“…Forest litters are key cyclic materials in forest ecosystems, and play an important role in maintaining soil fertility, and promoting material and biological cycles, and nutrient balance [16]. Under the same climatic conditions, the main factor influencing the litter productivity is the forest type, and it varies with the tree species and spatial density of forest stands [17]. The paper studies the annual litter amounts of three forest stands in the Golden Mountain, i.e., Chinese fir plantation (1971.26 kg•hm −2 ), Cryptomeria fortunei plantation (2070.69 kg•hm −2 ), and evergreen and deciduous broad-leaved mixed forest (4742.93 kg•hm −2 ).…”

“…Litters of branches are greatly influenced by climatic conditions, especially wind, which blows down dead branches from previous months, causing changes in the litter productivity of branches in different months [23]. Affected by the combined influence of local climatic conditions and the ecological characteristics of tree species [17], the monthly dynamic changes in litter productivity of leaves are unimodal. For the evergreen and deciduous broad-leaved mixed forest, the litter productivity of leaves peaks in October due to the clear seasonal pattern of litter, with autumn having significantly higher litter productivity than other seasons.…”

“…Important functions have irreplaceable ecological roles, and a large amount of organic matter and mineral elements are transported from the canopy of plants to the soil surface through the litter. Therefore, the collection and measurement of forest litter are important means of studying the structure and function of forest ecosystems [5][6][7][8]. To a certain extent, litter yield and nutrient return are suitable indicators of the overall function of forest ecosystems and play a key role in forest ecosystem dynamics, nutrient cycling, and forest productivity [9][10][11][12].…”

“…Although in the past few decades, litter yield, structure and composition, decomposition rate, and its influencing factors have been extensively studied around the world, the existing dynamic changes of litter are mostly related to litter yield, nutrient The results of a single study on the return of elements or nutrients for one year are mostly planted forests, and there are relatively few studies on primitive natural forests [29][30][31]. In addition, the research on the evergreen broad-leaved forest in this region mainly includes the vegetation type and diversity research, and the multi-year comparative comprehensive research combining the dynamic law of litter yield and nutrient return is rarely reported [7,10,[32][33][34][35][36].…”

By studying the dynamic change characteristics of litter production, composition, nutrient content, and return amount of different components in different extreme weather interference years of Ailao Mountain evergreen broad-leaved forest, the paper provides theoretical support for the post-disaster nutrient cycle, ecological recovery, and sustainable development of the subtropical mid-mountain humid evergreen broad-leaved forest. Square litter collectors were randomly set up to collect litter. After drying to a constant mass, we calculated the seasonal and annual litter volume and the contents of organic carbon (C), total nitrogen (N), total phosphorus (P), total potassium (k), total sulfur (S), total calcium (Ca), and total magnesium (Mg). Finally, the nutrient return amount is comprehensively calculated according to the litter amount and element content. We tracked dynamic changes in litter quantity, nutrient composition, and nutrient components across different years. The results showed that the amount of litter from 2005 to 2015 was 7704–8818 kg·hm−2, and the order of magnitude was: 2005 (normal year) > 2015 (extreme snow and ice weather interference) > 2010 (extreme drought weather interference); the composition mainly included branches, leaves, fruit (flowers), and other components (bark, moss, lichen, etc.), of which the proportion of leaves was the largest, accounting for 41.70%–61.52%; The monthly changes and total amounts in different years exhibited single or double peak changes, and the monthly litter components in different years showed significant seasonality. In this study, the nutrient content of litter was higher than that of litter branches each year. The total amount of litter and the nutrient concentration of each component are C, Ca, N, K, Mg, S, and P, from large to small. The order of nutrient return in different years was the same as that of litter, and the returns of nutrients in litter leaves were greater than that of litter branches. The ratio of nutrient returns of litter and litter branches from 2005 to 2010 was 2.03, 1.23, and 3.69, respectively. The research shows that the litter decreased correspondingly under the extreme weather disturbance, and the impact of the extreme dry weather disturbance was greater than that of the extreme ice and snow weather disturbance. However, the evergreen broad-leaved forest in the study area recovers well after being disturbed. The annual litter amount and nutrient return amount is similar to that of evergreen broad-leaved forests in the same latitude and normal years in other subtropical regions. The decomposition rate and seasonal dynamics of litter nutrients are not greatly affected by extreme weather.

The seven typical plots were sampled and the contents of As, Cd, Cr, Cu, Ni, Pb and Zn were analyzed in order to investigate the heavy metal pollution of farmland soils surrounding scale pig farms in Nanchang. The heavy metal pollution was evaluated by using single pollution index and comprehensive index methods. The results were addressed that Cd and Pb were the major two pollutants in the farmland soils. The sequence of single pollution index was Cd, Pb, Ni, Cu, Zn, As and Cr. The competitive pollution index was 1.55, and the farmland soils were a slightly polluted grade. The correlation among heavy metals As, Cd, Pb, Cu and Zn were highly significant or significant, but the correlation among Cr, Ni and other heavy metals were not relevant.
