatic components with carbonyl, carboxyl, and hydroxyl groups.

Mentions: As a typical afforestation area, Xi Tian Ge Zhuang town of Miyun District was selected as sampling region, as illustrated in Figure 1. The mean annual rainfall and average temperature of this area is 661.3 mm and 10.8°C, respectively. Five sampling regions with different plain afforestation time (1 year, 4 years, 10 years, 15 years, and 20 years) were selected in this study, and the samples were collected on June 27th, 2015 (Table 1). At each sampling area, 5 samples were collected with columns of 20 × 5 cm (long × diameter) via Soil Core Samplers (AMS samplers, American Falls, Idaho) [9, 13].
