Phosphorus (P) is an important element in terrestrial ecosystems and plays a critical role in soil quality and ecosystem productivity. Soil total P distributions have undergone large spatial changes as a result of centuries of climate change. It is necessary to study the characteristics of the horizontal and vertical distributions of soil total P and its influencing factors. In particular, the influence of climatic factors on the spatial distribution of soil total P in China’s forest ecosystems remain relatively unknown. Here, we conducted an intensive field investigation in different forest ecosystems in China to assess the effect of climatic factors on soil total P concentration and distribution. The results showed that soil total P concentration significantly decreased with increasing soil depth. The spatial distribution of soil total P increased with increasing latitude and elevation gradient but decreased with increasing longitude gradient. Random forest models and linear regression analyses showed that the explanation rate of bioclimatic factors and their relationship with soil total P concentration gradually decreased with increasing soil depths. Variance partitioning analysis demonstrated that the most important factor affecting soil total P distribution was the combined effect of temperature and precipitation factor, and the single effect of temperature factors had a higher explanation rate compare with the single effect of precipitation factors. This work provides a new farmework for the geographic distribution pattern of soil total P and the impact of climate variability on P distribution in forest ecosystems.

“…As microplastic dynamics lead to a certain spatial distribution of microplastics in soil profiles and soilscapes, we can study this spatial distribution in the field and deduce on the processes that formed this distribution. This was proposed by Weihrauch (2019) to investigate soil phosphorus dynamics. In the present paper, we transfer this 'geospatial approach' to microplastic research.…”

“…Furthermore, it is evident from publications on microplastics in soils that often relatively small sample numbers are processed because the respective analyses are rather cumbersome (see following chapters). For instance, Scheurer and Bigalke (2018) (3) To develop a suitable sampling strategy, two dimensions of spatial resolution should be considered, the lateral (i.e., soilscape) and the vertical (i.e., soil profile; Weihrauch, 2019). Soils result from and are shaped by pedogenic and environmental processes, which do not just affect one location (i.e., one spot in coordinate space) but larger spatial areas (e.g., landscape sections).…”

“…Several soil profiles along the slope would be required that have a lateral context with each other. Weihrauch (2019) proposes three options for the lateral context of soil sampling sites: (a) no lateral context (i.e., samples are taken randomly and not interpreted in a genetic context with each other), (b) a linear context (e.g., in transects/catenae), and (c) a two-dimensional context (e.g., mapping of a surface area; Figure 3b). Of the seven published field studies on microplastics in soils, five are based on random sampling, one on transects, and one on area mapping (Table 3).…”

Studies on microplastics in soils is currently being established as a new research field.So far, mainly 'explorative studies' have been carried out to detect microplastics in different soil environments. To generate a deeper understanding of microplastics dynamics, 'systematic studies' are required. Such research must built on a targeted sampling strategy and considerate fieldwork and sample handling. From literature enquiry, a five-stage methodological workflow was deduced for studies on microplastics in soils.In the present review, the spatial representation of soils/soilscapes with microplastics in soils research is conceptually and practically assessed. We discuss judgmental, randomized, and metric soil sampling strategies. Then, we explain sample pre-processing and give a brief overview of methods for microplastics identification and quantification. We conclude that the establishment of the novel field of research 'microplastic dynamics in soils' requires more intensive consideration of soil sampling strategies. As soil is a complex medium and the soilscape is spatially heterogeneous, we highlight systematic sampling strategies as the best possible options for sophisticated research.However, no overall optimum methodology can be defined because the specific strategy must be in line with the particular research question. For all studies on microplastics in soils, practical improvement is needed to prevent contamination of soil samples with plastics during sampling and sample pre-processing.

Due to human activities, the overabundance of regional nitrogen/phosphorus (N/P) has a huge impact on ecological environment worldwide. It is necessary to comprehensively understand the human‐induced N/P input and spatiotemporal variations of nutrients in a river. As the adjustment to the spatial structure of Beijing, the Beijing's subcenter is an important strategic position in promoting the coordinated development of Beijing–Tianjin–Hebei. In this study, the dynamic changes of ammonia nitrogen (NH3‐N) and total phosphorus (TP) from 2012 to 2022 were analyzed, then the net anthropogenic N input (NANI) and net anthropogenic P input (NAPI) was estimated in the Beijing's subcenter. The results showed that both NH3‐N and TP had an overall downward trend with a three‐stage pattern. The NANI and NAPI declined from 5.68 × 104 and 0.95 × 104 to 0.78 × 104 and 0.15 × 104 kg km−2 per year, respectively. The chemical fertilizers input accounted for the largest part at 53–81% of NANI and 49–80% of NAPI. There were high values of N and P input in the southeast of Tongzhou, and the fluxes of N and P were positively correlated with the input of anthropogenic N and P in the Chaobai River Basin (Tongzhou District) and the Beiyun River Basin (Tongzhou District). This study would provide the foundation for setting priorities and enacting more targeted N/P management strategies in the Beijing's subcenter.
